Hi all,
I've got a file of C code which for part of the file has an extra single space indent on the left hand side. To fix this I'm trying to do a regex search for "^ " and replace it with "" (ie empty string). Unfortunately, this search/replace removes all space indentation which is not really what I expect.
Any clues on getting this right? Is this a bug?
Actually having a bit of a think, it can't work since after replacing the first space with nothing it will find another space at the same place and remove it until it removes all the spaces at the start of the line before moving on to the next.
So its working right, just not what you want :-) & I'm not sure how to do it.
not sure it is "right" -- it already matched ^, so why match it again?
Because it has removed the space it matched, the so its position is back to the start of the line (which matches ^).
Yes I agree it is a possible understanding of the thing, but I'm not sure it is "the one".
BTW sed behaves the way Erik wants: sed 's/^ //g' file will only remove the first spaces of every lines, even though the option g is present.
