pstat_get_commandline()

catastro — Wed, 02 Jan 2013 03:53:38 GMT

Hi to all.
I have several servers running with HP-UX 11.11 and my command line has only capacity for 64 characters until it breaks the line and not able to see anymore the beginning of it.
I have been told that there is an enhacement that makes the command line to have 1020 characters or so, and I am looking about it and don´t find anything on how doing it.
Anyone could help me with this???

P.S.This thread has been moved from HP-UX>System Administration to HP-UX > languages- HP Forums Moderator

Shalom,

Same for all servers?

Check your TERM variable.

Are you using a standard one?

echo $TERM

stty -a
env

Look for strangeness.

Hi:

If you are referring to the command line interface 'ps' then add the '-x' switch to see up to 1024 bytes.

My understanding of this is that the underlying system call (pstat(2)) was changed to allow the ps -x functionality, but the function is not documented and is meant for HP use only.

If you have access to the ITRC knowledge base, document KBRC00006317 will tell you all you need to know.

I donÂ´t see any estrange thing in these parameters. What do you mean with the ps -x functionality?

Hi (again):

> What do you mean with the ps -x functionality?

By that I mean add that switch to your 'ps' command to enable the display of ong (larger than 64-character) commandline information for the process displayed. Up to 1024 characters are supported.

As Duncan notes, if your question concerns using 'pstat()'s PSAT_GETCOMMANDLINE, then similar extensability is not documented nor supported for it.

Regards!

Maybe an example of ps -x would help:

# ps -ef | grep [n]etfmt
root 664 663 0 13:54:35 ? 0:00 /usr/sbin/netfmt -C -F -f /var/adm/nettl.LOG000 -c /var/adm/con
# ps -efx | grep [n]etfmt
root 664 663 0 13:54:35 ? 0:00 /usr/sbin/netfmt -C -F -f /var/adm/nettl.LOG000 -c /var/adm/conslog.opts

Thanks to all of you.
It threw more light to my question with your comments and specially with the document Duncan told me to look at. I have found the solution for it.
Again thanks a lot
