Cov txheej txheem ua haujlwm feem ntau siv kev hloov pauv ib puag ncig txhawm rau txheeb xyuas ntau yam kev teeb tsa hauv ntiaj teb uas cuam tshuam rau ib feem ntawm qhov system, lossis los tswj cov ntawv thov. PATH qhov sib txawv yog ib qho ntawm qhov hloov pauv ib puag ncig, thiab feem ntau siv tsis muaj tus neeg siv kev paub. Qhov sib txawv no tuav cov npe ntawm cov npe uas yuav siv los ntawm daim ntawv thov (tshwj xeeb yog cov plhaub) txhawm rau tshawb nrhiav cov lus txib.
Kauj ruam
Kauj Ruam 1. Paub cov ntsiab lus ntawm PATH sib txawv los ntawm kev nkag mus rau qhov hais kom ua "ncho $ PATH" hauv lub plhaub qhov rai
Koj yuav pom cov npe ntawm cov npe raws li qhov piv txwv hauv qab no:
- uzair@linux: ~ $ ncha $ PATH/home/uzair/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/games
- Nco tseg: phau ntawv teev npe hauv $ PATH kuj sib txawv tau muab cais los ntawm ":".
Kauj Ruam 2. Ntxiv cov npe ":
/sbin "thiab":/usr/sbin "ib ntus rau PATH cov npe nrog cov lus txib hauv qab no:
uzair@linux: ~ $ export PATH = $ PATH:/sbin/:/usr/sbin/
Kauj Ruam 3. Muab cov ntsiab lus ntawm PATH sib txawv los lees paub tias qhov kev hloov pauv tau tshwm sim
- uzair@linux: ~ $ ncha $ PATH/tsev/uzair/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
- Nco ntsoov tias cov kev hloov pauv saum toj no tsuas yog ib ntus thiab yuav ploj mus thaum lub khoos phis tawj rov pib dua.
Kauj Ruam 4. Sim khiav lub app uas nyob hauv PATH tshiab kom ntseeg tau tias koj qhov kev hloov pauv tsis ua teeb meem
