Reed said on Tue, Apr 02, 2002 at 11:35:25PM -0500: In cases where there was an even wider divergence between the BSD and System V commands (the ps(1) command being the most infamous example), you may find the BSD version in /usr/ucb (this is analogous to but reversed from the old SunOS case, where the System V versions were in /usr/5bin). Don't assume, however, that BSD style necessarily is 100% the same as GNU style. ps being the example, yet again; the w option doesn't show as much stuff as you can get with two ws on GNU ps. msg26577/pgp0.pgp Description: PGP signature

You can also put two 'w's on /usr/ucb/ps and get the full command line of every process, but the point is a good one. The GNU/Linux versions of commands are neither System V nor BSD, but a separate animal inspired to various degrees by each of the traditions. -- Mark REED| CNN Internet Technology 1 CNN Center Rm SW0831G | [EMAIL PROTECTED] Atlanta, GA 30348 USA | +1 404 827 4754 -- Military intelligence is a contradiction in terms. -- Groucho Marx

We ran into this problem when one of our developers wrote an application on Linux that did a ps and looked for a string, when the process in question was in an extremely long path and was run with the full path name. When he ported it to Solaris, it wouldn't work, even with /usr/ucb/ps, because of the cutoff. I suggested we install GNU ps, but nobody in management wanted to hear that. msg26582/pgp0.pgp Description: PGP signature

The first kind wouldn't recognize a server if it reached out and smacked them. The second species wants to sound like they know what's going on, but really has no idea what's going on, so when I suggest something, they say Hrmm. Let me think about it. Then they come back a few hours later and say I think you're on to something. Go for it. we install GNU stuff in /usr/local since Solaris doesn't have anything in there by default. Then to each their own, as they set up their shell. You have /usr/xpg4/bin, /usr/bin, /usr/local/bin, as you prefer. Cheers, -Tim -- He's God. He's flighty.

.. I end up having to work around Solaris'
braindamage in a number of ways.
For instance, on every OTHER OS (including
pre-Solaris-renaming SunOS, HP/UX 9, NeXT Mach),
I can use id -u to get the EUID. Solaris?
setenv EUID `id | sed s/[a-z\(\)\=]//g | awk '{print $1}'`
Yippie. Yeah, I could use cut(1) and do
it a bit more efficiently probably, but...
won't sed suffice? let's see..
$ uname -a
SunOS ritz 5.8 Generic_108528-13 sun4u sparc
$ id
uid=10077(guckes) gid=10025(emailer) groups=10025(emailer),10365(hacker),..
so we just need the first number before the first space.
easy:
$ id | sed -e 's/^uid=\([0-9][0-9]*\).*/\1/'`
10077
works for me
of course this is much easier with the ZShell:
$ echo $EUID
10077
ZShell rules! :-)

Reed wrote: /usr/xpg4/bin/id -u To expand upon this: When SunOS becamse Solaris, its base moved from BSD (Berkeley's UNIX-based OS) to System V (official UNIX from ATT). For compatibility with System V applications (and with the POSIX standard), they had to give all of the standard commands in /bin (or /usr/bin) the System V semantics. However, the older behavior was in many cases superior, and those commands have been retained in /usr/xpg4. I tend to prefer the XPG version of most commands, so I have /usr/xpg4 before /usr/bin in my PATH. In cases where there was an even wider divergence between the BSD and System V commands (the ps(1) command being the most infamous example), you may find the BSD version in /usr/ucb (this is analogous to but reversed from the old SunOS case, where the System V versions were in /usr/5bin). Note that not all Solaris installs have these packages; I've found that more have /usr/xpg4 than /usr/ucb. -- Mark REED| CNN Internet Technology 1 CNN Center Rm SW0831G | [EMAIL PROTECTED] Atlanta, GA 30348 USA | +1 404 827 4754 -- Now I lay me down to sleep I pray the double lock will keep; May no brick through the window break, And, no one rob me till I awake.
