How do I use sed to parse a string that includes hyphens?

Question

Input example:

foobar_1-1 1024 x 1024

Desired output

foobar_1-1

The hyphen is causing issues here. It's causing the output to be two items in the array:

foobar_1, 1

Any advice?

Answer 1

sed by default doesn't do that, it's a problem in your sed command.

if you want to manipulate strings like your example you can also use awk:

$ echo 'foobar_1-1     1024 x 1024' | awk -- '{ print $1 }'
foobar_1-1
