crontab output redirection

Christine Roberts — Thu, 11 May 2000 03:42:33 GMT

I have unsuccessfully tried to redirect output from a "tar" backup job in my crontab to a file using the following in my root crontab:

0 2 * * * tar cv "files" > /tmp/logfile

Output always goes to the root mail account.

I have also found that I cannot redirect any output from the "tar" command.

HP-UX 10.20

Please advise.

You also need to redirect the error out. Using the example you gave only the standard out would go to the logfile and any error messages would go to your mail.

Use the following syntax;

0 2 * * * tar cv "files" > /tmp/logfile 2>&1

This means also send error out (2) to standard out (1).

use the standard error redirect in your crontab.
i.e crontab command 2> /tmp/out
or crontab command 2>> /tmp/out if you want to append to the file.

Pardon the pun but 'tar'.

I had tried using stderr redirection though
I had been placing it as follows

tar cv 2>&1 > /tmp/logfile

ie: the cart before the horse.

Thanks
