LFCS Part 51: Using Aliases and Keyboard Shortcuts

Introduction

You've learned about command history, Tab completion, pipes, and variables—all powerful tools for working efficiently in the terminal. But there's one more productivity feature that can save you countless keystrokes every day: aliases.

Aliases allow you to create custom shortcuts for commands you use frequently. Instead of typing git status dozens of times a day, you can create an alias gs that does the same thing. Combined with powerful keyboard shortcuts like Ctrl-A (jump to beginning of line) and Ctrl-E (jump to end), you'll be navigating the terminal faster than ever before.

In this comprehensive guide, you'll learn everything about bash aliases and essential keyboard shortcuts. By the end, you'll have a personalized set of aliases and master the keyboard shortcuts that experienced Linux users rely on every single day.

What Are Aliases?

An alias is a custom shortcut for a command or series of commands. Think of it as a nickname for a longer command.

Why use aliases?

• Save time: Type less, work faster
• Avoid typos: One-word shortcuts for complex commands
• Standardize: Create consistent commands across systems
• Safety: Add confirmation prompts to dangerous commands
• Productivity: Customize your shell to match your workflow

Simple example:

# Instead of typing this every time:
ls -lah --color=auto

# Create an alias:
alias ll='ls -lah --color=auto'

# Now just type:
ll

Creating Aliases

To create an alias, use the alias command with this syntax:

Syntax:

alias name='command'

Important rules:

1. No spaces around the = sign
2. Use quotes around the command
3. Single quotes preserve the literal command
4. Alias names can't contain spaces or special characters

Basic Alias Examples

# Clear screen shortcut
alias c='clear'

# List files in long format
alias ll='ls -la'

# Go to parent directory
alias ..='cd ..'

# Go up two directories
alias ...='cd ../..'

# Show disk usage in human-readable format
alias df='df -h'

# Show memory usage in human-readable format
alias free='free -h'

Now when you type c, it runs clear. When you type ll, it runs ls -la.

Aliases with Options

# Always show colors with grep
alias grep='grep --color=auto'

# Human-readable du with totals
alias du='du -h'

# mkdir with parent directories
alias mkdir='mkdir -p'

# Interactive copy (asks before overwriting)
alias cp='cp -i'

# Interactive move (asks before overwriting)
alias mv='mv -i'

# Interactive delete (asks for confirmation)
alias rm='rm -i'

Aliases for Navigation

# Quick directory navigation
alias home='cd ~'
alias docs='cd ~/Documents'
alias dl='cd ~/Downloads'
alias desk='cd ~/Desktop'

# Go to frequently used directories
alias proj='cd ~/projects'
alias logs='cd /var/log'
alias etc='cd /etc'

Aliases for Common Commands

# Show top 10 processes by CPU usage
alias topcpu='ps aux --sort=-%cpu | head -11'

# Show top 10 processes by memory usage
alias topmem='ps aux --sort=-%mem | head -11'

# Show open ports
alias ports='netstat -tuln'

# Check public IP
alias myip='curl -s ifconfig.me'

# Ping with 5 packets
alias ping='ping -c 5'

# Get weather (example)
alias weather='curl wttr.in'

Aliases with Multiple Commands

Use semicolons to run multiple commands:

# Update system (Debian/Ubuntu)
alias update='sudo apt update && sudo apt upgrade'

# Update system (RHEL/CentOS)
alias update='sudo dnf update'

# Clear screen and show directory
alias cls='clear && ls'

# Git add, commit, push
alias gacp='git add . && git commit -m "Update" && git push'

Viewing Aliases

View All Aliases

# Show all currently defined aliases
alias
alias ..='cd ..'
alias c='clear'
alias cp='cp -i'
alias df='df -h'
alias ll='ls -la'
alias mv='mv -i'
alias rm='rm -i'

View Specific Alias

# Check what a specific alias does
alias ll
alias ll='ls -la'

# Check if an alias exists
alias myalias 2>/dev/null || echo "Alias not found"

Check if Command is an Alias

Use type to see what a command is:

type ll
ll is aliased to `ls -la'

type ls
ls is /usr/bin/ls

type cd
cd is a shell builtin

Removing Aliases

Temporarily Remove an Alias

Use unalias to remove an alias from the current session:

