find/change text in VI


I'm trying to figure out how to replace a sentence within a short bash script I wrote, but I can't get the syntax right. I'm hoping someone here can help.

If I have a file that I want to change a sentence into just one word, what command would I use? For example:

# Bash File1
ssh machine1 /etc/rc.d/init.d/gmond restart
ssh machine2 /etc/rc.d/init.d/gmond restart
ssh machine3 /etc/rc.d/init.d/gmond restart
ssh machine4 /etc/rc.d/init.d/gmond restart
ssh machine5 /etc/rc.d/init.d/gmond restart

What I want it to look like:

# Bash File2
ssh machine1 halt
ssh machine2 halt
ssh machine3 halt
ssh machine4 halt
ssh machine5 halt

I thought the command was something like

:%s/[/etc/rc.d/init.d/gmond]/halt/g

But that doesn't work right. Is there an easy way to make these changes? As always, thanks for your help.

:x,ys/[/etc/rc.d/init.d/gmond]/halt/g where x = the first line to start on and y equals the last line to consider.

so if you wanted to run the search and replace on lines 10-100 you'd do :10,100s.......

Quite close :)

Try
Code:
:%s/\/etc\/rc.d\/init.d\/gmond/halt/g
instead ...


The [] doesn't work because that makes your search
look for characters out of that selection, not for that
group...


Cheers,
Tink

And if u don't know the line #s, use something like

:s/<old>/<new>/#

where # is the number of lines.
