2.4. Using cron to automate indexation
The most common way to set up indexation is to have a cron task execute it
every night. For example the following crontab entry would do it every day
at 3:30AM (supposing recollindex is in your PATH):
30 3 * * * recollindex > /tmp/recolltrace 2>&1
The usual command to edit your crontab is crontab -e (which will usually
start the vi editor to edit the file). You may have more sophisticated
tools available on your system.
