using "cut" in perl script

armegeden · 03-05-2003, 11:06 AM

simple question; i'm using cut in a perl script to get the comment field and home directory field out of the /etc/passwd file. when i do this and store the results in variables, a newline is stuck on the end of them. this in turn makes the useradd command unhappy when i specify them in the arguments list. ie: useradd -c $name -d $home. how do i get the trailing newline character out of those variables?

thanks,
jasonp

Look at chomp

man perlfunc
see chomp

lol, thanks guys! that took care of it. the chomp function was already used elsewhere in the script, i just never realized what it did. another guy wrote it in perl, and my perl knowledge has been gotten from working on that script a little. time to buy me a book! :P 'preciate it!
