I have came across globbing patterns and wildcards and of particular interest to me is
This construct is similar to the
[!]construct, except rather than matching any characters inside the brackets, it’ll match any character, as long as it is not listed between the
rm myfile [!192]
The above I believe will remove any/all files, except for any/all files which have 192 in their name.
I am concerned however but the proper usage of this with a file extension, and in particular multiple conditions.
What would be the proper syntax in such a situation?
rm myfile [!.gif .csv. mp3]
rm myfile [!.gif !.csv !.mp3]
My worry is that the period might be misplaced, and so ANY file with a
. (which would be any of them surely?) would then be manipulated, when I am seeking to cause manipulation of specific files.
This construct is similar to the [ ] construct, except rather than matching any characters inside the brackets, it’ll match any character, as long as it is not listed between the [ and ].

Now; to me that suggests then a singular ! is sufficent, and all values therein after are contained within the range. But as they say, devil is in the details
