    • Examples

    Use the "whereis" command to check the location of the "bash" command. Enter the following command:

    $ whereis bash

    After executing the above command, the output information is as follows:

    bash:/bin/bash/etc/bash.bashrc/usr/share/man/man1/bash.1.gz

    Note: The output information above from left to right is the queried program name, bash path, and bash's man manual page path.

    $ whereis -b bash 
$ whereis -m bash

    The output information is as follows:

    $ whereis -b bash               #显示bash 命令的二进制程序  
bash: /bin/bash /etc/bash.bashrc /usr/share/bash    # bash命令的二进制程序的地址  
$ whereis -m bash               #显示bash 命令的帮助文件  
bash: /usr/share/man/man1/bash.1.gz  #bash命令的帮助文件地址
