Edit file


Howdy!

I would like to make a script that can change a line in a file.. commenting
out a line in a java source file to be precise.

I would like to look for this line:
  import visualiser.HostIDVPatcher;
and edit it to this:
  // import visualiser.HostIDVPatcher;

Can I do this?

I tried using sed with this line:

cat visualiser/PositionData.java | s/import
visualiser.HostIDVPatcher;/\/\/import visualiser.HostIDVPatcher;/ | out.txt

and this was what I got:

<r;/\/\/import visualiser.HostIDVPatcher;/ | out.txt
BASH: s/import: No such file or directory
BASH: ///import: No such file or directory
BASH: /: is a directory
BASH: out.txt: command not found

Thanks for any help!

Rob
