# barsh: a minimal bash progress bar

barsh is a 7-lines implementation of a progress bar in bash, using bg/fg color

ANSI escape sequences instead of block characters. Use it directly as a

standalone tool on your shell, source it and use it on your scripts, or just

admire it in all its glory

```bash

function barsh {

  [[ $# -lt 2 ]] && return 1

  local val=$1; local bas=$2; local txt=$3; local wid=$4;

  [[ -z $wid ]] && { [[ -z $txt ]] && wid=$bas || wid=${#txt} ; }

  [[ -z $txt ]] && txt="$(printf '%*s' "$wid" '')"

  [[ $wid -gt ${#txt} ]] && txt=$txt$(printf '%*s' $((${#txt} - wid)) '')

  local per=$(( (wid * val) / bas ))

  printf "\033[7m%s\033[27m%s" "${txt:0:$per}" "${txt:$per:$((wid-per))}"

}

```
