Advanced Search and Replace HOWTO?

[legendbb]

Hi, Gurus,

Just wondering how to script or use tool (technique) to search through multiple files for a string and duplicate the line and change part of the content in one of the duplicate.

I have a windows source, I'd like to have an automated way to scan through the code adding OS test statement and Unix version of code.

Example:

.... windows_function_call, windows_path'\' ...

automatically changes to

if(windows)
... windows_function_call, windows_path'/'...
elseif(unix)
... unix_function_call, unix_path'\'...

I can manually add those lines but it's very time consuming, and I believe there must be a smart way to do it. And it's cool to know HOWTO.

Great thanks,

[legendbb]

Thanks to google and contributor over Internet. I found my solution.

echo "elseif(unix)"
REPLACE=$(echo $line | sed 's/old/new/')
echo -e "\t$REPLACE"
else
echo $line
