[SOLVED] Problem running scripts

[YuGiOhJCJ]

Hello,

When I try to run a script like this, it failed:
$ ./hello_world.sh
bash: ./hello_world.sh: /bin/sh: bad interpreter: Permission non accordée

I must run the script like this:
$ bash ./hello_world.sh
Hello World!

This is the script:
$ cat hello_world.sh
#!/bin/sh
echo Hello World!

These are the permissions:
$ ls -l hello_world.sh
-rwxr-xr-x 1 yugiohjcj yugiohjcj 28 Sep 25 18:23 hello_world.sh

And this is my user identity:
$ id
uid=1000(yugiohjcj) gid=1000(yugiohjcj) groups=20(dialout),24(cdrom),25(floppy),29(audio), 44(video),46(plugdev),1000(yugiohjcj)

Can you explain me why I can't run this script like the first try?

Thank you.

Hi YuGiOhJCJ

Check your script...

This is the script:
$ cat hello_world.sh
#!/bin/sh
echo Hello World!

You should have #!/bin/bash in place of #!/bin/sh.

The second attempt works because you force bash to be the interpreter.

It doesn't resolve the problem.

This is the new content of the script:
$ cat hello_world.sh
#!/bin/bash
echo Hello World!

And when I try to run it like this:
$ ./hello_world.sh
bash: ./hello_world.sh: /bin/bash: bad interpreter: Permission non accordée

But if I run it like this:
$ bash ./hello_world.sh
Hello World!

Can you help me to run my script like the first try?

I found the solution on the Internet: edit my /etc/fstab file.

I must replace this:
eeepc.geekdomain:/home /home nfs defaults,user 0 0
by this:
eeepc.geekdomain:/home /home nfs defaults,user,exec 0 0

The 'exec' option is what I need

Problem resolved.
