BLAST is a very powerful and widely used method for querying large sequence databases for sequence proximity with a sequence of interest. This difficult problem requires a fast algorithm designed for nucleic and protein sequences only since their alphabet is limited (5 bases for nucleotides, 21 amino acids for protein), but sequence length can be very long (more than 40000 amino). An example of BLAST installation and usage is provided below.

Crontab entries are great to periodically execute a command, but lack advanced logging facilities. This article will just highlight a rapid tip to enhance this situation.
The cron service is meant to execute periodically a given task, but it lacks a proper logging facility.
