try wild carts!

like
Code:
$cat list?
or
Code:
$cat list??

i could get the combined output of list 1 2 3 with list 11 12 13 only by using
Code:
cat list? list??

or by using
Code:
cat list*

@akalya

actually ^ specifies it should start with "list"
incase if you have "alist" or "blist" etc.. ^ will be useful

found by INDHU again
