Good morning,

Quick question on xargs and sed. How to change the output of the file to line by line. Pls. see the example below.

Code:

myFile.txt
server1,server2,server3,server4

I want the output to look like this. I don't need the comma and needs to read line by line.

Code:

server1
server2
server3
server4

Code:

cat /tmp/myFile.txt |xargs | sed 's / /,/g'     Not working.

You don't put a pipe after xargs. The way xargs works is it takes its first argument to be the program to run and passes the rest of the arguments to that program. You haven't given xargs any arguments at all!

Why do you need xargs here at all?

Code:

tr , \\n </tmp/myFile.txt

yes, xargs is definitely not the right tool here:

Code:

sed 's/,/\n/g' /tmp/myFile.txt
