it gives me all the # lines and after
i need after # (without showing the #)
OK, now, that we finally have established what exactly you want (a files content with all comments removed), try this, which i use to strip config files before reading:
The functionality is:
s/#.*$// remove comment signs and everything after s/^[[:blank:]]*// remove leading whitespace s/[[:blank:]]*$// remove trailing whitespace /^$/d remove empty lines
Note that lines with comments are first made to empty lines by rule one (if the comment is not aligned with the beginning of line than rule 2 still reduces it to empty) and further removed by rule 4, so that they are effectively removed.
Note further, that comment signs will be removed regardless of them being in quotes, being escaped, etc., or not. If you need this functionality you cannot use regexps but have to use a parser.
You can extend this by further adding rules to filter out lines you are not interested in:
You should be able to extend this to fit your own needs.
I hope this helps.

In COBOL, a hyphen can be used in a field name and in a specific program some field names would be identical to others except a suffix was added--sometimes a suffix to a suffix was used. For example, assume I am looking for AAA, AAA-BBB, and AAA-BBB-CCC and don't want to look at AAA-BBB-CCC... (7 Replies)

How would you do vim copy line and paste at the beginning, middle, and end of another line. I know yy copies the whole line and p pastes the whole line, but on its own separate line. Sometimes I would like to copy a line to the beginning, middle, or end of another line. I would think this would be... (3 Replies)
