Bad interpreter

Arnaudo_Massimo · 5 January 2003 16:25

Hi everibody,
i would start a test.rb file. I can if a type:

masarn1@gull:~$ ruby test.rb
hello, World il mio nome è Massimo

but if i type:
masarn1@gull:~$ ./test.rb
bash: ./test.rb: /usr/local/bin/ruby: bad interpreter: Permission denied

Now.
masarn1@gull:~$ which ruby
/usr/local/bin/ruby

masarn1@gull:~$ ls -l /usr/local/bin/ruby
lrwxrwxrwx 1 root root 13 dic 24 19:45
/usr/local/bin/ruby -> /usr/bin/ruby
masarn1@gull:~$ ls -l /usr/bin/ruby
-rwxr-xr-x 1 root root 3136 mar 20 2002 /usr/bin/ruby
masarn1@gull:~$

Why this not work?
Any suggestions?

Best Regards.
Massimo

Check the permissions on test.rb itself, not just the Ruby executable.
Bash erroneously reports a bad interpreter error whenever the script
itself is not executable. (There may be another reason, but this is the
most common problem.)

Maybe you imported the file from win/dos , and you’re having problems
with the termination character, this is a problem with your shell, I
supopose

No, i have created and edit where it is: home directory in linux

The strange thing is that when i exec it from root user, it do not
works:

masarn1@gull:~$ su

1)Check where is your ruby interpreter
(from the shell : “which ruby”).

Maybe you have another one in your path , and no perm over it.

maybe try

#!/path/to/env ruby

instead of

#!/path/to/ruby

as

the first line of the script.

O il contrario

(last :

[loser@irc ted]$ ./tst.rb
bash: ./tst.rb: bad interpreter: No such file or directory
[loser@irc ted]$ cat tst.rb
#!ur/local/bin/ruby
puts "hello world
[loser@irc ted]$

Now, the path to ruby is wrong , I don’t get your same error, but
trying costs nothing

Maybe ruby is not in /usr/local/bin. Or it is not in your
PATH environment var, so #!/usr/bin/env ruby failed

Thinks to check:
$ whereis ruby - will give you full path to ruby
$ ruby ./test.rb - is ruby in your PATH environment var

Maybe correction of first line in the script will be needed:

— test.rb —
#!/put/here/the/right/path/ruby

What happens when you call /usr/local/bin/ruby straight from the command
