Run script error
 

I have a script run on unix and linux server , I found that if run it at shell , it works fine , but if run on crontab job , it is not work , can advise what is the different to run on shell and crontab job ? how can I fix it ? thx


the script like below

!/bin/bash

if [ `date +%d` == 18 ]
then
xx

else
yy

fi

Check the permission of the script.
What entry are you providing in the /etc/crontab entry?

Depends what you mean by 'not work' ... details please.
In any case, the most likely issue is that cron doesn't have much of an environment (eg minimal $PATH), so all cmds should be referenced by their full names eg

/bin/date

instead of just 'date'
