Full Discussion: Object matching with Wildcards
Top Forums Shell Programming and Scripting Object matching with Wildcards Post 302659933 by Scrutinizer on Thursday 21st of June 2012 04:24:00 PM

It was not meant as a solution, but to show you what would happen...

It would only work with single brackets, and only if there are zero or one files. With two or more files the test will fail. This is because the shell expands the wildcards (?) first:

Code:
touch abc123456 
$ if [ -f abc?????? ]; then  echo hello; fi
hello
$ touch abc123456 abc123421 abc765432
$ if [ -f abc?????? ]; then  echo hello; fi
-bash: [: too many arguments

If we use set -x, it becomes clear why:
Code:
$ if [ -f abc?????? ]; then  echo hello; fi
+ '[' -f abc123421 abc123456 abc765432 ']'
-bash: [: too many arguments
$

within double bracket the wildcards do not get expanded so the test will always fail unless a file with the literal name exists:
Code:
$ touch 'abc??????'
$ if [[ -f abc?????? ]]; then  echo hello; fi
hello
$
