Oct

Command line octal file permissions

Why?

Oct is a sample RubyGem application cloned from BasicApp. See http://github.com/robertwahler/basic_app for more information.

Oct does scratch an itch. 'Chmod' is easier to drive in octal and I can't convince 'ls -l' to output permissions in octal.

Here is an equivalent bash script

#!/bin/bash
# octal file listing

if [ "$1" == "" ]
then
  PARAM="*"
else
  PARAM="$@"
fi

for file in $PARAM
do

  if [ ! -e "$file" ]       # Check if file exists.
  then
    echo "$file does not exist."; echo
    continue                # On to next.
   fi

   stat --format='%a,%U,%G,%t %n' $file
done
