lub xeem, qhov kawg - qhia seb lub sijhawm dhau los ntawm cov neeg siv
SYNOPSIS
kawg [ -R ] [ - num ] [- n num ] [ -adiox ] [- t ntawv ] [- t YYYYMMDDHHMMSS ] [ npe ... ] [ tty ... ]
[- t ] [- t YYYYMMDDHHMMSS ] [ -adiox ] [ npe ... ] [ tty ... ]
KEV POM ZOO
Xaus searches rov qab los ntawm cov ntaub ntawv / var / log / wtmp (los yog cov ntaub ntawv teev los ntawm tus chij fais -F ) thiab qhia cov npe ntawm tag nrho cov neeg nkag tau hauv (thiab tawm) txij li cov ntaub ntawv ntawd tau tsim. Lub npe ntawm cov neeg siv thiab cov laub coj tuaj yeem muab tau rau, qhov twg qhov kawg yuav qhia tau tias cov ntawv nkag rau cov lus sib cav xwb. Cov npe ntawm ttys yuav muab abbreviated, yog li lub xeem 0 yog tib yam li lub xeem tty0 .
Thaum kawg ntes ib qho SIGINT teeb liab (generated los ntawm kev sib txuam, feem ntau tswj tau-C) los yog SIGQUITsignal (generated los ntawm tus yuam sij tawm, feem ntau tswj- \), kawg yuav qhia tias deb npaum li cas nws tau tshawb fawb los ntawm cov ntaub ntawv; nyob rau hauv cov ntaub ntawv ntawm SIGINT lub teeb liab kawg ces mam li txiav.
Tus neeg siv pseudo reboot cav txhua lub sijhawm rebooted. Yog li qhov kawg reboot yuav qhia tau cov npe ntawm txhua qhov reboots vim cov ntaub ntawv ua tau tsim.
Lastb yog tib yam li lub xeem , tshwj tsis yog los ntawm lub neej ntawd nws qhia tau hais tias cov ntawv teev npe ntawm cov ntaub ntawv / var / log / btmp , uas muaj tag nrho cov tus ID nkag mus tsis zoo.
XAIV
- num
Qhov no yog ib qho suav qhia txog tias muaj pes tsawg kab qhia.
-num num
Tib yam.
-t YYYYMMDDHHMMSS
Muab lub xeev cov logins tso rau hauv lub sijhawm teev tseg. Qhov no yog qhov tseem ceeb, piv txwv li, los txiav txim tau yooj yim uas tau nkag mus rau hauv ib lub sij hawm twg - qhia tias lub sij hawm nrog -t thiab nrhiav "tseem nkag tau rau hauv".
-R
Suppresses cov zaub ntawm lub npe hostname.
-a
Qhia cov hostname hauv kab kawg. Pab nrog nrog tus chij tom ntej.
-d
Rau cov tsis yog lub zos cov logins, Linux cov khw muag khoom tsis yog tus tswj tuav lub npe xwb ntawm cov chaw taws teeb sab nraud, tiam sis nws tus lej IP thiab. Qhov kev xaiv no txhais IP tus xov tooj rov qab rau hauv ib lub hostname.
-i
Qhov kev xaiv no zoo li -d nyob rau hauv uas nws qhia txog tus IP naj npawb ntawm cov chaw taws teeb sab nraud, tab sis nws qhia txog tus IP naj npawb ntawm cov lej thiab cov cim dots.
-am
Nyeem cov ntaub ntawv qub (wtmp) cov ntaub ntawv (sau los ntawm kev siv linux-libc5).
-x
Taw lub kaw qhov system kaw thiab khiav cov kev hloov theem.
SAIB ALSO
shutdown (8), login (1), init (8)
Tseem ceeb: Siv tus txiv neej hais kom ua ( % tus txiv neej ) seb qhov kev hais kom raug siv hauv koj lub computer.
