cli-sedHow do I use the sed command in the command line interface?
The 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 cat
.
The command is composed of several parts:
sed
: The command to invoke the stream editors/dog/cat/
: The search and replace pattern, wheres
indicates search and replace,dog
is the string to search for, andcat
is the string to replace withanimals.txt
: The file to be edited
