I wrote this `hr` command because sometimes having a separator in your terminal helps you find things in the output of your previous commands

hr.bash

#!/usr/bin/env bash

usage() { echo "Usage: hr [-h] [-c <CHAR (defaults to '=')>] [<LINES (defaults to 1)>]" 1>&2; exit 1; }

CHAR='='

while getopts "h c:" ARG; do
  case $ARG in
    c)
      CHAR="$OPTARG"
      ;;
    h | *) # Display help.
      usage
      exit 0
      ;;
  esac
done

LINES=${@:$OPTIND:1}
# ARG2=${@:$OPTIND+1:1}

LINE_CONTENT="$(printf '%*s' "${COLUMNS:-$(tput cols)}" '' | tr ' ' "$CHAR")"

for i in $(seq ${LINES:-1}); do
    echo "$LINE_CONTENT"
done
