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-places/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.
