Problem in log generation in USS

[Sandeep Dwivedi]

When i am trying to run the same script on USS which i ran successfully on UNIX
I am getting an error.

This is the part of the script which is giving an error. I want the output to be on the screen and also a log should be generated.

tee ../logs/build_bo_jar.log >/dev/tty |&
exec 2>&p 1>&2

Error is
exie 19: FSUM7341 bad file descriptor "p"
zOS 1.6 [/indus2/icapi/fw600/scripts]

Thanks in Adwance

what is USS?

[Sandeep Dwivedi]

USS is unix system services.
UNIX System Services allows UNIX applications from other platforms to run on IBM mainframes.
USS is a certified UNIX implementation (XPG4 UNIX 95) optimized for mainframe architecture.
Through integration with the rest of z/OS, additional time share option (TSO) commands are available alongside the usual UNIX services, making it possible to process UNIX files using ISPF. Extensions in JCL make it possible to use these files in batch processing.

>USS is a certified UNIX implementation (XPG4 UNIX 95)

I can't see &p (co-process) as being valid in UNIX95 through UNIX2003. So it seems that USS doesn't have to support it.

I would also think that would make |& useless.
(Right, I don't see it in UNIX2003.)

Thanks
is there any other way of generating a log in USS?

[Rasheed Tamton]

This will generate the output on the screen as well as to a file (plus the error message, if any).

cat ../logs/build_bo_jar.log 2>&1 |tee jarlog.log



Regards.

>Rasheed: cat ../logs/build_bo_jar.log 2>&1 |tee jarlog.log

Unfortunately I believe build_bo_jar.log IS the log file. Of course that leads to a solution, output to the log file, then do a tail -f on that log file. Or a cat(1) when done.

Thanks for your advices. I tried them but
This solution is not working.
It is just creating build_bo_jar.log and jarlog.log of 0 size.

[Dennis Handly]

I'm lost, you'll need to show us what you are currently doing. Perhaps a script fragment with some echos showing the output you want to track.

[Sandeep Dwivedi]

This is the script wch i am running in USS,
Since its an interactive script (accepts input from user) so the log generation become more complex.
I want to print output on the console as well as the same output should go inside a log file.
Please suggest me a method

[Dennis Handly]

Ok, thinking about it, you can of course send all of your output to a new file. Then at the end, copy that output to your logfile, then to the tty. Fortunately you have a nice function exit_process where you can do this clean up.

(Add somewhere at the top)
TMP=/var/tmp/foo.log # add $$ if you have multiple occurrences
exec 3>&1 # save old stdout
exec 4>&2 # save old stderr, needed?
exec > $TMP 2>&1 # redirect both to $TMP

And in exit_process: (I'm sending to stdout vs /dev/tty, you can change that.)

# Copy from $TMP to log and to stdout:
cat $TMP >> ../logs/build_bo_jar.log
cat $TMP 1>&3
rm -f $TMP
