Ntawm kev tso cai rau cov sijhawm ua kom haum, ncua ntawm POSIX.2 tus qauv. Nws lees txais lub sij hawm ntawm daim ntawv HH: MM khiav hauj lwm rau ib lub sijhawm twg.

/usr/share/doc/at-3.1.8/timespec muaj lub ntsiab txhais ntawm lub caij nyoog specification.
Rau ob qho tib si ntawm thiab batch , commands tau nyeem los ntawm cov qauv tawm tswv yim los yog cov ntaub ntawv teev xeeb nrog -f xaiv thiab tseg. Cov chaw ua hauj lwm, lub cheeb tsam (tshwj tsis yog rau lub sijhawm TERM , ZEEJ thiab _ ) thiab lub umask khaws cia los ntawm lub sij hawm thov. Ib lub npe ntawm - los yog pawg batch - hais kom ua los ntawm dej (1) lub plhaub yuav khaws cov neeg siv daim npav tam sim no. Tus neeg siv yuav raug xa tawm yuam kev thiab txheem tso tawm los ntawm nws cov lus txib, yog tias muaj. Kev xa ntawv yuav raug xa mus siv cov lus txib / usr / sbin / sendmail . Yog thaum tua tom qab ntawm lub plhaub (1) lub plhaub, tus tswv ntawm tus ID nkag mus plhaub yuav tau txais cov ntawv xa tuaj.
Tus superuser yuav siv cov lus txib no txhua zaus. Rau lwm cov neeg siv, kev tso cai siv los ntawm kev txiav txim siab los ntawm cov ntaub ntawv /etc/at.allow thiab /etc/at.deny .
Yog tias cov ntaub ntawv /etc/at.allow tshwm sim, tsuas yog usernames hais hauv nws tau tso cai rau siv.
Yog tias /etc/at.allow tsis muaj nyob, /etc/at.deny xyuas, txhua lub username tsis hais hauv nws ces pub tau siv ntawm .
Yog hais tias tsis muaj ib qho, tsuas yog tus superuser tau siv kev siv ntawm.
Tus empty /etc/at.deny txhais tau hais tias txhua tus neeg siv tau siv cov lus txib, qhov no yog qhov kev tsim teeb meem.

siv queue teev. Ib qho kev xaiv ntawm cov queue muaj ib tsab ntawv; siv tau queue kev xaiv los ntawm ib tus z rau . thiab A rau Z. Lub queue yog lub neej ntawd rau ntawm thiab b bue rau batch . Queues nrog cov tsiaj ntawv loj dua nrog nce niceness. Qhov tshwj xeeb queue "=" yog tseg rau cov hauj lwm uas tam sim no khiav. Yog tias txoj haujlwm raug xa mus rau ib qho queue uas muaj ib daim ntawv loj tshaj, nws raug kho li yog nws tau xa mus rau batch rau lub sijhawm ntawd.
