How to avoid truncating in ps output ?
Hello,
This is Solaris 10 (x86)
Code:
bash-3.2# cat /etc/release
                        Solaris 10 5/09 s10x_u7wos_08 X86
           Copyright 2009 Sun Microsystems, Inc.  All Rights Reserved.
                        Use is subject to license terms.
                             Assembled 30 March 2009
bash-3.2#

I am not able to figure out, how to avoid trucating in ps output. I want full path, but is is cutting lines in the last. Even if I redirect output to a file, it is same.
I tried multiple ways, but still same
Code:
bash-3.2# /usr/ucb/ps -wwwwwaux | grep syslog-ng | egrep -v grep

Not too familiar with Solaris, I would have had proposed to make use of (man ps):
Quote:
-o format The -o option allows the output format to be specified under user control. . . . The field widths are selected by the system to be at least as wide as the header text (default or overridden value).
BUT I'm afraid you're out of luck in that special case:

Quote:
args The command with all its arguments as a string. . . The Solaris implementation limits the string to 80 bytes;
which is exactly the length of your output fields...

In Solaris the public args, as shown with /usr/bin/ps, are truncated after 80 characters.
The full args are stored in the process environment.
/usr/ucb/ps wwwaux tries to access the full args of each process. It should succeed if you own the process or if you are root.
This is a bit slowish though.

The recommended way is to use /usr/bin/ps and then pargs to only dig out the full args if needed.
Code:
/usr/bin/ps -eo pid= -o comm= | awk '$2~/syslog-ng/ { print $1 }' | xargs -l pargs

or
Code:
/usr/bin/ps -eo pid= -o args= | awk '$2~/syslog[-]ng/ { print $1 }' | xargs -l pargs

In the latter the own arguments must be excluded from args, most elegant by using a [ ] character set in the regular expression.

Seems like, this also doesn't work. Am I running it correctly ?

It seems syslog-ng overwrote/cleared its arguments array. You are out of luck.

You might use a dtrace script to intercept the arguments when the commands are exec'd and log them to a file.

Yes, I will go alternate way.
Thanks you all. I will mark this thread as solved.
