How to change cronjob default environment

suguprathap · 08-03-2015, 10:04 AM

Hi,

root@Testing@centos~#crontab -l
* * * * * env>/tmp/cronenv

root@Testing@centos~#cat /tmp/cronenv
SHELL=/bin/sh
USER=root
PATH=/usr/bin:/bin
PWD=/root
SHLVL=1
HOME=/root
LOGNAME=root
_=/usr/bin/env

I want to change the PATH ENV to /bin:/usr/bin instead of /usr/bin:/bin. Please someone tell me how to change it commonly for all the users.

I think you should not do that, but use full path in your cronjobs. Alternatively you can write scripts to be executed by cron and you can specify PATH as you wish within those scripts.

I agree with you that we can specify PATH in cronjob itself. I just want to change the default one and that's what fulfil my requirement.

Interesting question and one that I have not considered. It appears the default path is configured in the daemon itself. I can not find any default configuration file where it is set.

Hopefully you do not have a multiple files/applications that have the same name in your path environment.

Any pam related configuration will help me to get this done ?

Did you check the link I gave?
looks like the PATH setting is hardcoded, therefore you should download the source and modify it (although I do not recommend it at all).
