Yes, You could do it in the GIMP or even use Inkscape, but the command line is so much easier.

This is a new version of a previous command fixing some things complained about.

crontab -l | sed -e '$G;$s-$-'"$CRON_MINS $CRON_HOUR"' * * * /usr/bin/command >/dev/null 2>&1-' | crontab -

I needed to add a line to my crontab from within a script and didn't want to have to write my own temporary file.

You may find you need to reload the crond after this to make the change take effect.

e.g.:

if [ -x /sbin/service ]

then

/sbin/service crond reload

else

CRON_PID=`ps -furoot | awk '/[^a-z]cron(d)?$/{print $2}'`

if [ -n "$CRON_PID" ]

then

kill -HUP $CRON_PID

fi

fi

The reason I had CRON_HOUR and CRON_MINS instead of numbers is that I wanted to generate a random time between midnight & 6AM to run the job, which I did with:

CRON_HOUR=`/usr/bin/perl -e 'printf "%02d\n", int(rand(6))'` CRON_MINS=`/usr/bin/perl -e 'printf "%02d\n", int(rand(60));'`

This command allow you quick find any executable by keyword(s) in your system.

NOTE: Sometime this command will output like this:

`hello.py.launch': No such file or directory

this is normal behaviour

This version uses the indent C formatting utility. Doesn't appear to be included with ubuntu. But CentOS and MacOS have it.
