cli-sedHow do I use the command line sed utility?
The sed
utility is a powerful command line tool for editing text. It can be used to perform a variety of tasks, such as replacing text, removing lines, and transforming text.
For example, to replace all occurrences of the word "foo" with the word "bar", you can use the following command:
sed 's/foo/bar/g' filename
This will replace all occurrences of "foo" with "bar" in the file filename
.
You can also use sed
to remove lines from a file that contain a certain string. For example, to remove all lines containing the word "foo", you can use the following command:
sed '/foo/d' filename
This will remove all lines containing the word "foo" from the file filename
.
You can also use sed
to transform text. For example, to convert all occurrences of the word "foo" to uppercase, you can use the following command:
sed 's/foo/\U&/g' filename
This will convert all occurrences of the word "foo" to uppercase in the file filename
.
