What are your favorite bash aliases?

alias myips="ifconfig | sed -En 's/127.0.0.1//;s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p'" shows a listing of your IP addresses, works great if you have multiple /dev/eth* (OSX/nix)

My favorite

alias fuck='sudo !!'

Some functions inside my .zshrc

function clock() {
    watch -t -n1 "echo "" && date +""$'  '"%T""
}

function c() {
    clear; cd $1; l;
}

(for mac users)

# Change directory to the current Finder directory
function cdf() {
    target=`osascript -e 'tell application "Finder" to if (count of Finder windows) > 0 then get POSIX path of (target of front Finder window as text)'`
    if [ "$target" != "" ]; then
        cd "$target"; pwd
    else
        echo 'No Finder window found' >&2
    fi
}

One I must have when I use Sublime Text

alias slt='subl'

When I do presentations on my Mac I like to hide the mess on my desktop.

alias hideDesktop='defaults write com.apple.finder CreateDesktop -bool false; killall Finder;'
alias showDesktop='defaults write com.apple.finder CreateDesktop -bool true; killall Finder;'

Start my screensaver

alias afk="open /System/Library/Frameworks/ScreenSaver.framework/Versions/A/Resources/ScreenSaverEngine.app"

Send my Mac to sleep:

alias sleep="pmset sleep now"

List global installed packages and bottles.

alias npml='npm list -g --depth=0'
alias brewl='brew leaves'

Some of my favorites:

Merges current branch into master then git checkout back to develop

alias mergemaster='git checkout master; git pull; git merge develop; git push; git checkout develop'

Adds everything from current folder to git

alias add='git add .'

For Node developers:

alias s='npm start'

alias lint='npm run lint'

Docker:

alias dockerstop='docker-compose stop'
alias dockerup='docker-compose up -d'
alias dockerrm='docker-compose rm --all'

In last few months I started using ZSH + http://ohmyz.sh/ as my default shell and it’s AWESOME!

My favorite alias/function:

randompw()
{
    cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w ${1:-32} | head -n 1
}

Keep all your bash history:

export HISTTIMEFORMAT="%s "
PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND ; }"'echo $$ $USER \
               "$(history 1)" >> ~/.bash_eternal_history'

extract files:

extract () {
  if [ -f $1 ] ; then
    case $1 in
      *.tar.bz2)  tar xjf $1    ;;
      *.tar.gz) tar xzf $1    ;;
      *.bz2)    bunzip2 $1    ;;
      *.rar)    rar x $1    ;;
      *.gz)   gunzip $1   ;;
      *.tar)    tar xf $1   ;;
      *.tbz2)   tar xjf $1    ;;
      *.tgz)    tar xzf $1    ;;
      *.zip)    unzip $1    ;;
      *.Z)    uncompress $1 ;;
      *)      echo "'$1' cannot be extracted via extract()" ;;
    esac
  else
    echo "'$1' is not a valid file"
  fi
}

Complete hosts:

_complete_hosts () {
    COMPREPLY=()
    cur="${COMP_WORDS[COMP_CWORD]}"
    host_list=`{
        for c in /etc/ssh_config /etc/ssh/ssh_config ~/.ssh/config
        do [ -r $c ] && sed -n -e 's/^Host[[:space:]]//p' -e 's/^[[:space:]]*HostName[[:space:]]//p' $c
        done
        for k in /etc/ssh_known_hosts /etc/ssh/ssh_known_hosts ~/.ssh/known_hosts
        do [ -r $k ] && egrep -v '^[#\[]' $k|cut -f 1 -d ' '|sed -e 's/[,:].*//g'
        done
        sed -n -e 's/^[0-9][0-9\.]*//p' /etc/hosts; }|tr ' ' '\n'|grep -v '*'`
    COMPREPLY=( $(compgen -W "${host_list}" -- $cur))
    return 0
}
complete -F _complete_hosts ssh
complete -F _complete_hosts sshs
complete -F _complete_hosts host
complete -F _complete_hosts telnet
complete -F _complete_hosts ping

Complete lxc/lxd containers: (~/etc/containers must be created first)

_complete_container () {
    lxc list|grep PERSIS | awk '{print $2}'|sort|uniq >| /home/$USER/etc/containers
    COMPREPLY=()
    cur="${COMP_WORDS[COMP_CWORD]}"
    host_list=`{
        for k in /home/jonathan/etc/containers
        do [ -r $k ] && egrep -v '^[#\[]' $k|cut -f 1 -d ' '|sed -e 's/[,:].*//g'
        done
        sed -n -e 's/^[0-9][0-9\.]*//p' /home/jonathan/etc/containers; }|tr ' ' '\n'|grep -v '*'`
    COMPREPLY=( $(compgen -W "${host_list}" -- $cur))
    return 0
}
complete -F _complete_container c

c() {
        lxc exec $1 -- /bin/bash
}

proxy remote:

proxy_src_remote () {
 ssh $1@$2 -R 3128:localhost:3128
}

A docker and git alias, mainly because I can’t type and my typos are actually quite comical in terms of their use/misuse.

alias dicker='docker'
alias goit='git'

A few docker shortcuts.

# Docker stuff
# Clean stopped containers
alias cco="docker ps -a | grep "Exited" | awk '{print $1}' | xargs docker rm"
# After that, clean unused images to reclaim disk space
alias cimg="docker images | grep none | awk '{print \$3}' | xargs docker rmi"
# Finally the regular stuff just to save typing.
alias dps="docker ps -a"
alias di="docker images"
alias drmi="docker rmi"
alias drm="docker rm"

A system notification to popup when a long shell task finishes:

# Display an "alert" after running commands.  Use like so:
#   sleep 10; alert "Done sleeping"
alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//'\'')"'

Ha ha I have this one:

alias PANIC="espeak 'OH NO, the sky is falling'"

Everyone in the office just rolls their eyes

Here are a few more of my favorite aliases.

Show/hide hidden files in the macOS Finder:

alias show="defaults write com.apple.finder AppleShowAllFiles -bool true && killall Finder"
alias hide="defaults write com.apple.finder AppleShowAllFiles -bool false && killall Finder"

Limit ping to five ECHO_REQUEST packets:

alias ping='ping -c 5'

Display drives and space in human readable format:

alias drives='df -h'

Run this one in ~/ to discover what folders are using the most space:

alias usage='du -h -d1'

Colorize grep output

alias grep='grep --color=auto -n'

Clear the screen (can’t live without this one!)

alias c='clear'

That’s all, folks!
