Example Text File​

Let's create a file named example.txt with the word "Worshington" in it several times.

Worshington is a beautiful city.
Many people visit Worshington every year.
The history of Worshington is fascinating.

Using sed to Replace "Worshington" with "Washington"​

Replace in Place​

To replace "Worshington" with "Washington" in the existing file and save the changes in the same file, use the following command:

 sed -i 's/Worshington/Washington/g' example.txt

Create a New File​

To replace "Worshington" with "Washington" and save the changes in a new file while keeping the original file unchanged, use the following command:

 sed 's/Worshington/Washington/g' example.txt > new_example.txt

The -i means insert in place. The s means search for. The g means do it globally ( everywhere in the file )
If you leave the g option out, if will just replace the first word, not all of the words.

These commands will help you replace the word "Worshington" with "Washington" globally in the text file.
