Bash – “Permission denied” when starting binary despite “rwx” priviledge

bashexecutablepermissions

I am trying to run the statistics software Stata 11 on Ubuntu 11.10. as a regular user and I get the following error message:

bash: xstata: Permission denied

The user priviledges seem ok to me, tough:

-rwxr-x--x 1 root root 16177752 2009-08-27 16:29 xstata*

I would very much appreciate some advice on how to resolve this issue!

In the ls output you can see the file owner(root) and group(root). The user priviiledges apply to file owner (rwx), file group (r-x) and others (--x). Because you are not the root (and I suppose that you are not in the root group), only other (--x) applies to you. Thus you can run the file, but not read it. As a quick fix, try chmod +r xstata, this gives the read permission to all.

According to the info provided you are trying to run 64-bit executable on 32-bit kernel. It won't work that way. You either need 32-bit binary or 64-bit kernel/glibc libraries.

Permissions Error: -bash: /dev/null: Permission Denied – How to Fix

Someone evidently moved a regular file to /dev/null. Rebooting will recreate it, or do

rm -f /dev/null; mknod -m 666 /dev/null c 1 3

As @Flow has noted in a comment, you must be root to do this.

1 and 3 here are the device major and minor number on Linux-based OSes (the 3rd device handled by the mem driver, see /proc/devices, cat /sys/devices/virtual/mem/null/dev, readlink /sys/dev/char/1:3). It varies with the OS. For instance, it's 2, 2 on OpenBSD and AIX, it may also not be always the same on a given OS. Some OSes may supply a makedev / MAKEDEV command to help recreate them.
