It gives the first file... Not the wildcard argument.!!!
It seems that the wildcard is being interpreted by being the "$1" argument!
So feeding wildcards to a script just doesn`t work! Period!


Well isn't that curious!

Code:
./script "t*"
WORKS

so you would think that if you build a wildcard parameter with single quotes around it - like this -

Code:
# w='"t*"'
# echo $w
"t*"
#
would do the trick - but no -

Code:
./script $w or "$w"
FAILS

Enclosing in single quotes turns off expansion of wildcards -i mean the outer quotes. This: "'$var'" would still get expanded. Sometimes you have to escape characters to keep them from being immediately expanded by the shell: \$var
