Exact String replacement with sed
Hi,
What should be the syntax to match and replace an exact string using sed? And not replacing any string that contain the value?
Eg.
testtest
etstetst
testetst
testtttt
etsttest
testtesttest
testtest
I only want to replace the line with exact string "testtest" with "123456"
The sed syntax I used was "sed 's/testtest/123456/g' temp1.properties"
This way it replaced testtesttest as 123456test which is not a required result.
Thanks in advance.
Regards
Eugene

I need to search and replace a particular string in a file. Only the exact match of the string should be replaced.

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
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.
