Re^2: use: command not found error

One route on unix systems for the "where is this user's perl?" is to use:

#!/usr/bin/env perl

which gets whatever the user would get by typing "perl" at the command line. There may be multiple perl versions in different locations, leading to strange behavior. If /usr/bin/env is not there, there are bigger problems.

If /usr/bin/env is not there, there are bigger problems. Indeed this is often debated, and many think that `env` suffers from the same problem it aims at solving.	[reply] [d/l]

i have the same problem - i want to run the following perl script helloworld.pl #!/usr/bin/perl print "Hello World!\n"; it runs if i type perl helloworld.pl in the command line but, if i try to run the script without calling perl explicitly in the command line (i.e. helloworld), i get "command not found". i'm absolutely sure that i'm running the program from the correct path and that perl is located in /usr/bin/ - i used which perl. what's going on guys?
