Add 'G1' to the start of each line.
- 
 Sorry noob here… I am writing a G-Code program for my home made cnc. My thing is I need to add ‘G1’ to the start of each line and as I have over 12,000 lines I don’t want to do each line in turn… 
 Is there a way to use find and replace to do this automatically?Any help would be great.

 Hello, @cnc-builder Elementary task with regular expressions, indeed !! - 
Move back to the very beginning of the file to change ( Ctrl + Origin)
- 
Open the Find/Replace dialog ( Ctrl + H)
- 
Type ^, in the Find what: box
- 
Type G1, in the Replace with: box
- 
Choose the Regular expression search mode 
- 
Click on the Replace All button 
 Et voilà ! Notes : - 
The ^character is the symbol, meaning “beginning of line”, in regular expressions
- 
If you prefer to separate the string G1 from the rest of text, you may, either, add a space character after G1 or the symbol \t, for a tabulation character
 Best regards, guy038 P.S. : For newby people, about regular expressions concept and syntax, begin with that article, in N++ Wiki : http://docs.notepad-plus-plus.org/index.php/Regular_Expressions In addition, you’ll find good documentation, about the Boost C++ Regex library, v1.55.0 ( similar to the PERL Regular Common Expressions, v1.48.0 ), used by Notepad++, since its6.0version, at the TWO addresses below :http://www.boost.org/doc/libs/1_48_0/libs/regex/doc/html/boost_regex/syntax/perl_syntax.html http://www.boost.org/doc/libs/1_48_0/libs/regex/doc/html/boost_regex/format/boost_format_syntax.html - 
The FIRST link explains the syntax, of regular expressions, in the SEARCH part 
- 
The SECOND link explains the syntax, of regular expressions, in the REPLACEMENT part 
 
 You may, also, look for valuable informations, on the sites, below : http://www.regular-expressions.info http://perldoc.perl.org/perlre.html Be aware that, as any documentation, it may contain some errors ! Anyway, if you detected one, that’s good news : you’re improving ;-))
