Less is more, here are some very simple functions that I always source in to my .bashrc

Code:
# prints newest file in dir

function lat() { ls -t | head -1 ;}

# example:

$ cd Downloads/EducationalVideos

$ mpv `lat`

Code:
# adds an alias and re-sources .bashrc

# not perfect improvements are very welcome

adda(){

  al=$1

  shift 1

  echo "alias $al='${@}'" >> $HOME/.bash/alias

  . $HOME/.bashrc

}

# example:

$ adda lolello echo hello | toilet | lolcat

# adds: alias lolello='echo hello | toilet | lolcat' - to ~/.bash/alias

I also use some of the nuggets from this thread on another forum:

One of my fav:

Code:
markdown () {

    markdown_py $1 | lynx -stdin

}

Or when you mess up your tty

Code:
alias vtn='echo "X[mX(BX)0OX[?5lX7X[rX8" | tr "XO" "\033\017"'

# or

alias vtm='stty;tput reset'

And the classic extract:

Code:
extract () {

    if [ -f $1 ] ; then

    case $1 in

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

        *.tar.gz)    tar xvzf $1    ;;

        *.bz2)       bunzip2 $1     ;;

        *.rar)       unrar e $1       ;;

        *.gz)        gunzip $1      ;;

        *.tar)       tar xvf $1     ;;

        *.tbz2)      tar xvjf $1    ;;

        *.tgz)       tar xvzf $1    ;;

        *.zip)       unzip $1       ;;

        *.Z)         uncompress $1  ;;

        *.7z)        7z x $1        ;;

        *)           echo "don't know how to extract '$1'..." ;;

    esac

    else

        echo "'$1' is not a valid file!"

    fi

}

Here's a nifty music playing function from the arch wiki (one doesn't have to use "worstaudio", but I usually do just for the sake of speed - my speakers are bad enough anyway):

Code:
function mm() {

    mpv --no-video --ytdl-format=worstaudio "ytdl://ytsearch:$@"

}

And colourized man pages, from some default debian bashrc:

Code:
man() {

        env \

                LESS_TERMCAP_mb=$(printf "\e[1;31m") \

                LESS_TERMCAP_md=$(printf "\e[1;31m") \

                LESS_TERMCAP_me=$(printf "\e[0m") \

                LESS_TERMCAP_se=$(printf "\e[0m") \

                LESS_TERMCAP_so=$(printf "\e[1;44;33m") \

                LESS_TERMCAP_ue=$(printf "\e[0m") \

                LESS_TERMCAP_us=$(printf "\e[1;32m") \

                EDITOR="" \

                man "$@"

}

What's the difference between this and just regular "reset"?

Code:
stty sane   # reset line discipline

tput reset  # reset escape sequences (same as reset)
