cli-sedHow do I use the sed command in the command line interface?
sed command is a powerful tool in the command line interface (CLI) that can be used to search, find, and replace strings in text files. It is a stream editor, meaning that it reads input from files or from the standard input, and writes output to the standard output.
For example, to replace the word
dog with the word
cat in the file
animals.txt, the command would be:
sed 's/dog/cat/' animals.txt
The output of the command would be the file
animals.txt with all instances of the word
dog replaced with the word
The command is composed of several parts:
sed: The command to invoke the stream editor
s/dog/cat/: The search and replace pattern, where
sindicates search and replace,
dogis the string to search for, and
catis the string to replace with
animals.txt: The file to be edited
