# Run arbitrary commands on multiple folders or prefixed (interactive)
#
# ./icom [options] [command]
#   -c          clear before every command
#   -d          debug output
#   -f [dirs]   list folders (args for input for `ls -d`)
#
# Examples:
#   Prefix every command with `oc` (openshift executable)
#     ./icom oc
#
#   Run comands in folders matching wildcard
#     ./icom *-container
#
# Issues:
#   [command] does not work well in combinatin with `-f`
