cli-sedHow do I use the command line 'sed' command as an example?

The sed command is a powerful command line utility that can be used to perform text manipulation and search operations.

For example, to replace the word "foo" with the word "bar" in a file called example.txt, you can use the following command:

sed -i 's/foo/bar/g' example.txt

This command will replace all occurrences of the word "foo" with "bar" in the file example.txt.

The parts of the command are as follows:

sed - The command to run the sed utility
-i - The flag to indicate that the changes should be made in-place
s/foo/bar/g - The substitution command, which replaces all occurrences of "foo" with "bar"
example.txt - The file to perform the substitution on

For more information about the sed command, you can refer to the GNU sed Manual.
