remove a char string from a command output (sed, or maybe something else)

Question

I'm trying to retrieve the distro name from the lsb_release -i output, but using

lsb_release -i | sed 's/Distributor ID: //g'

won't do the trick.

What am I doing wrong? Or maybe should I change the tool?

Answer 1

You do not have to manipulate the output if you add the -s or --short option which according to the help "show requested information in short format".

lsb_release -is

Answer 2

The character after the colon is a tab, not a space. Use

s/Distributor ID:\t//

The /g is not needed because the pattern is not repeated on the line.

You can also use much simpler

lsb_release -i | cut -f2-
