Pali malamulo awiri othandiza kwambiri mu Linux zomwe zimakuwonetsani gawo la fayilo. Choyamba chimatchedwa mutu ndipo chosasintha, chimakuwonetsani mizere 10 yoyamba mu fayilo. Lachiwiri ndi lamulo la mchira limene mwasala limakulolani kuti muwone mizere khumi yomaliza mu fayilo.
N'chifukwa chiyani mukufuna kugwiritsa ntchito limodzi mwa malamulo awa? Bwanji osangogwiritsa ntchito kampeni kuti muwone fayilo lonse kapena mugwiritse ntchito mkonzi monga nano ?
Tangoganizani fayilo yomwe mukuwerengayo ili ndi mizere 300,000.
Taganiziraninso kuti fayilo imadya malo ambiri a diski.
Kugwiritsidwa ntchito kwapadera kwa lamulo la mutu ndikoonetsetsa kuti fayilo yomwe mukufuna kuyang'ana ndidi fayilo yoyenera. Mutha kuwuza ngati mukuyang'ana pa fayilo yoyenera poona mizere yochepa. Mutha kusankha kugwiritsa ntchito mkonzi monga nano kuti musinthe fayilo.
Lamulo la mchira ndi lothandiza powona mizere yochepa ya mafayilo ndipo ndi bwino kwambiri kuti muwone zomwe zikuchitika mu fayilo yamakalata yomwe ili mu fayilo / var / log .
Bukhuli lidzakusonyezani momwe mungagwiritsire ntchito lamulo la mchira kuphatikizapo kusintha kwina kulikonse.
Chitsanzo Chogwiritsa Ntchito Mchira
Monga tafotokozera poyamba mchira umapereka mwachindunji umasonyeza mizere 10 yomaliza ya fayilo.
Chidule cha lamulo la mchira ndicho:

Momwe Mungatchulire Nambala Ya Mzere Kuwonetsera
Mwinamwake mukufuna kuwona kuposa mizere 10 yomaliza ya fayilo. Mutha kufotokoza nambala ya mizere yomwe mukufuna kuiwona pogwiritsa ntchito lamulo ili:
sudo mchira -n20
Chitsanzo cha pamwambachi chikhoza kusonyeza mizere 20 yomaliza ya fayilo.
Njira ina mungagwiritsire ntchito -nikani kuti muyambe kufotokoza chiyambi cha fayilo. Mwinamwake mukudziwa mzera woyamba 30 mu fayilo ndi ndemanga ndipo mukufuna kungowona deta mkati mwa fayilo. Pankhaniyi, mungagwiritse ntchito lamulo ili:
sudo mchira -n + 20
Lamulo la mchira limagwiritsidwa ntchito limodzi ndi lamulo loonjezera kuti muwerenge fayilo tsamba panthawi.
Mwachitsanzo:
sudo mchira -n + 20
| Zambiri
Lamulo ili pamwambalo limatumiza mizere 20 yotsiriza kuchokera ku filename ndi mapaipi monga chongowonjezera ku lamulo loposa:
Mukhozanso kugwiritsa ntchito mchira lamulo kuti muwonetse nambala yina ya maofesi m'malo mzere:
sudo mchira -c20
Apanso mungagwiritse ntchito kusinthana komweku kuti muyambe kusonyeza kuchokera ku nambala ina yachinyumba motere:
sudo mchira -c + 20
Mmene Mungayang'anire Chizindikiro Chajambula
Pali malemba ambiri ndi mapulogalamu omwe sagwiritsidwa ntchito pawindo koma amathandizira pa fayilo yazamu pamene akuthamanga.
Pachifukwa ichi, mungafune kufufuza fayilo lolemba pamene likusintha.
Mukhoza kugwiritsa ntchito mchira wakutsatira womwewo kuti muwone momwe chipikacho chimasinthira masekondi ambiri.
sudo mchira -F -s20
Mukhozanso kugwiritsa ntchito mchira kuti mupitirize kufufuza chipika mpaka ndondomeko ifa motere:
sudo mchira -F --pid = 1234
Kuti mupeze id yotchulidwa muzokambirana mungagwiritse ntchito lamulo ili:
ps -ef | grep
Mwachitsanzo, taganizirani kuti mukukonza fayilo pogwiritsa ntchito nano. Mukhoza kupeza chidziwitso cha nano pogwiritsa ntchito lamulo ili:
ps -ef | grep nano
Zotsatira kuchokera ku lamulo zidzakupatsani chidziwitso cha ndondomeko. Tangoganizirani njira yolembayi ndi 1234.
Mukutha tsopano kuthamanga mchira motsutsana ndi fayilo yosinthidwa ndi nano pogwiritsa ntchito lamulo ili:
sudo mchira -F --pid = 1234
Nthawi iliyonse fayiloyo imasungidwa mkati mwa nano mzere wa mchira udzatenga mizere yatsopano pansi. Lamulo limangoima pamene mkonzi wa nano watsekedwa.
Mmene Mungathenso Kutsogolera Mchira
Ngati mulandira cholakwika pamene mukuyesa kuyendetsa mchira chifukwa sichikupezeka chifukwa china ndiye mutha kugwiritsa ntchitoyeso yamayendedwe kuti muyese kuyesa mpaka fayilo ikupezeka.
mchira wothandizira - kutulukira -F
Izi zimagwira ntchito pamodzi ndi -F kusintha kumene mukuyenera kutsatira fayilo kuti muyesenso kuyesa.
Chidule
Bukuli likuwonetsa ntchito zomwe zimagwiritsidwa ntchito ndi mchira.
Kuti mudziwe zambiri za mchira ndikulamula kuti mugwiritse ntchito lamulo ili:
munthu mchira
Mudzazindikira kuti ndaphatikizapo sudo mkati mwa malamulo ambiri. Izi ndizofunikira pamene mulibe zilolezo monga wosuta wanu kuti muwone fayilo ndipo mukufuna zilolezo zapamwamba.
