===Wildcard characters===
Like other operating systems, AmigaDOS also provides [[wildcard character]]s that are substitutes for any character or any sequence of random characters in a string. Here is an example of wildcard characters in AmigaDOS commands:

<syntaxhighlight lang="doscon">
1> Dir #?.info
</syntaxhighlight>

:searches the current directory for any file containing ".info" at its end as suffix, and displays only these files in the output.

The parsing of this is as follows. The "?" wildcard indicates "any character". Prefixing this with a "#" indicates "any number of repetitions". This can be viewed as analogous to the [[regular expression]] ".*".
