Hi All,

This command is not working in HP-UX os.

$ ps -eo pcpu,pid,user,args | sort -k1 -r | head -11
ps: illegal option -- o
usage: ps [-edaxzflP] [-u ulist] [-g glist] [-p plist] [-t tlist] [-R prmgroup] [-Z psetidlist]
Usage: sort [-AbcdfiMmnru] [-T Directory] [-tCharacter] [-y kilobytes] [-o File]
[-k Keydefinition].. [[+Position1][-Position2]].. [-z recsz] [File]..

Please help me on this command..Please suggest me the correct the syntax of the command...
Waiting for the reply..

Thanks
Jack

While waiting for the reply, you could read

Code:

man ps

In other words, you are using syntax for GNU ps, not HP UX ps.

Hi,

Could you please tell me which command can we use instead of

ps -eo ..

what is the command in HP-UX
please help me..

Thanks
Jack

Code:

In HPUX you need to use the special (but poorly documented) "UNIX95" environment variable to get the normal Berkeley "ps" syntax.
BTW. Your "sort -k1" gives a syntax error.

There are two similar ways of getting the right effect.
1) Precede the command with UNIX95=<space> . The space is important.

UNIX95= ps -eo pcpu,pid,user,args | sort -r | head -11

2) Precede the command with UNIX95=yes. The export is for completeness.

export UNIX95=yes;ps -eo pcpu,pid,user,args | sort -r | head -11

Maybe
sort -n -r

Hi,

Thanks a lot ..
It worked for me..
