How do I use CLI sed to replace text? // plain
The sed
command line utility can be used to replace text. It is a powerful tool that can be used to manipulate text in a variety of ways.
To use sed
to replace text, you need to provide a search pattern and a replacement string. The following example shows how to replace the word 'foo' with 'bar':
sed 's/foo/bar/g' input.txt
This command will replace all occurrences of 'foo' with 'bar' in the file input.txt
.
The structure of the command is as follows:
s
: stands for 'substitute'/foo/
: the search pattern/bar/
: the replacement stringg
: stands for 'global', meaning that all occurrences of the search pattern should be replaced
You can also use sed
to replace text in multiple files. To do this, you can use the -i
flag, which stands for 'in-place':
sed -i 's/foo/bar/g' *.txt
This command will replace all occurrences of 'foo' with 'bar' in all .txt
files in the current directory.
