Chmod +x filename

1

I give chmod +x filename and and run the file
[paul@RHEL4a ~]$ echo echo Hello World > hello_world
[paul@RHEL4a ~]$ chmod +x hello_world
[paul@RHEL4a ~]$ ./hello_world
-bash: ./hello_world: Permission denied

I get this error.

Please run it as “sh hello_world” as mentioned on our FAQ
