Examples--Displaying Information About Processes
The following example shows how to use process tool commands to display more information about an lpsched process. First the /usr/proc/bin path is defined to avoid typing
long process tool commands. Next, the identification number for lpsched is obtained.
Finally, output from three process tool commands is shown.
[Adds the /usr/proc/bin directory to
the PATH variable. ] # PATH=$PATH:/usr/proc/bin
# export PATH
[Obtains the process identification number for lpsched. ] # ps -e | grep lpsched
191 ? 0:00 /usr/lib/lpsched
[Displays the current working directory for lpsched.] # pwdx 191
191: /
[ Displays the process tree containing lpsched. ] # ptree 191
183 /usr/lib/lpsched
[Displays fstat and fcntl
information. ] # pfiles 191
210: /usr/lib/lpsched

The following example shows output from the pwait command, which waits until
a process terminates, then displays information about what happened. The following example shows output
from the pwait command after a Command Tool window was exited.
$ ps -e | grep cmdtool
273 console 0:01 cmdtool
277 console 0:01 cmdtool
281 console 0:01 cmdtool
$ pwait -v 281
281: terminated, wait status 0x0000
