vi question

[subhashni]

Hello ,
Is there any easy way to replace bunch of word in file in vi mode. For example in a file i have strings as "x123" ,"y123" ,"4123" etc.
I would like to change these strings as "0123".Please help.
Thanks

Hi,

Try this:

:%s/.123/0123/g

You can use global replacement method in vi mode
for Ex: if you want to replace x123 as 0123 use this way

:1,$s/x123/0123/g

How about using sed:

sed 's/*123/0123/g' filename

I think that will do it.

The command to use would be:

:1,$s/[1-9a-zA-Z]123/0123/g

The above will replace any string that starts with a number other than 0 or an upper or lower case letter followed by 123 (1123,a123,D123, etc) with 0123 and will do it for all occurrences.

Note that "." represents any single character, so enter this vi global replace command:
:/.123/s//0123/g

OK, I'll take that back. Why don't I test these things before publicly making a fool of myself? Arghh!

I am attaching a perl script that does this work with system calls.

Makes it a bit easier.

Its pretty wasy to read code.
