I added some Cisco MDS devices running NX-OS and noticed when it runs "show environment fan" it dumps the current fan (or fans) speed, causing a diff on every run.

After some testing I've added the below to sub ShowEnv, and although it isn't as neat as the process in ShowEnvTemp it seems to work.

        if (/(fan speed)/i) {
            ProcessHistory("COMMENTS","","","!Env: $_");
            while (<$INPUT>) {
                tr/\015//d;
                goto EndShowEnv if (/^$prompt/);
                if (/(^ChassisFan)(.*)(\d\d\d\d\s\s[-]\s\s\d\d\d\d)/) {
                   $_ = sprintf("%s%-". length($2)."s%s\n", $1, $2, "");
                }
                ProcessHistory("COMMENTS","","","!Env: $_");
                last if (/^\s*$/);
            }
            next;
        }

Perhaps someone who is more skilled than me could take this and do it more cleanly? ShowEnvTemp removes the unused column text (CurTemp), although I'm not sure how.
