As another lister stated "sed" is another option. "man sed"
With "sed", "tr", "awk", "grep", and "exec" you should be able to do just about any search/replace operation.

Thanks for the advice. What I'm trying to accomplish is a
search/replace function for strings, not individual characters. From
reading "man tr" I get the sense that tr operates strictly on
characters. I'm sure the bit about the /tmp directory will be useful
in future projects.

In the shell this would be "/usr/bin/tr '\r' '\n' < /filepath |

The extra "\" remove Applescript's interference.

The other helpful thing this demonstrates is the use of the /tmp

Could someone point me in the right direction as to how to do a find
