#### 17.4.9 cat

Command: cat [`--dos`] file ¶

  Display the contents of the file file. This command may be useful to remind you of your OS’s root partition:

      grub> cat /etc/fstab

  If the `--dos` option is used, then carriage return / new line pairs will be displayed as a simple new line. Otherwise, the carriage return will be displayed as a control character (‘`<d>`’) to make it easier to see when boot problems are caused by a file formatted using DOS-style line endings.

  Note: `cat` can be used to view the contents of devices using the block list syntax (see How to specify block lists). However, it is not advised to view binary data because it will try to decode UTF-8 strings, which can lead to some bytes missing or added in the output. Instead, use the `hexdump` command (see hexdump).
