Qalisa umyalo we-Linux njalo njalo nge-Watch

Ukwenza imisebenzi ethile kungasiza kakhulu, ikakhulukazi uma kuyimisebenzi ebandakanya ukusebenza kusuka kukhonsoli. KuLinux distro yethu singaba namathuluzi ahlukahlukene wokuzenzela imisebenzi, ngaphezu kokukwazi ukubhala imibhalo ye-Bash ukwenza uchungechunge lwemiyalo noma isenzo ngaphandle kokuhamba ngakunye, futhi sibangeze ekuqaleni kohlelo noma ukuhlelela ukuthi kuqhubeke usuku oluthile.noma umzuzwana ngaphandle kokuthi senze noma yini futhi ngendlela esobala.

Kulesi sihloko sizobona ukuthi ungakwenza kanjani sebenzisa umyalo njalo lapho usebenzisa iwashi. Ukubuka kungumyalo ongenza uhlelo noma omunye umyalo njalo ngemizuzwana engu-X esiyibeka kuyo. Ngakho-ke sihlela ukwenziwa okuphindaphindwayo komsebenzi othile. Kungasebenza ikakhulukazi ekubonisaneni ngezikhathi ezithile noma kweminye imisebenzi yesondlo njll. Ungasifaka kunoma yini njengoba ubona lapha, umkhawulo umcabango wakho ...

Uma ufuna i-loop noma uphinda ukuphela, ungasebenzisa i-CTRL + C ukuqeda isenzo sokubuka noma vele uvale iwindi lokugcina lapho lisebenza khona. I-syntax yokubuka ilula kakhulu futhi inayo le physiognomy:

Isibonelo, ake sibone isibonelo esisebenzayo Ihlola isikhala esisetshenziswe kumahlukaniso ethu njalo ngemizuzu emi-5 (amasekhondi angama-300). Ngokuya endaweni esetshenzisiwe neyamahhala yokwahlukaniswa kwethu, thayipha "df -h", ngoba ngewashi kungaba:

watch -n 300 df -h

Ungahlola indoda yokubuka ukuze ubone zonke izinketho inakho, ngoba iguquguquka impela. Ngaphezu kwalokho, singaqondisa kabusha umbuzo kufayela ukuze umphumela uprintwe ku-.txt ngokwesibonelo:

 watch -n 300 df -h > espacio_usado.txt 

Ngale ndlela, singakwazi hlola ifayela used_space.txt lapho sizobona khona ukuthi into efanayo ikhonsoli ebizosikhombisa yona uma uthayipha i-df -h iphrintiwe. Cabanga inani lemisebenzi ongayenza ...