# Create an alias
alias ll='ls -la'

# Remove it
unalias ll

# Now ll doesn't work:
ll
bash: ll: command not found

Remove All Aliases

# Remove all aliases (use with caution!)
unalias -a

Bypass an Alias Temporarily

If you have an alias but want to run the original command:

# You have: alias ls='ls --color=auto'
# Run original ls without color:
\ls

# Or use full path:
/bin/ls

# Or use command:
command ls

Making Aliases Permanent

Aliases created in the terminal only last for the current session. To make them permanent, add them to your ~/.bashrc file.

Add Aliases to ~/.bashrc

Method 1: Edit the file directly

# Open ~/.bashrc in your editor
nano ~/.bashrc

# Scroll to the end and add your aliases:
# My custom aliases
alias ll='ls -lah'
alias c='clear'
alias ..='cd ..'
alias update='sudo apt update && sudo apt upgrade'

# Save and exit (Ctrl-O, Enter, Ctrl-X in nano)

Method 2: Append from command line

# Add alias to ~/.bashrc
echo "alias ll='ls -lah'" >> ~/.bashrc
echo "alias c='clear'" >> ~/.bashrc

Apply Changes

After modifying ~/.bashrc, reload it:

# Method 1: Source the file
source ~/.bashrc

# Method 2: Use dot notation
. ~/.bashrc

# Method 3: Start a new bash session
bash

Organize Aliases in a Separate File

For better organization, create a dedicated file:

# Create an aliases file
nano ~/.bash_aliases

# Add your aliases there:
alias ll='ls -lah'
alias c='clear'
alias ..='cd ..'

Then source it from ~/.bashrc:

# Edit ~/.bashrc
nano ~/.bashrc

# Add this line:
if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

Now your aliases are in a separate, organized file.

Useful Alias Collections

Safety Aliases

Protect yourself from accidents:

# Confirm before overwriting
alias cp='cp -i'
alias mv='mv -i'
alias rm='rm -i'

# Make rm safer (verbose and interactive)
alias rm='rm -iv'

# Prevent accidentally removing root
alias rm='rm --preserve-root'

# Create trash function instead of rm
alias trash='mv -t ~/.trash'

Essential Keyboard Shortcuts

Keyboard shortcuts are just as important as aliases for productivity. Here are the essential ones every Linux user should know.

Navigation Shortcuts

Move the cursor:

| Shortcut | Action | Example Use | |----------|--------|-------------| | Ctrl-A | Jump to beginning of line | Fix command prefix | | Ctrl-E | Jump to end of line | Add argument at end | | Ctrl-B | Move backward one character | Same as ← arrow | | Ctrl-F | Move forward one character | Same as → arrow | | Alt-B | Move backward one word | Jump between words | | Alt-F | Move forward one word | Jump between words |

Examples:

# You typed: sudo apt install vim
# Cursor is at end, you want to add 'sudo' at the beginning:
# Press Ctrl-A to jump to start:
|sudo apt install vim
# Type 'sudo '

# You typed: ls /var/log/
# You want to add a filename at the end:
# Press Ctrl-E to jump to end (if cursor is elsewhere)
ls /var/log/|

Editing Shortcuts

Modify the command line:

| Shortcut | Action | Example Use | |----------|--------|-------------| | Ctrl-U | Delete from cursor to beginning of line | Clear command prefix | | Ctrl-K | Delete from cursor to end of line | Clear command suffix | | Ctrl-W | Delete word before cursor | Remove last argument | | Alt-D | Delete word after cursor | Remove next word | | Ctrl-D | Delete character under cursor | Remove single char | | Ctrl-H | Delete character before cursor | Same as Backspace | | Ctrl-Y | Paste (yank) previously deleted text | Restore deleted text |

Examples:

