Ah, yeah, that's why I have a script, mythlink.sh, that includes the 
desired mythlink.pl command line(s).  Then, the cron job (or whatever) 
can simply run it as "mythlink.sh".  I actually have my script create 5 
different views (sorted by start time, title, recording group, category, 
and original airdate--so I can find files using whatever view is easiest).

I'm attaching a copy of my script for reference.

Yeah, or it can be run as a user job or--even better--as a MythTV System 
Event.

#!/bin/bash
#
# mythlink.sh
#
# Creates readable symlinks referring to MythTV recordings using the
# mythlink.pl script
#
# Usage:
#    mythlink.sh [chanid starttime]
#
#        chanid
#            The channel ID of the recording for which a link should be made
#
#        starttime
#            The starttime of the recording for which a link should be made
#
#    If chanid and starttime are not provided, links will be created for all
#    recordings.  This should be done periodically to remove links to
#    recordings that have been deleted.
#

### Modify these values for your installation ###

# The path in which the views ("pretty" links) will be created
VIEWS_PATH=/srv/mythtv/tv/views

# The location of the mythlink.pl script
# The default value assumes mythlink.pl is in the user's PATH
COMMAND=mythlink.pl

# The group used to create the links
# This allows multiple users to run the script, assuming all are in the
# specified group
GROUP=mythtv


### The following directory names and formats may be customized ###

# Formats may be constructed using the format specifiers listed in the
# output of "mythlink.pl --help"

# Files will be sorted "alphabetically" so the appropriate fields on which you
# would like to sort should be placed at the beginning of the format

# To add a custom format, simply include a directory name and format in the
# environment variables below using the syntax shown below.

# The names of the directories containing the views
DIRECTORIES=(
