🔥 Advanced Terminal Tips & Tricks

#

🧠 1. Master Bash Shortcuts

#

🧾 2. Use Aliases to Save Time

#

Define shortcuts in ~/.bashrc or ~/.zshrc:

alias gs='git status'
alias ll='ls -lah --color=auto'
alias c='clear'
alias ..='cd ..'

Then reload with source ~/.bashrc.

🧰 3. Use Functions for Complex Tasks

#

Example: extract any archive format

extract() {
  if [ -f "$1" ]; then
    case "$1" in
      *.tar.bz2) tar xjf "$1" ;;
      *.tar.gz) tar xzf "$1" ;;
      *.zip) unzip "$1" ;;
      *.rar) unrar x "$1" ;;
      *) echo "Unknown format" ;;
    esac
  else
    echo "'$1' is not a valid file"
  fi
}

⌛ 4. Use tmux or screen for Terminal Sessions

#

• Run long processes without worrying about disconnection

• Split terminal windows

• Reattach sessions later:

  tmux
  tmux attach

🔍 5. Search & Reuse Commands

#

history | grep ssh

Or use reverse search with Ctrl + R, then type a keyword.

📁 6. Jump to Directories Quickly

#

Use autojump:

j projects

It learns your habits and allows you to jump to frequently visited folders.

🧪 7. Use Process Substitution

#

Compare output of two commands:

diff <(ls /etc) <(ls /usr/etc)

📋 8. Copy Output to Clipboard

#

Depends on system:

ls | xclip -selection clipboard       # Linux (X11)
ls | pbcopy                           # macOS

⚙️ 9. Use xargs Like a Pro

#

Example: delete all .bak files

find . -name "*.bak" | xargs rm

Or parallel execution:

cat urls.txt | xargs -n 1 -P 10 curl -O

🐚 10. Customize Your Prompt (PS1)

#

Example:

export PS1="\[\e[32m\]\u@\h:\w \$\[\e[0m\] "

Try Starship Prompt for a powerful, cross-shell prompt.

📡 11. Run Commands Over SSH Easily

#

ssh user@host 'df -h'

📜 12. Use tee to View and Save Output

#

ls -l | tee output.txt

🔄 13. Loop Through Commands

#

Example: batch rename

for f in *.JPG; do mv "$f" "${f%.JPG}.jpg"; done

🧮 14. Use Arithmetic

#

echo $(( 10 + 5 ))

⏱️ 15. Time Commands

#

time tar czf archive.tar.gz folder/
