The batch command operates similarly to the at command, but with three significant differences:
- You can only use the batch command interactively.
- Rather than scheduling jobs to execute at a specific time, you add them to the queue, and the batch command executes them when the system’s average load is lower than 1.5.
Uyicwangcisa njani imisebenzi usebenzisa umyalelo we-AT?
Kwi-imeyile yomyalelo, chwetheza i-net start command, uze ucinezele u-ENTER ukubonisa uluhlu lweenkonzo ezisebenzayo ngoku. Kuncedo lomyalelo, yenza elinye lala manyathelo alandelayo: Ukujonga uluhlu lwemisebenzi oyicwangcisiweyo ngokusebenzisa kumyalelo, chwetheza kwi \umgca wegama lekhompyutha, kwaye ucinezela ENTER.
Yintoni inkqubo yokucwangcisa kwi-Unix?
I-LWP yinto ecwangciswe ngumcwangcisi wenkqubo ye-UNIX, leyo imisela ukuba iinkqubo ziqhutywa nini. Umcwangcisi ugcina iinkqubo eziphambili ezisekelwe kwiiparamitha zoqwalaselo, inkqubo yokuziphatha, kunye nezicelo zabasebenzisi. Umcwangcisi usebenzisa ezi zinto ziphambili ngokubaluleka ukumisela ukuba yeyiphi inkqubo elandelayo.
What is batch process in Linux?
