Well the most used, and first thing i add when i get to a new system is: rcbash='~/.bashrc' alias src="source $rcbash" alias vrc="vim $rcbash" alias vimo="vim -O" # vsplit files And then, a little snippet which made my "bashrc" less repetitive when it comes to folder aliases. gr4_folderize() { # creates aliases and variables for a path # # $1 = used abbreviation # $2 = folder path # # gr4_folderize "esp32" "/srv/dd/esp32" # creates aliases `cdesp32`, `lsesp32` and `diresp32` env # ${param:?word} writes `word` to stdout when param is unset or null local abbrev="${1:?No abbreviation alias.}" local folder="${2:?No directory to folderize.}" export dir${abbrev}="$folder" which > /dev/null 2>&1 cd${abbrev} || alias cd${abbrev}="cd $folder" which > /dev/null 2>&1 ls${abbrev} || alias lll${abbrev}o="lla $folder" }

Plus `ask_yes` if you want to ask if user is sure. ask_yes () { read -r -p "$1 = Are you sure? [y/N] " response if [[ "$response" =~ ^([yY][eE][sS]|[yY])+$ ]] then return 0 # true = 0 else return 1 # false = 1 fi } Plus `countdown timer` to make user think about what he has done, before he does it. (Code is a mess cause i used some snippet then created another from it) countdown_str () { # countdown "00:01:00" # = hh:mm:ss IFS=: set -- $* secs=$(( ${1#0} * 3600 + ${2#0} * 60 + ${3#0} )) while [ $secs -gt 0 ] do sleep 1 & printf "\r%02d:%02d:%02d" $((secs/3600)) $(( (secs/60)%60)) $((secs%60)) secs=$(( $secs - 1 )) wait done echo } countdown_5 () { countdown 5 2>/dev/null } countdown () { secs=${1:-"00"} mins=${2:-"00"} hours=${3:-"00"} chars=$(printf "%02d:%02d:%02d" $hours $mins $secs) echo "Countdown from $chars" countdown_str $chars 2>/dev/null }
