some vim help pelase.

i was attempting to update my yum.conf for CentOS 4 from the 4.1 to 4.2 using vim.

IIRC and if i understand vi correctly i could type the following to find and replace all 4.1 with 4.2.

:s/4.1/4.2:g

and that should swap all of the 4.1 with 4.2 globally in the file. i was getting an error pattern 4.1 not found, yet it clearly highlighted all of the 4.1 in the file. so what was i doing wrong?

I'm probably wrong, but I think you need:

Code:

:s/4.1/4.2/g

What you should have done is installed the centos-release rpm for 4.2 and that would have done it for you. To upgrade you would then just run "yum upgrade".

The vi substitution for the whole doc should be something like this:
:%s/4.1/4.2

You need to escape the dots.
. = any character, so will change 401 into 4.2

safer is:

:g/4\.1/s//4\.2/gc will ask for confirmation

or in perl:

perl -pi.bak 's/4\.1/4\.2/g' <filename>

will do it and make <filename>.bak

but reddazz is probly more correct.

:%s/4\.1/4\.2/g

This will replace the 4.1 with 4.2 globally.To ask for confirmation add c
