AIX : cannot execute binary file, 0403-006 execute permission denied

Question

I am working on AIX 7. I like to know more in detail about the following error scenarios

• cannot execute binary file
• 0403-006 execute permission denied

---

for the first case, on search it was likely that,

when you are trying to run 64 bit software on a 32 bit OS, you may have that error. AIX is 64 bit, and I have been trying to use mysql by installing XAMPP, where I am getting the above error. I assume 32/64 bit software will be okay with 64 bit OS.

for the second case,

though I have logged in as a root, and file permissions are 755 [ -rwxr_xr_x ] execution permission is denied..

I will be very happy, if I could know why the above situations occur and the best way to resolve it.

Thanks in advance !!

Answer 1

Use ls -l to list the permissions for your files in the directory

If the file concerned does not have x (execute) you need to add it

chmod a+x myfile.sh
