The clauses of a find are carried out in order, left to right. If a clause succeeds, processing continues; if it fails, this candidate is abandoned and the next file tested.

• In the case above, -type f tests whether the current candidate is a file, or directory or link or something else. Processing continues only if it is a file.
• Next, the name of the file is printed. Printing always considered to succeed.
• Finally, the name is tested to see if matches the glb pattern, '*.pl'. Whether it matches or not, processing is finished for this candidate.

Presumably, what you really want is to defer printing until after you have selected only '*.pl' files:

.... `find '.' -type f -name '*.pl' -print` ....

info find or man find is your friend. In particular, watch for the case where you want to match one of two patterns, using -o. You have to group the patterns using parentheses, escaped to prevent the shell from interpreting them:

find . \( -name '.pl' -o -name '*.pod' \) -print
