Script to view a process tree

Craig A. Sharp — Tue, 14 Feb 2006 10:43:07 GMT

I need a script that will show child processes similar to Solaris ptree. I need to see the child processes for each parent.

Try

UNIX95=1 ps -Hef

Shalom Craig,

Just don't leave UNIX95 set all the time. It interferes with SD/UX software installation.

What is the default for UNIX95 and how to unset?

When I run the UNIX95=1 ps -Hef | grep user from the command line and then echo $UNIX95. I get ksh: UNIX95: parameter not set. So I would assume that the variable is not static.

Craig

UNIX95=1 ps -Hef

sets the environement UNIX95 only for the ps command.

You should NOT export UNIX95=1 , as this may conflict with certain commands

Ok, I will give it a try.

That works great but the user has now requested something akin to an ncurses display that is interactive.

Any ideas?

Hi Craig:

Note how I wrote the command on one line.

# UNIX95= ps -ef -H

There is a space after the equal sign and then the 'ps' command.

This arms the XPG4 (UNIX95) behavior) *only* for the duration of the command line.

Regards!

UNIX95 is an ultra-simple flag to enable XPG4 behavior in processes and libraries. It only has to be set, so value is unimportant. UNIX95= is the least number of characters needed to defined the variable. Because the shell allows you to define a variable and run a program on the same line, the subshell gets the definition, runs the process and then disappears leaving UNIX95 undefined (as it should be for normal operation).

The ps command has an enormous number of options that most admins overlook and use grep instead. UNIX95 turns on 3 very use options: -H -C and -o. Checkout the details in the man page.

compile the program attached program

cc pswalk.c -o pswalk.

#define CMD "ps -fe|grep -v STIME" /* command to get info */

I suggest you put the full path name for ps and grep in the define statement.

I have used this for many years.

Hi,
I use the pidtree script (ksh) attached.
To see the usage type pidtree ?.
It allow me to see the process family (parents and son) starting for a given pid.
I use this to be able to kill all the process tree in one shot.
Let me know if you want the killkids script as well.
HTH,
Art

Thanks Aryuro for Yor Script. It Is GREAT.

If I could, I would give you and the others points for the great service you have provided to me and others.

It is a shame that Craig has not taken the time to thank you all, by assigning points. It is free!!
