Bash Centos7“哪个”命令 [英] Bash Centos7 "which" command

问题描述

我意识到这可能是一个愚蠢的问题，但是我安装了Centos-7最小服务器，并且 which命令不存在或丢失。
我有一个需要它的脚本，但我找不到安装它的yum软件包。

I realize this might be a dumb question but I have a Centos-7 minimal server install and the "which" command does not exist or is missing. I have a script that needs it and I cannot find out what the yum package is that installs it. The code is below and is from a make file.

which grep > /dev/null 2> /dev/null

if test "$?" != "0"
then
    echo "\"grep\" command not found."
    echo "Installation is aborted."
    exit 1
fi

任何帮助将不胜感激...这是很难（即使不是不可能）

Any help would be appreciated... this is difficult if not impossible to google

推荐答案

要在CentOS中查找软件包，请使用 yum whatprovides ：

To find a package in CentOS, use yum whatprovides:

yum whatprovides *bin/which

在这种特殊情况下，该包称为其中，因此

In this particular case, the package is called which, so

yum install which

应该安装。
