OT: Calling unix experts, Need "vi" assistance Options

[Rusty]

Sorry for the OT post.

I have a text file that I need to edit.

I need to edit every record on that file (record positions 34-37) to change whatever is in those positions (only) to a four digit number. What is currently in those positions varies dramatically.

My only text editor I have on the system is vi.

Anyone got a command I can use?

thanks,
Lawrence

(IMG:style_emoticons/default/idea.gif) Oh man, it has been a while. But even Solaris should have sed:

sed /BOA2440/BAO9999/g

Is that it? Man, I need to fire up my linux box and play around some again. First string you want to look for, second one whatever you want to change it to and the "g" for global.

I think?

you can change this to match any 4 numbers by doing something like:

/BAO[0-9]{4,4}/BAOxxxx/g

(You can probably refine this a bit - read the man page or appropriate o'reilly book)
