[Q] TEE does NOT put screen messages to log file???
|
|
|
| We are doing batch script for backup. The server is IBM RS/6000 AIX 4.3.3
version. The script supportly should show backup messages on monitor screen and
also on log file. I test the script and look like "tee" does NOT put screen
messages to file.
my backup script are:
for i in `cat /home/backup/lvdir`
do
/usr/sbin/backup -0 -u -f /dev/rmt1.1 $i |tee -a /tmp/backup.log
echo "* \n" >>/tmp/backup.log
echo "* End of backup file system: $i \n" >>/tmp/backup.log
echo "********************************** \n" >>/tmp/backup.log
echo "* \n" >>/tmp/backup.log
done
Any ideal?
Thanks.

Please do not multi-post. Your question has been answered in
comp.unix.shell.
If you feel you must post a question in more than one group,
cross-post (i.e., put all the newsgroups in a comma-separated list
on the Newsgroups: line in the header.

Two possibilities:
1) The messages you're not seeing in the file were written to stderr,
but you're only piping stdout. Try changing it to:
/usr/sbin/backup -0 -u -f /dev/rmt1.1 $i 2>&1 |tee -a /tmp/backup.log
2) Backup is writing messages directly to /dev/tty, not stdout. Expect
may come with a script that will capture this for you.
