Confused with sed...

Yes I know this is a bad use of cat, but just ignore it please :P
My problem is with sed.

File: "newFile" contains:
day

Command I run:
cat newFile | sed 's/day/night'

This returns:
sed: -e expression #1, char 11: unterminated `s' command

Why???

Hi maximus73,

Because substitute command has three slashes, to separate the regex part, the replacement string and flags.

It should be:
Code:
$ cat newFile | sed 's/day/night/'
