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.

Hey there did you try tr and specify only alpha characters?

tr  '[:upper:]' '[:lower:]'

Hope that helps :)

output:

$ tr "/v23.9" "/ABCDE" < test.txt
ABC
-p /home/user/a/b/ABCDE/library -l /home/user/a/b/ABC/ABCDE testDexe
DEF
-r ABCDE /c/d/f -p /home/user/a/b/ABCDE/library -l /home/user/a/b/ABC/ABCDE testDexe

i dont want these RED color items to change but want only green colur items.

Assuming you mean the v23.9 directly after the -p argument

sed -e 's;/v23.9/;/abcde/;g' file1.txt > file2.txt

If you mean after the -p and after -l arguments then

sed -e 's;/v23.9;/abcde;g' file1.txt > file2.txt
