Full Version: Inverse Of Echo?
Linuxhelp > Support > Technical Support
hey, does anybody know a command that can remove lines from a file kind of like how echo works but in reverse? Just trying to write a sript and I am comming up short. Thanks.
sed can selectively delete lines from a file. Something like

sed -e "/matching text/d" filename
Half way there, but that didn't seem to do exactly what I want. It did manage to delete the line, but not from the actual file.

I am trying to figure out a way to use it though using someting like xargs, but hummm.

Any ideas?
Could you clear the file, and then re-echo the modified text?
