linux - 如何将 Linux which 命令的输出通过管道传输到 Linux 文件命令中？

Question

$ which file
/usr/bin/file
$ file /usr/bin/file
/usr/bin/file: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped

为什么这不起作用？

$ which file | file

Usage: file [-bcikLhnNrsvz0] [-e test] [-f namefile] [-F separator] [-m magicfiles] file...
   file -C -m magicfiles

尝试 file --help 获取更多信息。

Answer 1

您可能正在寻找 xargs 或 shell 扩展。尝试:

$ which file | xargs file

或

$ file `which file`
