[Remove line with "sed"] Using sed to remove a line in a file #cli #sed

GNU sed

sed -i "37d" /path/to/file

sed in macOS runs a bit differently than GNU as you have to define a backup file extension before editing the original file:

sed -i.bak "37d" /path/to/file

Both of the above will remove line 37 from the specified file.

d is the command to delete a pattern space, while 37 stands for the 37th line.

In macOS it will create a backup of the original file first based on the extension given after the -i flag, in this case being .bak. A /path/to/file.bak will be created and the original file will be updated with the removed line 37.
