### So in this case you have to pass in a parameter
|
|
### Any parameter you type will work
|
|
### If you don't type a parameter you get an error
|
|
###
|
|
### The syntax for this is
|
|
### noflag hola
|
|
###
|
|
|
|
def noflag [x] {
|
|
echo $x
|
|
}
|
|
|
|
### The syntax for this is
|
|
### flag -f
|
|
### flag --flag
|
|
|
|
### If you type anything else it does not work
|
|
### For example
|
|
### flag -flag
|
|
### flag -f=hola
|
|
### flag -f hola
|
|
### flag -f = hola
|
|
|
