sed question

virendratp · 09-10-2004, 12:26 AM

Hi all,
I am facing a problem with sed. I want to replace a constant string with an environment variable $BASEDIR.
I tried
sed -e "s/this/$BASEDIR/g" temp.txt
sed -e 's/this/'"$BASEDIR"'/g' temp.txt

but it gives me an error
sed: -e expression #1, char 13: Unknown option to `s
for both the cases.

Any help would be appreciated.

Thanks.

The problem is due to the variable containing a forward slash, which is what you are using a a separator in the sed command. Try this instead:
sed -e 's#this#'"$BASEDIR"'#g' temp.txt
