Question

I ve got some configuration files with hundreds of lines of data each.

I d like to begin each line (after the carriage return) with a pound sign ( # ) unless it s already beginning with a pound sign. I don t want to do a find+replace because I ve got other commented parts of the file that aren t the beginning of a line.

So for example, this:

Some data #some comment
Some more data #some other comment
Even more data
#some line comment

would turn into:

#Some data #some comment
#Some more data #some other comment
#Even more data
#some line comment

Answer 1

Use the Search -> Replace feature, but put it in Regular Expression mode and match on line beginnings:

Find What:    ^([^#].*)
Replace With: #1

This will match a line and everything in it, put that in 1, and then replace it with a # followed by what was put in 1 (the entire line).

Answer 2

Try find and replace with this regex (in regex mode):

^([^#])

and replace all with #1. (Edited with Dav s feedback - thanks!)

Answer 3

Change the Language to Perl (Alt, L, P, DOWN)
Select All (CTRL-A)
Block Comment (CTRL-Q)
Change Language back

Edit: never mind. Won t ignore already commented lines. Oh well.
