[ncl-talk] execute a ncl script in crontab [SEC=UNCLASSIFIED]

[Griffith Young]

I realise that this has been answered already, but I typed it and I may as well share it.

When you run a command from cron, you will have basic "sh" shell.

When you run from the terminal, you will have "bash" and you will probably have called .bashrc and .bash_profile.  These will have added to you PATH environment variable and other environment variables that NCL uses.

Often the simplest work-around is to create a script just for cron to call that will "source" your .bashrc (possible, but not recommended), or that sets the important environment variables for you (PATH, 
NCL_ROOT, NCARG_ROOT, ...)

Another reason that your script may not work is that you start in your home directory when you run from cron.

Happy hunting.

Regards, Griff.

Dear people,

I execute a ncl file by terminal, (ncl filename.ncl)   but when I launch it by crontab it doesn't run...crontab ignores it.  I use bash script in crontab without problems...

Thank you in advance
