Hi all,

Can someone provide me the information regarding the UNIX95 utiliy.

Thanks,

Shalom,

You set UNIX95=1 and you get some enhanced output from the ps command.

Example:

export UNIX95=1

CL="ps -a -o pid,sz,vsz,args -C $FILTER | sort -nr -k 2,3| head -$NUM"



Don't set it universally, it will prevent you from unsharing HP depot software and patches.

Hi:

This is not a utility but rather an environmental option (variable) that controls how certain commands function. You will find that the manpages refer to it as "XPG4" also. In the case of 'ps' setting UNIX95 behavior allows custom formatted output. For example:

# UNIX95= ps -o pid,vsz,comm

...would show my process's pid, virtual size, and basename.

The UNIX95 option in the above example is set _only_ for the duration of the command line by writting it as shown --- whitespace trailing the "=" character before the command ('ps').

Do not globally set UNIX95 in your scripts or profiles. While some commands ignore it, others change their behavior in subtle ways. Consult the manpages on a command-by-command basis before using it.

Regards!

UNIX95 is not a utility but rather an environment variable. When it is defined it asserts the XPG4 standards (X/Open Portability Guide) behavior in a number of UNIX commands most notably the ps command.
