Me pehea te kimi i to raupapa me te Pwd Command

Ko tetahi o nga whakahau tino nui ka ako koe ina whakamahia te raina whakahau Linux ko te ture pwd e tu ana ki te tuhi i te whaiaronga mahi.

Ka whakaatu tenei aratohu ki a koe ki te whakamahi i te whakahau pwd, ka whakaatu ki a koe te huarahi ara ki te whaiaronga e mahi ana koe me te whaiaronga arorau kei te mahi koe.

Me pehea te kimi i tehea rarangi Linux kei a koe kei roto nei

Hei kite i tehea whaiaronga e whakahaerehia ana e koe i tenei wa:

pwd

Ko te putanga mo te whakahau pwd he mea penei:

/ home / gary

Ka huri koe i te punaha ka huri te whaiaronga mahi ki te whakaatu i to tuunga o teianei i roto i te punaha kōnae.

Hei tauira, ki te whakamahi koe i te tono cd hei whakatere ki nga tuhinga tuhinga ka whakaatu te ture pwd i nga mea e whai ake nei:

/ home / gary / tuhinga

He aha te Pwd Whakaatu Ina Ka Whakauruhia koe ki tetahi Kōpaki Hono Hononga

Mo tenei waahanga, ka tuhia he waahanga iti hei whakamarama i te ahuatanga.

Whakaarohia he hanganga kōpaki e whai ake nei:

• home
  • Tuhinga
    • tuhinga
      • kōpaki1
      • kōpaki2

Na, whakaarohia e koe he hononga tohu ki te kōpaki 2 e whai ake nei:

ln -s / home / gary / documents / folder1 / home / gary / documents / accounts

Ka penei te penei:

• home
  • Tuhinga
    • tuhinga
      • kōpaki1
      • kōpaki2
      • nama

Kei te whakaatu te ture i nga kōnae me nga kōpaki i roto i tetahi tauwāhi motuhake:

ls -lt

Ki te rere ahau i te whakahau i runga ake nei mo taku kōpaki tuhinga ka kitea e au mo nga kaute ka whakaatuhia he penei:

pūkete -> kōpaki2

Ko nga hono tohu e tohu ana ki tetahi atu wahi i roto i te punaha kōnae.

Na whakaarohia kei roto koe i te kōpaki tuhinga, a whakamahia ana e koe te tono cd kia neke ki te kōpaki pūkete.

He aha to whakaaro ko te putanga o te pwd?

Mena ka whakaarohia e koe ka whakaatuhia e koe / whare / kaari / tuhinga / putea ka tika koe engari ki te rere koe i te whakahau a te komiti mo te putea kaute kei te whakaatu ki a koe nga kōnae i roto i te kōpaki folder2.

Tirohia te whakahau e whai ake nei:

pwd -P

Ina rere koe i te whakahau i runga ake i roto i te kohinga hononga honorangi ka kite koe i te tauranga taiao i roto i to maatau ko / home / gary / documents / folder2.

Hei kite i te kōpaki arorau ka taea e koe te whakamahi i te whakahau e whai ake nei:

pwd -L

Ma tenei e whakaatu mai i te ahua o te pwd i runga i a ia ano he / home / gary / documents / accounts.

I runga ano i te tikanga o te pwd ka kohia, ka whakaturia ki runga ki to rorohiko, kaore pea te ture pwd e taunoa ki te ara tinana, kaore pea i te huarahi taapiri.

Na reira ko te tikanga pai ki te whakamahi i te -P-a -L te whakawhiti (i runga i nga whanonga e hiahia ana koe ki te kite).

Te whakamahi i te $ PWD Variable

Ka taea e koe te tiro i te mahinga mahi o naianei ma te whakaatu i te uara o te tau $ PWD. Whakamahia noa te whakahau e whai ake nei:

echo $ PWD

Whakaatuhia te Whaiaronga Mahi Mua

Ki te hiahia koe ki te tiro i te whaiaronga mahi o mua ka taea e koe te whakahaere i te whakahau e whai ake nei:

echo $ OLDPWD

Ka whakaatu tenei i te whaiaronga i mua i to nekehanga ki te whaiaronga o naianei.

Tuhinga o mua

Ka rite ki te korero i mua atu i te pwd he rereke te rereketanga i runga i te pehea o te tautuhinga.

He tauira pai tenei kei roto i te Kubuntu Linux.

Ko te putanga anga o te pwd e whakamahia ana i te wa e whakahaere ana koe i te pwd e whakaatu ana i te whakamahinga mahi arorau ina kei roto koe i te kōpaki honohono.

Engari, ki te whakahaere koe i te whakahau e whai ake nei ka kite koe ka whakaatuhia te whaiaronga mahi tinana i te wa e uru ana koe ki roto i te waahanga honohono.

/ usr / bin / pwd

Kaore tenei i te tino awhina, no te mea kei te rere tonu koe i te whakahau kotahi engari kei te whai koe i te whakautu i muri ka oma i te aratau taunoa.

Ka rite ki te korero i mua, ka hiahia pea koe ki te whakauru i te mahinga -PP me -L.

Whakarāpopoto

He rua noa atu nga huringa mo te whakahau pwd:

Tuhinga o mua

Kei te whakaatu tenei i te tau putanga putanga mo te pwd.

A, no te rere ki te putanga anga o te pwd kaore pea tenei e mahi engari ka mahi ki te / bin / pwd.

Ko te panuku penei:

pwd --help

Ka whakaatu tenei i te whaarangi o te pukapuka ki te matapihi matatau

Ano kaore tenei e mahi mo te putanga anga o te pwd, engari ki te putanga / bin / pwd.
