“apt depends”在哪里記錄？

Question

“apt”的子命令“depends”在哪里記錄，尤其是它的 output 格式和 output 中 pipe 符號的含義？

“man apt”根本沒有提到這個子命令。

示例調用：

$ apt depends inxi
inxi
  Depends: pciutils
  Depends: procps
  Depends: <perl:any>
    perl

它記錄在apt-cache聯機幫助頁中：

depends pkg...

depends shows a listing of each dependency a package has and all 
the possible other packages that can fulfill that dependency.

pipe的含義| 是或，在您的示例中：

 |Suggests: wget
 |Suggests: curl
  Suggests: libhttp-tiny-perl

可以翻譯成：

Suggests: wget or curl or libhttp-tiny-perl

和

 |Suggests: libcpanel-json-xs-perl
  Suggests: libjson-xs-perl

可以翻譯成：

Suggests: libcpanel-json-xs-perl or libjson-xs-perl
