awk 无需手动输入

跑步怎么来man awk的No manual entry for awk？坦率地说，我从来没有亲自在我的 Archlinux 系统上安装过 Awk，但我刚刚发现当前的系统（我最后安装的系统）上没有 ，这很man awk奇怪。man gawk另一方面，工作正常。

有什么线索吗？

这是版本加上其他可能相关的输出：

$ awk --version

$ ls -l $(which awk)

$ which gawk
/usr/bin/gawk

答案1

从man man，手册页通常存储在/usr/share/man.

由于 Awk 有多种实现（gawk、mawk、 ...），因此它通常是指向要使用的真正 Awk 的符号链接，在您的例子中是 GNU awk。它的联机帮助页也是如此：

$ readlink /usr/share/man/man1/awk.1.gz
/etc/alternatives/awk.1.gz
$ readlink /etc/alternatives/awk.1.gz
/usr/share/man/man1/gawk.1.gz

检查是否可以在 下找到 Awk 链接/usr/share/man。

find /usr/share/man/man1 -path '*/awk*'

  • 如果是，则可能是链接损坏，在这种情况下，您可以将其删除并创建指向所需手册页的链接（见下文）。

  • 如果没有，则链接丢失。不知何故，你删除了它，或者它没有发货。这可能可以通过再次安装该软件包来解决。否则，手动创建符号链接：

ln -s /usr/share/man/man1/gawk.1.gz /usr/share/man/man1/awk.1.gz

手册awk页位于man-pages包中：

% pacman -Qo /usr/share/man/man1/awk.1p.gz
/usr/share/man/man1/awk.1p.gz is owned by man-pages 5.07-2

您必须显式安装此软件包：
