Linux: find file names with 4 or 5 characters
How can I find file names consisting of either 4 or 5 characters?
For file names with 4 characters, I can use find . -name ????.tgz, but how to I expand this to length either 4 or 5?
find . -name ????.tgz
Is there a better way of doing than using two finds with an operator in between?

It only takes one find invocation...

Please avoid "Give me the codez" questions. Instead show the script you are working on and state where the problem is. Also see How much research effort is expected of Stack Overflow users?

@jww You didn't read the question carefully. OP did write a
find command (it's just not formatted correctly).– oliv

Here is one solution:
find . ( -name "????.cpp" -o -name "?????.cpp" )
-o is for logical OR
-o
just replace .cpp with .tgz or whatever you want. There is also this regex version that would do the same thing:
.cpp
.tgz
find . -regextype posix-egrep -regex '^./[a-zA-Z]4,5.cpp$'
in regex ^ is start symbol ^./ means starts with ./. [a-zA-Z]4,5 means followed by 4 to 5 characters, . means . where is escape character .cpp$ means ends with .cpp
^
^./
./
[a-zA-Z]4,5
.
.cpp$
.cpp
If file name contains numbers instead of [a-zA-Z] do [a-zA-Z0-9]. So it will look like this:
[a-zA-Z]
[a-zA-Z0-9]
find . -regextype posix-egrep -regex '^./[a-zA-Z0-9]4,5.cpp$'
This will match files like
foo.f.bar– oliv

foo.f.bar
@oliv it does not batch foo.f.bar, but there is a mistake :(. It matches

./dddd/cpp
shopt -s extglob globstar
printf '%sn' **/?????(?).tgz
extglob
globstar

?(pattern-list)
Or simply:
printf '%sn' **/????.tgz **/?????.tgz
You could use this find command:
find
find -type f -regextype egrep -regex ".*/[^./]4,5.[^./]+$"
The regular expression is set catch any basename file with 4 or 5 characters.
Note this regex applies on the full name, including path.

If you can use find to get all files with 4 character long names, and use it to get all files with 5 character long names... well... it does have an or operator that would let you get both.
