I understand needing help and I am not running you down in any way.
When I was a newbie, a long time ago, I learned to read the man page on
commands. I learned a lot of interesting things from reading the page. As
for me I remember much more if I do the work first. Some man pages are
kind of cryptic in nature. Then I would google for what I needed, like:
How to tar a file in unix.
I keep an archive of how2xxx. They are just command lines that I used with
a few notes.
As an example I have a file named how2awk it has examples of how I did it.
Here is an example: of how2foreach
____in csh_______________________________________
#!/bin/csh
set infile = "./main_servers"
foreach abc ( `cat $infile` )
echo "---------------------"
echo "$abc"
rsh $abc 'ls /opt/SUNWexplo'
end
_____in bash_______________________________________
#!/bin/bash
## path to input file
input="lists.txt"
## Let us read a file line-by-line using while loop ##
while IFS= read -r line
do
printf 'Working on %s file...\n' "$line"
done < "$input"
I worked in csh most of the time so a lot of my examples are for csh, this
one has both csh and bash examples. They work in SUN os 4.4 through
Solaris 10 I have not tried to run the commands in Ubuntu yet but I am sure
it would.
This is just a few things to think about. I have to ask my sone a lot of
questions about how to do things in Linux. Linux is much easier to learn
than Solaris was. You can do a lot of stuff with GUIs but if you want job
security learn to do admin by the command line.

P.S.
If you keep good notes of what you did and how to do it, you will never
have to rewrite code, just modify what you already have.
