I want to run program directly such as ./program without define the interpreter in shell first. so, how can i want to prevent this error?

bad interpreter: Permission denied

My operating system is redhat - CentOS release 5.6 (Final)

root@server [/tmp/mechanize-0.1.7b]# ./ 
-bash: ./ /usr/bin/env: bad interpreter: Permission denied
root@server [/tmp/mechanize-0.1.7b]#
root@server [/tmp/Python-2.7.1]# ./configure 
-bash: ./configure: /bin/sh: bad interpreter: Permission denied
root@server [/tmp/Python-2.7.1]#

Odd. Off-topic, but ... "have" /bin/sh and it is +x'ed? – pst May 21 '11 at 18:46

You're trying to execute programs from a partition mounted with the noexec option (likely /tmp). Either move them to a directory that is mounted with exec rights or use

mount -o remount,exec /tmp

(as root) to allow programs to be executed on /tmp. You can make this behavior persistent by removing the noexec option from /etc/fstab or your init scripts.

still not work root@server [/tmp/Python-2.7.1]# mount -o remount,exec /tmp root@server [/tmp/Python-2.7.1]# ./configure -bash: ./configure: /bin/sh: bad interpreter: Permission denied root@server [/tmp/Python-2.7.1]# – Gunslinger_ May 21 '11 at 19:32
@Gunslinger_ / could be mounted noexec, too. Can you give us the outputs of mount and ls -l /bin/sh? – phihag May 21 '11 at 19:50

Long-shot, but make sure that /tmp isn't mounted with the noexec mount option. That can give errors like that.
