Help me the shell script...

darkdream — Tue, 13 May 2003 11:02:25 GMT

The content of a file named "number" :

2210
2234
3560

I want to write my own shell script "test.sh" which translate the number to the program using the command such as :
sh test.sh 3560

This script is used to locate the rows of the number.

So anybody can give me some suggestions to write the script, thanks!

not sure what result you want?

loop to go line by line through file:
--
for i in $(cat /path/to/number)
do
#perform action
done
--

look for occurance of input arg number 1 in file:
--
grep $1 /path/to/number
echo $?
--

Later,
Bill

Hi!

As mentioned before try using the grep command.

grep 2210 /path/filename

here's a script for you -

#! /usr/bin/ksh
echo "enter the number you wish to look for"
read numb
cat number |
while read line
do
linumber=1
if [ $line = $numb ]
then
echo $linumber $numb
((linumber=$linumber+1))
elsif
((linumber=$linumber+1))
if
done

sorry - My first post had a spelling mistake.... the 2nd to last line.... "if" should be "fi" - I corrected this in my second post

Hi,

I think the -n option to grep is what you're after; it'll print the line number of any lines found.

Check the man page for grep(1) for more info. In your script you'll want to use some error checking to cope with times when the number doesn't exist in the file.

Please don't forget to assign points to people that have helped you; it helps others determine which answers are good; and helps reward people for their time and effort helping you.

regards,

Darren.

John - don't forget there's a million ways to skin the Unix cat! Actually it's more common for me to post a script and see the next post contains a really quick, neat method. :)
