sed Delete command Delete one line containing a pattern
Example
Given a file file.txt with the following content:
line 1
line 2
line 3
You can delete a line from file content with the d command.
The pattern to match is surrounded with default / delimiter and the d command follows the pattern:
sed '/line 2/d' file.txt
The above command will output:

line 3
To edit the file in place, use the -i option:
sed -i '/line 2/d' file.txt
