Question

The title says all. i need to replace a property value whom i don’t know to a different value.
i’m trying this:

#!/bin/bash
sed -i "s/myprop=[^ ]*/myprop=$newvalue/g" file.properties

i get sed: -e expression #1, char 19: unknown option tos’`

I think the problem is that $newvalue is a string that represents a directory so it messes up sed.

What can I do ?

Answer 1

sed can use characters other than / as the delimiter, even though / is the most common. When dealing with things like pathnames, it’s often helpful to use something like pipe (|) instead.
