  • It stands for \u201crun commands\u201d.<\/li>\n
  • This comes from MIT\u2019s CTSS (Compatible Time-Sharing System) and Multics, where the idea that a command processing shell would be an ordinary program originated.<\/li>\n
  • CTSS had a program called RUNCOM (for \u201crun commands\u201d) and a script was called \u201ca runcom\u201d in the community where Unix originated, leading to the file extension .rc and generally to the rc abbreviation.<\/li>\n

    1.run commands
    \n2.resource control
    \n3.run control
    \n4.runtime configuration<\/p>\n

    In run control, ESR says so.<\/p>\n

    His footnote says:<\/span><\/strong><\/h4>\n
      \n
    • The \u2018rc\u2019 suffix goes back to Unix’s grandparent, CTSS.It had a command-script feature called “runcom”. Early
      \nUnixes used \u2018rc\u2019 for the name of the operating system’s boot script, as a tribute to CTSS runcom.<\/li>\n
    • “run commands” as the default long-form, but admits that context should determine word choice.<\/li>\n
    • While not historically precise, rc may also be pronounced as “run control”, because an rc file controls how a program runs.<\/li>\n
    • For instance, the editor Vim looks for and reads the contents of the .vimrc file to determine
      \nits initial configuration.<\/li>\n
    • The most sensible pronunciation depends on the function of the file: to start
      \nsomething up, or to control how something starts up.<\/li>\n<\/ul>\n[ad type=”banner”]\n","protected":false},"excerpt":{"rendered":"
