Need help in writing simple shell script to format names

naren_0101bits · 08-14-2007, 02:31 AM

Hi All, I just started learning shell scripts.

There is one text file names.txt having names seperated by comma like

Krishna,Pavana,Aravind,Alpha

How can i write a script using for loop to get those names output in seperate lines as

Krishna
Pavana
Aravind
Alpha

Use cut command also

Thanks in advance.

This wouldn't be homework would it? I'd just do 'sed 's/,/\n/g' names.txt' with GNU sed.

use the built in IFS variable. I use ksh korn shell, so this is for korn.

Code:

#!/bin/ksh

IFS=","  #the IFS you can set to whatever you want your file to be delimited (separated) by.  IFS works in conjuction with the "read" routine in this case.

while read name1 name2 name3 name4 name5
do

echo $name1
echo $name2
echo $name3

done < names.txt

exit 0
