n-1 a possibility?

jsheffie · 05-16-2006, 12:00 PM

Hi,

I am trying write a bash shell script. In this script is a portion that reads lines from an external file using:

for i in `cat $FILEPATH`
do

I am having a little trouble because, even though all items from the file are list in a preview page, only the first line gets implemented.

Does anyone know of a way to do a sort of n - 1 setup where a script will read the first line, apply the second command, re-read the file but ignore the first line and apply the second command... re-read the file but ignore the nth line?

Or is there maybe another option for applying multiple entries to shell commands?

thanks,

you really need to explain what you want to do better ... not got a clue what you are after...

Guessing a bit here what it actually is you want to do.. but try this:

Suppose you have a file called "file.txt" with this content:

Code:

one: the first line
two: the second line
three: the third line
four: the forth line

Then try this (bash) script:

Code:

#!/bin/bash
while read i ; do
    echo "==> $i"
done <file.txt

HKO... I will try that first thing in the morning...

Thanks for all the help,
