... Both users and system administrators often need to run commands periodically. For example, the system administrator might want to run a command to clean the directories with temporary files ( /tmp љ and /var/tmp љ ) from old files, to keep the disks from filling up, since not all programs clean up after themselves correctly. The cron љ service is set up to do this. Each user has a crontab љ , where he lists the commands he wants to execute and the times they should be executed. ...

Prague, August 16, 2006 . Another problem that was making it difficult to automatically merge GCVS and survey catalogs has been recently solved: 'old' variable stars also had only very rough coordinates. The GCVS has been identified, on a star-by-star basis, with positional catalogs. ... The total number of stars we were unable to identify, at least tentatively, is only 200, most of them from two or three sources of especially unreliable positional information. ...
