Use sed

As far as I understand sed can meet your requirements or you can even do a global replace in vi.
Open the file using vi ,type escape followed by : then type
s/Oldpath/newpath/g .This should change the path through out the file.Also note that if your path contains "/" ,then you will have to escape it using a "\"
For example:

s/old_dir1\/old_dir2\/old_dir3/new_dir1\/new_dir2\/new_dir3/g

alternately you can use sed
sed 's/old_dir1\/old_dir2\/old_dir3/new_dir1\/new_dir2\/new_dir3/g' filename >new_filename
Also if you want to pass the pathnames as argument then you can type a script containing sed which takes the path as arguments
I haven't tried the last solution,but I don't see any major problem with it.

Hope this helps
Saurabh

NWBPSET(1)							      nwbpset								NWBPSET(1)

NAME
nwbpset - Create a bindery property or set its value SYNOPSIS
nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] DESCRIPTION
nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with 'nwbpvalues -c'. See util/nwbpsecurity for an example. As another example, look at the following command line: nwbpvalues -t 1 -o supervisor -p user_defaults -c | sed '2s/.*/ME/'| sed '3s/.*/LOGIN_CONTROL/'| nwbpset With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user object 'me'. nwbpvalues -t 1 -o me -p login_control -c | sed '9s/.*/ff/'| nwbpset This command disables the user object me. Feel free to contribute other examples! nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information. Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons. OPTIONS
-h -h is used to print out a short help text. -S server server is the name of the server you want to use. -U user user is the user name to use for login. -P password password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwbpset prompts for a password. -n -n should be given if no password is required for the login. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. AUTHORS
nwbpset was written by Volker Lendecke. See the Changes file of ncpfs for other contributors. nwbpset 8/7/1996 NWBPSET(1)
