Dear Friend,

If you want to change the content in the file permanently , you can use "sed" command using the -i option.

If you use -i option it will affect the file also. But if we don't use the -i it will not affect the file content.

The new_file(file name) contain the following content
Hi i am kaushlesh; i am new to Unix.

Code:
 
sed -i 's/;/ ok/g'  new_file

The output
Hi i am kaushlesh ok i am new to Unix
