Calibre Platform Support - 2024

Platform Identifiers for Calibre Install Files and Runtime Directories

Calibre provides different executables that are optimized for different Linux distributions, and each has its own platform identifier. The platform identifier is sometimes referred to as a VCO, which refers to a Vendor-CPU-OS combination. The platform identifier is first used to identify which install files should be downloaded. After installation the platform identifier and release version number are used to identify the Calibre runtime directory, generally referred to as a MGC_HOME tree. Each Calibre MGC_HOME tree can only be used with specific OS versions and must run on hardware that supports the minimum CPU instruction set identified for that MGC_HOME tree. Note that when using Calibre with distributed processing, the MGC_HOME trees on the master host and all remote hosts must all have the same platform identifier.

Vim: Move Cursor With Command "f|F|t|T"

  • f命令移动到光标右边的指定字符上，例如，fx，会把移动到光标右边的第一个x字符上。F命令则反方向查找，也就是移动到光标左边的指定字符上。
  • t命令和f命令的区别在于，它移动到光标右边的指定字符之前。例如，tx会移动到光标右边第一个x字符的前面。T命令是t命令的反向版本，它移动到光标左边的指定字符之后。
  • 这四个命令只在当前行中移动光标，光标不会跨越回车换行符。
  • 可以在命令前面使用数字，表示倍数。例如，3fx表示移动到光标右边的第3个x字符上。
  • ;命令重复前一次输入的f, t, F, T命令，而,命令会反方向重复前一次输入的f, t, F, T命令。这两个命令前也可以使用数字来表示倍数。
