(old)Puppy Linux Discussion Forum

This is sending me silly...

Using puppy v1.0.1 or v1.0.4...

# tmpdir=/tmp/root
# echo /root/etc/hosts | sed 's/root/abc/'

...gives /abc/etc/hosts

# echo /root/etc/hosts | sed 's/root/$tmpdir/'

...gives /$tmpdir/etc/hosts

# echo /root/etc/hosts | sed "s/root/$tmpdir/"

...gives "sed: -e expression #1, char 9: Unknown option to 's'"

The sed FAQs suggest the variable substitution happens when the double-quotes are used... but all I get is the syntax error.

Gnu sed v4.0.7 is included in both Puppy v1.0.1 and v1.0.4.

What do I have to do to get the variable substitution to work!?

tmpdir=/tmp/root
echo /root/etc/hosts | sed "s%/root%$tmpdir%"

Great. Many thanks. Forgot all about the other delimiters

got beaten to the punch

Bladehunter: isn't it worth answering all those easy questions to find one like this one?
