problem in replacing string in vi editor

texasj · 07-23-2011, 12:56 AM

I tried to replace a windows directory structure to linux directory structure in vi editor but it's giving me error "E488 trailing characters" (O.S is redhat 5)

F:\oracle\app\oradata

I want to replace it to

/u002/app/oracle

I have been searching this for 2 days & didn't get any solution.! Can any body know how to replace it?
Thanks in advance......!

Hi,

The back slashes in the original path are special and so are the forward slashes in the replace part.

Try this:

Code:

:s%F:\\oracle\\app\\oradata%/u002/app/oracle%

Hope this helps.

Hello texasj,

for me with vim this works

Code:

:%s/F:\\oracle\\app\\oradata/\/u002\/app\/oracle/g

Explanation:
% search the whole file
s substitute
\\ a backslash
\/ a slash in Linux/Unix
g replace every occurence in the whole line (without g it replaces only the first one)

That doesn't seem to work...

1) You have a double backslash before the F:
2) The back-referencing doesn't replace the backslash between app and oradata (it should also be replaced by something else).

EDIT: The above code has been changed (see post #5).

Sorry, you're right, 1) was a mistake, 2) I did not see that, I've changed the codeline in my above post.

yes, he has

, maybe he tries some solutions with sed, awk or perl, the problem seems to be somewhat educating.

Thanks a bundle DRUUNA & MARKUSH i able to solve the problem with your solutions, sorry for the late reply ! both of you certainly made my day as i was totally frustrated due to this problem!
Thaaaaaaaaanks a bunnnnnndle...!

Here how you solved this problem:

1. First solution [druuna]
:s%F:\\oracle\\app\\oradata%/u002/app/oracle%

-->This solution is good when replacing only one line.

#by mistake I didn't mentioned that there are more than one lines to be replaced.

2. Second solution [markus]
:%s/F:\\oracle\\app\\oradata/\/u002\/app\/oracle/g

-->Replaces all the lines in the file

Thanks again for educating me...!
