Shell script stop working
I have a strange problem.

I have the following in a cron to find files older than a day.

Code:
find /dir1/dir2/ ! -name . -prune -name "s*.txt" -type f -mtime +1 -exec echo {} \; | wc -w

It was working fine for the last few days now it suddenly stopped working. I can clearly see files in the directory that is older than a day, but the command is suddenly reporting zero. Is there something wrong with the OS?

No. The OS is fine.

Something in the envrionment changed

Code:
find /dir1/dir2/ ! -name . -prune -name "s*.txt" -type f -mtime +1 -exec echo {} \; | wc -w 2&>1 > /mypath/to/log/cron.log

read the cron.log file to find your problem.

Have you checked you're mail on the AIXbox, as cron outputs it's logging in the users mailbox.

read the cron.log file to find your problem.

The log file just shows the task executed successfully. Not errors. But I can clearly see files from June sitting in the directory. Why isn't it picking those up?

change this line after the pipe to:

Quote:
wc -w >/mypath/to/log/cron.log 2>&1


Edit: the problem is the prune command,
your first folder, dir2, is a directory, so find stops

write a script like that:

Code:
#!/usr/bin/ksh
cd /dir1/dir2/
find . ! -name . -prune -name "s*.txt" -type f -mtime +1 -exec echo {} \;

or change the command to:

Code:
find /dir1/dir2 ! -name dir2 -prune -name "s*.txt" -type f -mtime +1 -exec echo {} \;

from the man page of find:

Quote:
-prune
Always evaluates to the value True. Stops the descent of the current path name if it is a directory. If the -depth flag is specified, the -prune flag is ignored.

Ok.

The change you recommended worked but why? It was working all along just fine as it was, then suddenly stopped. When I make the change you suggested, it's working agin. How strange.
