Command-line arguments
You are encouraged to solve this task according to the task description, using any language you may know.
Retrieve the list of command-line arguments given to the program.
Example command line:
myprogram -c "alpha beta" -h "gamma"
UNIX Shell
sh
To retrieve the entire list of arguments:
WHOLELIST="$@"
To retrieve the second and fifth arguments:
SECOND=$2 FIFTH=$5
Tcl
The pre-defined variable argc contains the number of arguments passed to the routine, argv contains the arguments as a list. Retrieving the second argument might look something like this:
if { $argc > 1 } { puts [lindex $argv 1] }
(Tcl counts from zero, thus [lindex $list 1] retrieves the second item in the list)