# You typed: sudo systemctl restart nginx
# You want to change 'restart' to 'stop':
# Position cursor on 'restart', press Alt-D to delete word:
sudo systemctl | nginx
# Type 'stop '

# You typed: sudo apt install package-name-wrong
# You want to clear everything after 'install':
# Position cursor after 'install', press Ctrl-K:
sudo apt install |
# Type correct package name

# You accidentally deleted something with Ctrl-U or Ctrl-K:
# Press Ctrl-Y to paste it back

Screen and Process Control

Control terminal behavior:

| Shortcut | Action | Example Use | |----------|--------|-------------| | Ctrl-L | Clear screen | Quick cleanup | | Ctrl-C | Interrupt (kill) current process | Stop running command | | Ctrl-Z | Suspend current process | Pause process | | Ctrl-D | EOF (End of File) or logout | Exit shell | | Ctrl-S | Freeze terminal output | Pause scrolling | | Ctrl-Q | Unfreeze terminal output | Resume scrolling |

Examples:

# Long output filling your screen:
# Press Ctrl-L to clear and start fresh

# Command running too long:
ping google.com
# Press Ctrl-C to stop it

# Want to pause a process and come back later:
vim largefile.txt
# Press Ctrl-Z to suspend
[1]+ Stopped     vim largefile.txt
# Do other work, then resume with: fg

# Exit the shell:
# Press Ctrl-D (same as typing 'exit')

History Shortcuts

Navigate command history (covered in detail in Post 48):

| Shortcut | Action | Example Use | |----------|--------|-------------| | Ctrl-R | Reverse search history | Find previous command | | Ctrl-G | Cancel reverse search | Exit search | | ↑ | Previous command | Navigate history | | ↓ | Next command | Navigate history | | Alt-. | Insert last argument of previous command | Reuse argument | | !! | Repeat last command | Rerun command |

Command Execution Shortcuts

| Shortcut | Action | Example Use | |----------|--------|-------------| | Ctrl-O | Execute command and keep it in prompt | Run and edit | | Alt-# | Comment out current line | Save for later | | !! | Execute last command | Quick rerun | | !$ | Last argument of previous command | Reuse argument |

Combining Aliases and Shortcuts

The real power comes from combining aliases with keyboard shortcuts.

Example workflow:

# Create useful aliases
alias ll='ls -lah'
alias ..='cd ..'
alias gs='git status'

# Navigate quickly
# Type 'll' to list files
# See a directory you want to enter
# Type 'cd dir' but realize you need 'sudo'
# Press Ctrl-A to jump to start
# Type 'sudo '
# Press Ctrl-E to jump back to end

# Edit a long command
# Type a long command with an error in the middle
# Press Ctrl-A to jump to start
# Press Alt-F to jump forward word by word to the error
# Fix it and press Enter

# Recall and modify
# Press Ctrl-R, type 'git', find 'git commit -m "message"'
# Press Ctrl-A, Ctrl-K to keep 'git commit -m "'
# Type new message

Advanced Alias Techniques

Aliases with Arguments

Aliases don't directly support arguments, but you can use functions:

# This doesn't work well:
alias greet='echo Hello'
greet John  # Output: Hello John (works by accident)

# For real argument handling, use functions:
mkcd() {
    mkdir -p "$1" && cd "$1"
}

# Use it:
mkcd projects/new-app
# Creates directory and changes into it

Conditional Aliases

Create aliases based on system type:

# In ~/.bashrc
if [ -f /etc/debian_version ]; then
    # Debian/Ubuntu
    alias update='sudo apt update && sudo apt upgrade'
elif [ -f /etc/redhat-release ]; then
    # RHEL/CentOS
    alias update='sudo dnf update'
fi

Aliases That Override Commands

# Make ls always use colors
alias ls='ls --color=auto'

# Make rm safer
alias rm='rm -i'

# Make mkdir create parent directories
alias mkdir='mkdir -p'

# To use original command, prefix with backslash:
\ls  # Runs original ls without alias

Temporary Aliases

Create an alias just for the current session:

