Why does the wildcard and GLOB pattern [A-Z] does not work as expected with 'ls' command ?

Solution Unverified - Updated -

Issue

  • If you have files created, say for example a, b, c and you want to list the files using the GLOB pattern as below :
[root@XXX ~]# touch a b c
[root@XXX ~]# ls -l [A-Z]
-rw-r--r-- 1 root root 0 Jul 21 19:31 b
-rw-r--r-- 1 root root 0 Jul 21 19:31 c
[root@XXX ~]# ls -l [A]
ls: cannot access [A]: No such file or directory
  • Now the issue is that inspite of giving a GLOB pattern [A-Z], we would expect only the files with name A to Z to be listed and not a to z.
