Hi all,

The scenario is like this: i have one file which contains some particular paths, now my aim is to make changes in this file so that i can change the path in that file.. eg:

file1.txt:

ABC
-p /home/user/a/b/v23.9/library -l /home/user/a/b/ABC/v23.9 test.exe
DEF
-r v23.9 /c/d/f -p /home/user/a/b/v23.9/library -l /home/user/a/b/ABC/v23.9 test.exe

end of file1.txt

now i want to change only this 'v23.9' to 'abcde' that to only in both the paths.
I tried using "tr" but it changes all the v23.9 in this file.

Can anyone please suggest me any solution.

Thansk
