Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I wrote three bash files:

  1. incremental_backup
  2. full_backup
  3. execution

Now I want another bash script do the following :

if (date is the start of month 1/-/----)
then     
    invoke `full_back_up`
else
    invoke `incremental_backup`

How can I write this script?

Don't do this. Instead use two separate cron jobs to invoke your tasks.

15 5 1 * * scripts/full_back_up
15 5 2-31 * * scripts/incremental_backup

Try

if [ `date +%d` != "01" ] 
then
    incremental_backup
else
    full_backup
fi

Your answer's the same as mine, and earlier, so I deleted mine. You might want to de-capitalise the "I" in your fisrt "if", though! –  MadHatter Nov 3 '10 at 10:02
    
You should leave your answer up. There are quite a lot of duplicate answers on the site. It all adds to the community. –  Iain Nov 3 '10 at 10:14
