Sed q?

how can I change config.version = "6" to cfg.ver = "7" in a .cfg file?

I tried

Code:

sed 's/config.version = "6"/cfg.ver  = "7"/g' /home/app/update.cfg

No luck! It's the string, that I think is killing me. It has quotes and spaces it. Any and all help is appreciated!

You'll need to use the regular expression term for a space, at the very least. This works for me... sed 's/config.version[[:space:]]=[[:space:]]"6"/cfg.ver = "7"/g' /home/app/update.cfg

A good guide to such things is the Sed FAQ, floating ubiquitousely around the net :)

I've been using GNU Sed v. 4.1.2 - taltman, does it work when you include the double square brackets...?

yes it does...i just copied it as was and didn't even think about the syntax

so both of them work for me now

ARG!! I found out what my problem was.. I had it executing in the wrong shell in my script.. D'oh! They need to add a smile for slap in head!

Thank everyone for the help!
