:'(  who can help me po pls...... I need to write a unix script (Bourne shell compatible)

What will be the purpose of the bash script?
I may be able to help.

For a start here is a intro HOWTO on bash scripting: http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html

hmmm my text file po dpat irun 1st column first name 2nd column last name 3rd column id # 4th column department,,,,, tas pag ni run dapat gagawa ka ng file na lalabas alphabetical order example ung result aa.txt for last name ending with a..... ang prob ko po dapat di lalabas ung mga files na walang names sa listahan like x ganun eh lumalabas padin kahit gamitan ng wc -l sa script.....like this (43 Apr  6 14:00 emp-hh.txt
 0 Apr  6 14:00 emp-ii.txt
42 Apr  6 14:00 emp-jj.txt)

dpat la si emp-ii.txt .......

... alphabetical order example ung result aa.txt for last name ending with a.....

Ending or STARTING with 'a'?

Anyway, here is the script which ignores the 0 lines file in the list:
wc -l * | awk '{ if ($1!=0) print $0 }'

This uses awk and is very common tool in Unix scripting.

here's how to find the last letter of a string, save this file as "lastchar" file

Code:

#!/bin/bash
echo "input string = "$1
echo "length of string = "${#1}
echo $1 | cut --characters=${#1}

-bash-3.2$ chmod +x ./lastchar
-bash-3.2$ ./lastchar elephant
input string = elephant
length of string = 8
t
-bash-3.2$ ./lastchar "elephant mouse"
input string = elephant mouse
length of string = 14
e
-bash-3.2$

it's the code "${#1}" that returns the length of the input string in variable $1.
