Replace exact word by perl
my inputfile:

This is a test and only a test for production - prod.

Code:
echo "This is a test and only a test for production - prod" | perl -pi -e 's/prod/test/g'

outputfile:
Code:
This is a test and only a test for testuction - test

I only want to replace prod, not production.

I also tried to use sed:

Code:
echo "This is a test and only a test for production - prod" | sed -e 's/prod/test/g'
This is a test and only a test for testuction - test

Thank you in advance for helping.

This highly depends on e.g. the sed version you are running. With mine(sed (GNU sed) 4.2.2), this works:
Code:
echo "This is a test and only a test for production - prod" | sed -e 's/\<prod\>/test/g'
This is a test and only a test for production - test

I found this on unix.com
Code:
sed 's/\<apple\>/XXX/g' filename

and solved my sed

I am digging for perl. Again, thank you.

You can try:
Code:
perl -pi -e 's/\bprod\b/test/g'
