Every seasoned developer knows the .bashrc file is where terminal magic happens. Customizing it properly can save hundreds of keystrokes per day. Here's my curated collection of time-saving configurations refined over a decade of development work.

# Enhanced ls commands
alias ll='ls -alhF --group-directories-first --color=auto'
alias la='ls -AF'
alias lt='ls -alhtF --time-style=long-iso'  # Sorted by modification time
alias lx='ls -lXB'  # Sort by extension
alias lr='ls -lR'   # Recursive ls

# Disk space analysis
alias diskspace="du -h --max-depth=1 | sort -hr | head -n20"
alias bigfiles="find . -type f -exec du -h {} + | sort -rh | head -n20"

# Process management
alias pstop="ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%cpu | head"

Remember to source your .bashrc after making changes: source ~/.bashrc or open a new terminal session. These aliases represent just the beginning - tailor them to your specific workflow for maximum efficiency.

The .bashrc file is your command-line Swiss Army knife. Every serious developer I know has spent hours fine-tuning theirs. Here are battle-tested configurations that have saved me countless hours over the years.

# Enhanced ls commands
alias ll='ls -alh --group-directories-first --color=auto'
alias la='ls -A --block-size="\'1"'
alias lt='ls -ltrh'  # sort by time
alias l.='ls -d .*'  # show hidden files

# Find large files quickly
alias findlarge="find . -type f -exec du -sh {} + | sort -rh | head -n 20"

# Disk space visualization
alias diskspace="du -h --max-depth=1 | sort -hr"
alias freespace="df -h | grep -v 'tmpfs'"

# Process management
alias pscpu="ps auxf | sort -nr -k 3 | head -10"
alias psmem="ps auxf | sort -nr -k 4 | head -10"

# One-line git status
alias gs='git status -sb'
alias gd='git diff --color-words'
alias gl="git log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset'"
alias gca='git commit --amend --no-edit'
alias gprune="git fetch --prune && git branch -vv | grep ': gone]' | awk '{print \$1}' | xargs git branch -D"

# Quick IP info
alias myip="curl ifconfig.me && echo"
alias ports="netstat -tulanp"

# Download utilities
alias wget='wget -c'  # resume by default
alias curljson='curl -s -H "Content-Type: application/json"'

# Python virtualenv
alias venv='source venv/bin/activate'
alias mkvenv='python3 -m venv venv && venv'

# Docker shortcuts
alias dps="docker ps --format \"table {{.ID}}\t{{.Names}}\t{{.Status}}\t{{.Ports}}\""
alias dcu="docker-compose up -d"
alias dcd="docker-compose down"

# Create directory and cd into it
mkcd() { mkdir -p "$1" && cd "$1"; }

    case $1 in
      *.tar.bz2) tar xvjf $1 ;;
