shell command

Just write a single shell command without any pipes to list all those files
in the current directory whose filenames are just two characters long.?

is this a doubt or jus for knowledge sharing purpose ???

ls ??
should work?
but its not working

find . -name ?? -print
wud this work !!

the find command is wrong. You need to use "-maxdepth 1" to limit the search to the current directory.
If you only want to look at files, then use "-type f". You main mistake is that the ?? should be inside double quotes.
You want:
find ./ -maxdepth 1 -type f -name "??"

If you have 3 files; aa, bb and cc in the current directory and try to run
find ./ -name ??
You are really entering the command:
find ./ -name aa bb cc
because of file globbing by the shell.
ls ?? will also not work
there is also a very simple command that will do the job ?
