Linux entry-based wildcard characters

Globbing: File name wildcard mechanism (this is the whole file name match, not part of the file name)//Note here refers to the filename

Matching mode:

*: matches any character of any length

pa*: All files starting with PA, *pa*,*pa,*pa*a* pa,paa,passwd

?: matches any single character pa??? Pa,p?a,p?a? PA (not compliant with PA?), paa,passwd

[]: matches any single character within the specified range

There are several special mechanisms [A-z] (default is case insensitive), [A-z] (default is case insensitive), [0-9],[a-z0-9][[:upper:]]: All uppercase letters//only match one uppercase letter

[[: Lower:]]: All lowercase letters

[[: Alpha:]]: All letters

[[:d Igit:]]: All numbers

[[: Alnum:]]: All letters and numbers

[[: Space:]]: all whitespace characters

[[:p UNCT:]]: all punctuation characters

[^]: matches any single character outside the specified range

[^[:upper:]]: Match non-uppercase characters

[^0-9]: matches any non-numeric character

[^[:alnum:]]: matches any non-normal character

Note The writing format two curly braces are in a specific format, and wildcards can be used to quickly and efficiently find and match any letter and number as well as punctuation.
