Using ZSH ZMV to Force Add Leading Zeros

Given a list of episodes that are named with single digits, but you'd like leading zeros:

S1E1.avi
S1E2.avi
S1E3.avi
S1E4.avi

zmv 'S([0-9])E([0-9]).(*)' 'S${(l:2::0:)1}E${(l:2::0:)2}.$3'

They'd now be renamed as follows:

S01E01.avi
S01E02.avi
S01E03.avi
S01E04.avi

Using ZSH ZMV to Rename Split an Episode to Two Episodes

Given a list of episodes that are named to be one, but actually need to span two episodes:

S01E01.avi
S01E02.avi
S01E03.avi
S01E04.avi

zmv 'S([0-9][0-9])E([0-9][0-9]).(*)' 'S$1E${(l:2::0:)$((($2 * 2) - 1))}-E${(l:2::0:)$(($2 * 2))}.$3'

They'd now be renamed as follows:

S01E01-E02.avi
S01E03-E04.avi
S01E05-E06.avi
S01E07-E08.avi

This will also force leading zeros on S and E should they originally be single digits.

Outgoing Email Counts For DirectAdmin Users

Replace $user with the system user and it will return a count of outgoing mails, per-user for the current day ($user and $user.bytes in this directory reset at midnight)

cat /etc/virtual/usage/$user.bytes | grep outgoing | awk -F= '{print $4}' | awk -F\& '{print $1}' | sort | uniq -c | sort -n

Using ZSH ZMV To Mass Rename Files Episodes

This presumes you are in the show folder looking at all the season folders AND the shows have the following format:
### - Episode Title.mkv

zmv 'Season (*)/([0-9])(*) - (*).mkv' 'Season $1/{showtitle} - S0$2E$3 - $4.mkv'

This should leave you with:

Showtitle - S01E01 - Episode Title.mkv

...and so forth.

If you are unsure, add the -n flag to zmv and it will present you the changes versus simply making them.

Note: Replace {$showtitle} with the title of your show. Nested directories with zmv gave me trouble so consider this the one bit of lifting required to save you a bunch of time.
