hello!

i would like to know if the "ls" command can list the names of the existed expressions
or how can we know if a "NAMED" expression already exist, the same for a variable!.

it's just to be able to create it in case it doesn't exist! otherwise it will be edited.........

thank you.

string $exprs[] = `ls -type "expression" "*"` ;
