There are two things you may have to address here: 1. path, and 2.
permissions.
1. Shells generally look at the environment variable $PATH (you can type
'echo $PATH') and if the current directory (also known as '.') isn't in
there then anything in the current directory won't be executed. To get
around this, you can add '.' to your path (type 'export PATH=$PATH:.')
or run the script as follows: './script.pl' or './script.sh'
2. For a file to be executed in the above manner, you have to make sure
the permissions for the file have the 'executable bit' set. Permissions
come in three basic sets: 'user', 'group' and 'other'. user refers to
the owner of the file, group refers to anyone in the group the file is
in, and other refers to everyone else. To make a file executable for
any of these sets, you set the executable bit for that set of users.
'man chmod' for some more info
but, for example, to give everyone permission to execute a file, you
would type 'chmod a+x script.sh'. If you type 'ls -al script.sh' you'll
then see something like
-rwx--x--x 1 iain iain 655 Jun 24 11:01 script.sh
^ directory?
^^^ user
^^^ group
^^^ other
and the rest of the line displays the actual owner, group, and some
other info.
This particular example shows that the owner (iain) can read (r), write
(w), and execute (x) the file, and everyone else can only execute (--x)
it. Note that 'x' is no good without 'r'.

If the file is not executable you can do this, otherwise you could just
say './script.pl'

This is very basic, there are lots of other things you will discover by
playing around, but I hope this gets you on the way!
