Pydf alternatiivne käsk "df", et kontrollida kettavärvi erinevates värvides
“Pydf” (Pythoni ketasfailisüsteem) on täiustatud käsurea tööriist ja hea alternatiiv Linuxi “df comandile”. Seda kasutatakse Linuxi failisüsteemides kasutatud ja vaba kettaruumi kuvamiseks, nagu käsk df, kuid erinevates värvides. Käsu pydf väljundit saab kohandada vastavalt teie vajadustele.
See käsk "pydf" on kirjutatud pythoni keeles, mis kuvab Linuxi ühendatud failisüsteemis kettakasutuse ja vaba ruumi hulga, kasutades erinevate failisüsteemi tüüpide jaoks kohandatud värve.
Pydfi installimine
Vaikimisi pole pydfi tööriista Linuxi distributsioonidesse installitud, peate selle installima kolmanda osapoole hoidla abil. Niisiis, kõigepealt käsk yum ”selle installimiseks.

Kuidas kasutada käsku pydf
Kui käivitate ainult käsku „pydf”, ilma argumenti määramata, kuvatakse selles koos kettaga ühendatud failisüsteemidega ainult teave kettaruumi kasutamise kohta.

Kuidas kohandada pydf-värve
Pydf-il on oma konfiguratsioonifail, kus saate määratleda oma kohandatud värvid, et anda väljundile lisatunnet ja ilmet.
# vi /etc/pydfrc
Lisateabe saamiseks lugege käsku pydf käsulehtedelt, vajutades terminalis sõna "man pydf".
