greetings, I have these commands:

base=/u01/Integrity/PMDR/OGL

sed -e '/<ManufacturedProduct>/r /u01/Integrity/PMDR/OGL/Stage/images.xml' ${base}/Stage/SPL.xml > ${base}/Stage/SPLout.xml

where it says: /u01/Integrity/PMDR/OGL/Stage/images.xml
but I want it parameterized like this: ${base}/Stage/images.xml

right now this does not work:
sed -e '/<ManufacturedProduct>/r ${base}/Stage/images.xml' ${base}/Stage/SPL.xml > ${base}/Stage/SPLout.xml

what can I do to get ${base} to be recognized?
thanks.

Use double quotes " instead of the single quotes '

sed -e "/<ManufacturedProduct>/r ${base}/Stage/images.xml" ${base}/Stage/SPL.xml > ${base}/Stage/SPLout.xml

Hi arcee123,

I agree with wmp's comment about quotes.  Double quotes allow for interpolation, which is what you need here.

The '-e' switch is not required here.  Retaining it won't cause a problem, though.
