When I have to do this sort of thing I usually use sed to spit out a `shell
script', which I can check for correctness, and then feed to `sh -v' for
execution.

E.g.,:

   tla inventory -s | sed -n "s/\(.*\)\.tmpl\$/tla mv '&' '\1.html'/p"

For checking and,

   tla inventory -s | sed -n "s/\(.*\)\.tmpl\$/tla mv '&' '\1.html'/p" | sh -v

for execution.

The sed `-n' option, and the "p" appended to the s/// command cause sed to
delete any input lines that don't get substituted; one could also just omit
them, and use an additional "grep ..." before the sed.

Note the use of '...' quoting around the filenames in the output to guard
against shell quoting problems with odd filenames (and thus the use of "..."
quoting to quote the sed commands and the subsequent escaping of sed $
meta-character).
