piping using tee command causing script to hang

Irfan Ahmed_1 — Thu, 14 Apr 2005 05:09:45 GMT

Hi all,

When I execute a very lengthy script file using say, following command

#./filename 2>&1 | tee output_file

Then my script in hanging at exit 1 command.
When I checked out it is tee command which is causing my program to hang.

Can anyone say the reason for this?
Is there some patch to solve this?
This problem is sporadic in nature..

Thanks
-Irfan

Hey,
does it happen with all scripts? Can you show us example of the script that fails because of tee ?

Hi

1)Look in /var/adm/syslog/syslog.log when this happens for filetable overflow messages or similar

suspect nfile

2)Otherwise you need patches

Have you tried

#./filename 2>&1 | tee -i output_file
