Sithini isiphumo somyalelo kabani?
Ingcaciso: ngubani umyalelo ophumayo iinkcukacha zabasebenzisi abathe bangena ngoku kwisistim. Imveliso ibandakanya igama lomsebenzisi, igama letheminali (apho bangene kuyo), umhla kunye nexesha lokungena kwabo njl.njl.
Ndiyibonisa njani i-AM okanye i-PM ngonobumba omncinci kwi-Unix?
Iinketho eziNxulumene nokuFomatha
- %p: Shicilela i-AM okanye isalathisi se-PM ngoonobumba abakhulu.
- %P: Shicilela isibonisi se-am okanye se-pm ngoonobumba abancinane. Qaphela i-quirk ngezi ndlela zimbini. Unobumba abancinane u-p unika imveliso yonobumba abakhulu, unobumba abakhulu P unika imveliso enobumba abancinane.

- %b – Ibonisa igama lenyanga elishunqulelweyo lendawo.
- I-%B – Ibonisa igama lenyanga elipheleleyo lendawo.
- %c – Ibonisa umhla ofanelekileyo wendawo kunye nexesha elifanelekileyo (ehlala ikho).

Umhla we-Linux Iinketho zeFomathi yoMyalelo
Aba ngabasebenzi abaqhelekileyo bokufomatha kumyalelo womhla: I-%D – Umhla wokuboniswa njenge mm/dd/yy. %Y – Unyaka (umz., 2020)
