Question about writing a bash script

jeffwang66 · 11-12-2013, 02:16 PM

Hello,

I want to write a script with sed to delete all contents after '#', except if '#' appears in string "".

For example,

input file:

test #delete
"test #not delete" #delete
#delete

I want the output is:

test
"test #not delete"

Can anyone help me?

Thanks

I believe that you will find that very difficult if not impossible with sed.

Sed does not support look-ahead/look-behind so it will be very difficult to handle # inside quotes - or other places where one might occur.

You might also consider that such an expression would also remove the she-bang - #!/bin/sh - if used on a shell script which seems to be what you are trying do.
