sed (variable)
HOw can I use any variable in sed command.

For example I am using 'sed -e 's/?/$ORACLE_HOME/g' $file_name

Here it replaces ? with $ORACLE_HOME. Instead of it I need actual value of $ORACLE_HOME. How can I do that?

Please advice.

Thanks in advance.

ORACLE_HOME u had provided contains "/"
when substituting with sed
they have to be disabled with a "\"

following is just an example

echo "abc" | sed -e 's/abc/\/diqr001\/opt\/tools\/oracle\/product\/9.2.0/'

change ur script accordingly

Wouldn't double-quoting solve the sed expression work ?

Code:
sed -e "s/abc/$ORACLE_HOME/g" <filename>
