Remove empty lines in a text file via grep
grep, linux, text-processing
Solution
`grep . FILE`
(And if you really want to do it in sed, then: `sed -e /^$/d FILE`)
(And if you really want to do it in awk, then: `awk /./ FILE`)
Problem
`FILE`: ``` hello world foo bar ``` How can I remove all the empty new lines in this `FILE`? Output of command: `FILE`: ``` hello world foo bar ```
