How Do I Fix the \'bash: ./program Permission denied\' Error?

"bash: ./program Permission denied" Issue Resolved

When executing a program on a different computer, you may encounter the error "bash: ./program Permission denied." This issue arises due to missing execute permissions.

To resolve this, follow these steps:

Modify Execute Permissions:

• Navigate to the directory containing the program.
• Use the command chmod u x program_name.
• This grants the user execute permission for the specified program.

Copy to Local Volume (Optional):

If the previous step doesn't work, try the following:

• Copy the program from the USB device to a local volume on the computer.
• Repeat step 1 to grant execute permission to the local copy.

Understanding Execute Permissions:

Unix-like systems require execute permission to run programs. Copying files between systems or mounting external volumes may sometimes disable this permission as a safety measure. chmod u x allows the file owner to execute it.

Additional Considerations:

• If security controls on the volume are interfering with execution (e.g., a mount option), remount the volume with options that allow execution.
• Copying the program to a local volume can often be a simpler solution.
