Following on from my tip the other day about using Notepad++ to remove certain lines, I thought I would follow up with a nice one liner you can do the same using Perl.
In this example you can see the before and after of the text file
MacBook-Air:~$ cat test.txt #Hello Goodbye #Test Test1 MacBook-Air:~ $ perl -i -nle 'print if !/#/' test.txt MacBook-Air:~ $ cat test.txt Goodbye Test1
Nice and easy, hope this can help you out as well. Do you have any more suggestions or tips like this, please get in contact or leave a comment below.
