Functions

`colors` - Display colors

colors() {
    local fgc bgc vals seq0

    printf "Color escapes are %s\n" '\e[${value};...;${value}m'
    printf "Values 30..37 are \e[33mforeground colors\e[m\n"
    printf "Values 40..47 are \e[43mbackground colors\e[m\n"
    printf "Value  1 gives a  \e[1mbold-faced look\e[m\n\n"

    # foreground colors
    for fgc in {30..37}; do
        # background colors
        for bgc in {40..47}; do
            fgc=${fgc#37} # white
            bgc=${bgc#40} # black

            vals="${fgc:+$fgc;}${bgc}"
            vals=${vals%%;}

            seq0="${vals:+\e[${vals}m}"
            printf "  %-9s" "${seq0:-(default)}"
            printf " ${seq0}TEXT\e[m"
            printf " \e[${vals:+${vals+$vals;}}1mBOLD\e[m"
        done
        echo; echo
    done
}

`tre` - Tree display

tre is a shorthand for tree with hidden files and color enabled, ignoring the .git directory, listing directories first. The output gets piped into less with options to preserve color and line numbers, unless the output is small enough for one screen.

function tre() {
    tree -aC -I '.git|node_modules|bower_components' --dirsfirst "$@" | less -FRNX;
}

`mkd` - Create a new directory and enter it

function mkd() {
    mkdir -p "$@" && cd "$_";
}

`fs` - Filesize of directory

function fs() {
    if du -b /dev/null > /dev/null 2>&1; then
        local arg=-sbh;
    else
        local arg=-sh;
    fi
    if [[ -n "$@" ]]; then
        du $arg -- "$@";
    else
        du $arg .[^.]* ./*;
    fi;
}

`nullify` - Redirect both standard output and standard error, as well as sending to background

function nullify() {
    "$@" >/dev/null 2>&1
}

Bash History

Undocumented feature which sets the size to "unlimited". http://stackoverflow.com/questions/9457233/unlimited-bash-history

# Huge history. Doesn't appear to slow things down, so why not?
HISTSIZE=500000
HISTFILESIZE=100000

# Avoid duplicate entries
HISTCONTROL="erasedups:ignoreboth"

# Don't record some commands
export HISTIGNORE="&:[ ]*:exit:ls:bg:fg:history:clear"

# Use standard ISO 8601 timestamp
# %F equivalent to %Y-%m-%d
# %T equivalent to %H:%M:%S (24-hours format)
HISTTIMEFORMAT='%F %T '

Change the file location because certain bash sessions truncate .bash_history file upon close. http://superuser.com/questions/575479/bash-history-truncated-to-500-lines-on-each-login