# Create temporary alias
alias temp='echo This is temporary'

# Use it
temp
This is temporary

# After logout/login or closing terminal, it's gone

Practical Alias Examples for Different Roles

For Developers

# Development servers
alias serve='python3 -m http.server 8000'
alias phpserve='php -S localhost:8000'

# Node.js
alias ni='npm install'
alias ns='npm start'
alias nt='npm test'

# Code formatting
alias format='prettier --write .'

# Testing
alias test='npm test'

# Build
alias build='npm run build'

For System Administrators

# Monitor logs
alias tailf='tail -f'
alias syslog='sudo tail -f /var/log/syslog'
alias auth='sudo tail -f /var/log/auth.log'

# Service management
alias reload='sudo systemctl daemon-reload'
alias services='systemctl list-units --type=service'

# Resource monitoring
alias top='htop'
alias mem='free -h'
alias disk='df -h'

# Network
alias ports='netstat -tuln'
alias ips='ip addr show'

For Database Administrators

# PostgreSQL
alias psql='psql -U postgres'
alias pgstart='sudo systemctl start postgresql'
alias pgstop='sudo systemctl stop postgresql'
alias pgstatus='sudo systemctl status postgresql'

# MySQL
alias mysql='mysql -u root -p'
alias mystart='sudo systemctl start mysql'
alias mystop='sudo systemctl stop mysql'

# MongoDB
alias mongo='mongosh'

Best Practices for Aliases

1. Keep Aliases Short and Memorable

# Good: Short, intuitive
alias ll='ls -lah'
alias c='clear'
alias gs='git status'

# Bad: Too long, defeats the purpose
alias list-all-files-in-long-format='ls -lah'

2. Don't Override Important Commands

# Risky: Overriding ls completely might cause issues
alias ls='ls -lah'  # Now plain 'ls' always shows all files

# Better: Create a new alias
alias ll='ls -lah'  # Keep 'ls' as-is

3. Document Your Aliases

# In ~/.bashrc or ~/.bash_aliases
# === Navigation aliases ===
alias ..='cd ..'
alias ...='cd ../..'

# === Git aliases ===
alias gs='git status'
alias ga='git add'

# === System aliases ===
alias update='sudo apt update && sudo apt upgrade'

4. Test Before Making Permanent

# Test in current session first
alias ll='ls -lah'
ll  # Try it out

# If it works, add to ~/.bashrc
echo "alias ll='ls -lah'" >> ~/.bashrc

5. Use Functions for Complex Logic

# Alias (simple)
alias gs='git status'

# Function (complex - takes arguments)
gcom() {
    git add .
    git commit -m "$1"
    git push
}

# Use it:
gcom "Fixed bug in authentication"

6. Check for Name Conflicts

# Before creating an alias, check if it exists:
type ll
# If it returns "not found", you're safe

# If it shows a command or alias, choose a different name

Troubleshooting Aliases

Problem 1: Alias Not Working

Symptom: You created an alias but it doesn't work.

Solutions:

# 1. Check if alias exists:
alias myalias

# 2. Reload ~/.bashrc:
source ~/.bashrc

# 3. Check for typos:
alias ll='ls -lah'  # Correct
alias ll='ls -lah'  # Wrong (smart quotes)

# 4. Check syntax (no spaces around =):
alias ll='ls -lah'  # Correct
alias ll = 'ls -lah'  # Wrong

Problem 2: Alias Not Permanent

Symptom: Alias works now but disappears after logout.

Solution:

# Add to ~/.bashrc:
echo "alias myalias='command'" >> ~/.bashrc
source ~/.bashrc

Problem 3: Alias Not Working in Scripts

Symptom: Alias works in terminal but not in scripts.

Explanation: Aliases are not expanded in non-interactive shells (scripts).

Solution: Use functions instead or source ~/.bashrc in script.

Problem 4: Alias Conflicts

Symptom: Alias doesn't do what you expect.

Solution:

# Check what the name currently means:
type ls
ls is aliased to `ls --color=auto'

# Remove conflicting alias:
unalias ls

# Create new alias:
alias myls='ls --color=auto'
