I have never used Linux or Unix before and have been asked to try to write a shell script given the real UNIX person found a better job. But anyway can anyone give me any help. Here is what they are asking for:

The want the script to run a "ps" command. The usage of the script is ps [search string] [ps options]

They want it to run with from 0 to 2 arguments (whatever they are).


1. no arguments ps -ef | less

2. 1 argument ps -el and pipe to grep (whatever that is)

3. 2 arguments ps-el to grep and output to less.

Can someone help me with this. I will be happy to help with any networking questions you may have (roiuters, switches, etc..)

i'm sorry, i can't really see a real question anywhere, can you be a bit more specific? you can assume everyone is fluent with ps, less, grep etc...

If I understand what you are trying to ask then your script should look like this:

#!/bin/sh

if [ $# = 2 ]
then
ps -ef | grep $1 | less
elif [ $# = 1 ]
then
ps -ef | grep $1
else
ps -ef | less
fi
