Write a perl script that processes the output of the echo $path shell command. this command displays the content of the
shell environment variable, $path. this variable contains a list of directory names. when you try to execute a command at
the command-line, the shell will look for the program file corresponding to that command in each of the directories listed in
the $path variable. your script should do the following:
1. execute the echo $path command. to execute a shell command in your perl script, see the example for the qx
quote operator on the "quoting operations" slides.
2. use a regex to extract the name of each directory in the output of the echo $path command.
3. print each directory name to stdout. print one directory per line.
note: you must use the m//g regular expression construct to extract all the directory names and store them in an array first.
here is an example to extract all integers in a string and store them in an array:
$s = "we had 3 clubs with 10 people each in 4 months.";
@arr = $s =~ /\d+/g;
