Why Git adds - and + to all of my code?

Question

Sometimes for example I change a word in line 100 and delete last 4 lines. When I run "git diff" It shows a log which has a -(minus) and +(plus) before all lines whereas I changed only mentioned lines.
I thought it may be due to changing number of all lines but when I saw the changes again I didn't see any change to line numbers.

so what cause this?

Which text editor are you using? Perhaps it changed line endings between Unix/DOS. (i.e. LF to CR+LF)

That's just formatting to show what lines have been changed (added/removed/etc). Those +s and -s are not actually in your files.

Ahh ok. Yeah its probably a CRLF mismatch. Check your autocrlf settings. – Frank Schwieterman Oct 01 '10 at 18:40
Thanks.but do you know how do I change autocrlf settings? – Nick.h Oct 01 '10 at 18:59
I'm afraid I haven't wrapped my head around the best thing to do with the AutoCRLF setting. Here's some background reading: http://stackoverflow.com/questions/2016673/definitive-recommendation-for-git-autocrlf-settings – Frank Schwieterman Oct 01 '10 at 20:19
My understanding is that you're better off getting your editor to do the right thing and not having to mess with autocrlf. – bstpierre Oct 02 '10 at 00:57
