Does anyone have a suggestion on turning c:\windows into c:\\windows?
I don't have a Windows PC to hand ATM, but the following works in Fedora
bash:
#!/usr/bin/bash
TEST=$(echo c:\windows | sed -e s;;;g)
echo ${TEST}
Dave.

Thanks, -- cyg Simple The combination of shell globbing and sed metacharacters, with appropriate escaping, is rather difficult, and nearly impossible to read. I would suggest using the 'sed -f file' so you can completely eliminate any shell processing. The file should contain the string 's/\\//', without the quotes ;) Of course, if you want your script to be in a single file, this won't work, so one of the other responders answers may be more suitable. FYI, I would suggest not using the dot as a pattern separator, it could be confusing to novice readers, and also removes it as a pattern match character.

Never ever use odd numbers of backslashes, when dealing with backslashes! ;^
\\ is the character backslash, doubled for each layer of interpretation it
has to pass thru before it gets to where it's going.
