cli-sedHow can I use the command line to run a sed job?
The command line can be used to run a sed job by using the
sed command. The syntax of the
sed command is
sed [options] script [input-file]. The
script argument specifies the sed commands to be applied to the input file.
For example, the following command will replace the word
dog with the word
cat in the file
input.txt and print the output to the terminal:
sed 's/dog/cat/g' input.txt
The output of the above command will be:
I have a cat.
My cat is white.
sed command has several options that can be used to control its behavior. The
-n option suppresses automatic printing of pattern space, and the
-i option allows in-place editing of files.
script argument is composed of one or more sed commands. The
s command is used to search and replace text, and the
d command is used to delete lines.
