Limodzi mwa malamulo ofunikira kwambiri omwe mungaphunzire pogwiritsira ntchito mzere wa lamulo la Linux ndi lamulo la pwd lomwe likuyimira ntchito yosindikizira yosindikiza.
Bukhuli lidzakusonyezani momwe mungagwiritsire ntchito lamulo la pwd ndikukuwonetsani njira yeniyeni yomwe mukugwira ntchitoyi ndi ndondomeko yoyenera imene mukugwira.
Mmene Mungapezere Kuti Linux Directory Yomwe Mukulowa
Kuti mudziwe directory yeniyeni yomwe mukutsatira ili:
pwd
Zotsatira za lamulo la pwd zidzakhala ngati chonchi:
/ nyumba / gary
Pamene mukuyendayenda pulogalamu yogwira ntchito idzasintha kuti ikuwonetseni malo omwe muli nawo mkati mwa fayilo.
Mwachitsanzo, ngati mumagwiritsa ntchito lamulo la cd kuti mupite ku foda yamakalata, lamulo la pwd liwonetsa zotsatirazi:
/ nyumba / gary / zikalata
Kodi pwd imaonetsa chiyani pamene mukuyenda kupita kufolda yogwirizana
Pachigawo chino, tidzakhazikitsa zochepa zofotokozera zomwe zikuchitika.
Tangoganizirani kuti muli ndi fayilo yokhazikika motere:
- kunyumba
- gary
- zolemba
- folder1
- folder2
- zolemba
- gary
Tsopano taganizirani kuti munalumikiza fayilo firiji 2 motere:
l--m / nyumba / gary / zolemba / foda1 / nyumba / gary / zolemba / akaunti
Foda ya foda tsopano ikuwoneka ngati iyi:
- kunyumba
- gary
- zolemba
- folder1
- folder2
- nkhani
- zolemba
- gary
Ls command imasonyeza mafayilo ndi mafoda mkati mwa malo ena:
ls -t
Ngati ndathamanga lamulo ili pamwamba pa foda yamapepala anga ndikuwona kuti ku akaunti izo zingasonyeze chonga ichi:
akaunti -> folder2
Zisonyezero zowonjezera zimatanthauzira malo ena mkati mwa fayilo.
Tsopano ganizirani kuti muli mu foda yamakalata ndipo munagwiritsa ntchito lamulo la cd kuti mulowe mu foda yamakalata.
Kodi mukuganiza kuti zotsatira za pwd zidzakhala zotani?
Ngati mukuganiza kuti idzawonetsa / kunyumba / gary / zolemba / akaunti ndiye kuti mudzakhala olondola koma ngati mutayendetsa ls kutsutsana ndi foda yamakalata ndikukuwonetsani mafayilo mu foda yanu folder2.
Yang'anani pa lamulo ili:
pwd -P
Pamene muthamanga lamulo lapamwamba mkati mwa fayilo yowonjezereka mukuwona malo omwe tili nawo ndi / kunyumba / gary / zolemba / foda2.
Kuti muwone foda yoyenera mungagwiritse ntchito lamulo ili:
pwd -L
Izi zikanakhala zanga zikuwonetsanso zofanana ndi pwd zokha zomwe ziri / kunyumba / gary / zolemba / akaunti.
Malinga ndi momwe pwd imakhalira ndi kukhazikitsidwa pa dongosolo lanu pwd lamulo akhoza osasintha kwa thupi kapena angasinthe njira yolondola.
Chifukwa chake ndi chizoloŵezi chabwino kugwiritsa ntchito -P kapena -Likani (malinga ndi khalidwe lomwe mukufuna kuwona).
Kugwiritsa ntchito $ PWD Yowoneka
Mukhoza kuwona zolemba zomwe zikugwiritsidwa ntchito posonyeza mtengo wa $ PWD. Gwiritsani ntchito lamulo ili:
pangani $ PWD
Onetsani Ndondomeko Yoyamba Kugwira Ntchito
Ngati mukufuna kuwona bukhu la ntchito yapitayi mungagwiritse ntchito lamulo ili:
limbani $ OLDPWD
Izi ziwonetseratu zolemba zomwe mudali nazo musanayambe kusuntha.
Zochitika zambiri za pwd
Monga tafotokozera poyamba pwd ikhoza kuchita mosiyana ndi momwe ikukhazikitsira.
Chitsanzo chabwino cha ichi chiri mkati mwa Kubuntu Linux.
Chigoba cha pwd chomwe chimagwiritsidwa ntchito pamene muthamanga pwd chikuwonetsa bukhu logwira ntchito loyenera pamene muli mu fayilo yowonjezereka.
Komabe, ngati mutayendetsa lamulo lotsatilayi muwona kuti likuwonetsa zolemba zogwirira ntchito pamene muli mu fayilo yowonjezereka.
/ usr / bin / pwd
Izi mwachiwonekere sizothandiza kwambiri chifukwa inu mumagwiritsa ntchito lamulo lomwelo koma muli ndi zotsatira zotsatila pamene mukugwiritsidwa ntchito molakwika.
Monga tafotokozera poyamba mukufuna kukhala ndi chizoloŵezi chogwiritsa ntchito -P ndi -L script.
Chidule
Pali kusintha kwina kulikonse kwa lamulo la pwd:
