Chmod command in procmailrc

Hi,

is it possible to use a chmod command in procmailrc file?
I need to set a file permission if a certain matches,
and set another permission afterwards.

Thanks for a tip.

Cheers mike

Yes. Take a look at the example in man 5 procmailex that begins "Store all the messages about meetings in a folder that is in a directory that changes every month."

In that example, an arbitrary shell command is executed (mkdir $MONTHFOLDER) in the first rule, and the actual message disposition is in the second rule. You could instead supply the suitable chmod command line.

Hello,

thanks for this tip.
Still got a problem:

Code:

:0 Wic
* ? test ! -d /var/mail/test
| 'chmod 662 /var/mail'

Code:

procmail: Executing "chmod 662 /var/mail"
/bin/sh: 0: Can't open chmod 662 /var/mail
procmail: Non-zero exitcode (127) from "chmod 662 /var/mail"

Normally the shell breaks down a command line into words, by looking for spaces. The first word identifies the utility command to be called, and the remaining words are passed to it as arguments:

[0] = chmod
[1] = 662
[2] = /var/mail

Trouble is, your single quotes are escaping all the spaces, so the first word is the entire line:

[0] = chmod 662 /var/mail

The error message is trying to tell you there is no utility command with that name.

If I use double quotes I get same error message. ("chmod 662 /var/mail")
Without quotes it does not work either.
What shall I use instead?
