Hi,
Can anyone help me with the command to do the following search and replace in the following files:
Files: file1 file2 file3
Search String: "GET /thisfile?id=
Replace String: "GET /thisfile?source=1&id=
I think 'sed' can do this but I don't know the syntax.
Thanks,
Andrew

the first thing to do when you don't know something is to look it up, books, online search, you name it. Then try to do it, and if still don't get it, you can post to forums to ask. I've thought of not posting, but because today is a friday (coming to the weekends) and i am happy, i can give you a head start. :-)
[code]
sed 's/<search string>/<replacement>/g' "file"
[/code]

I should have mentioned that I did research this and I came across the sed command but it doesn't work for me. I think because of the ? and = characters in my string.
I tried the following and neither worked:
sed 's/"GET /thisfile?id=/"GET /thisfile?source=1&id=/g' file1
I also tried escaping the " and ? and =
sed 's/\"GET \/thisfile\?id\=/\"GET \/thisfile\?source\=1\&id\=/g' file1

Does 'Informix/4GL' mean you are an Informix 4GL developer? Me, too. There are not many of us left.
