cli-sedHow do I use the sed command line in bash?
sed command line is a powerful tool for text manipulation in bash. It allows users to search, find, and replace text in files. To use
sed, the syntax is
sed [options] 'command' file(s).
For example, to replace all occurrences of the word "dog" with "cat" in the file
animals.txt, the following command can be used:
sed 's/dog/cat/g' animals.txt
This command will output the contents of
animals.txt with all occurrences of "dog" replaced with "cat".
The command consists of the following parts:
sed: the command itself
s/dog/cat/g: the search and replace command, where
sstands for substitute,
dogis the search pattern,
catis the replacement string, and
gstands for global, meaning to replace all occurrences
animals.txt: the file to be modified
For more information on
sed and its options, see the GNU sed Manual.
