Linux shell script help?

[Roo]

Dunno if anyone can help me but its worth a go lol.

Basically I need to find a command to show just the PID's and their status' (JUST these two things, I know you can put 'ls -a' and that will show everything).

I know its a long shot, but dunno if anyone here is a whizz with Linux or somet.

Plus does anybody know of any decent sites where I can find shell commands etc.

Thanks in advance.

Yeah try using the help pages. Its man man in the console for the help page. Ok my thought is you might be able to use grep or fgrep with the right paramerters to go through your ls -a and just give u PID's. I'm a noob on linux so i'm not sure. Good luck lol

[SpArKy]

% ps -o pid -o stat
PID STAT
4351 S
7593 R

Hope thats what u meant?

New question guys,

Find the directory from root (/) where all of the programs are which you make use of to
manipulate the tree structure (cd, ls, mv, cp, and so on). What is the directory’s name? Why
does it have this name? Verify that this directory is in the path string which the system searches
through to find executable files and explain what you have found.

I have answered it all apart from the last part. Can anybody help me ... need a reply by 2moro morning if possible lol.

[/dev/null]

%> echo $PATH

[Roo]

%> echo $PATH

Cheers for reply John.

So will it be alright to just type that into the terminal or do I need to add any commands after it?

[/dev/null]

I'd personally just type it in. you'll get an output similar to this:

/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/java/j2sdk1.4.2_06/bin:/opt/teaching/bin:/opt/scripts:/opt/common/bin:/home/oracle/sbin:/usr/games:/opt/spark/linux:.

One option I guess would be to pipe it to grep or sed and then check whether it contains what you want there, however what's the point - way too much overkill unless you have a path variable that's longer than your arm, lol.
