Running My Program Says "Bash: ./Program Permission Denied"

Running my program says bash: ./program Permission denied

chmod u+x program_name. Then execute it.

If that does not work, copy the program from the USB device to a native volume on the system. Then chmod u+x program_name on the local copy and execute that.

Unix and Unix-like systems generally will not execute a program unless it is marked with permission to execute. The way you copied the file from one system to another (or mounted an external volume) may have turned off execute permission (as a safety feature). The command chmod u+x name adds permission for the user that owns the file to execute it.

That command only changes the permissions associated with the file; it does not change the security controls associated with the entire volume. If it is security controls on the volume that are interfering with execution (for example, a noexec option may be specified for a volume in the Unix fstab file, which says not to allow execute permission for files on the volume), then you can remount the volume with options to allow execution. However, copying the file to a local volume may be a quicker and easier solution.

Attempting to run a Bash program results in permission denied error message

You have to add the execute flag to the file to execute it as ./BashCalculator.sh.

chmod +x BashCalculator.sh

If you want to put it in $PATH, either append the directory to it or place it in one of the paths of $PATH.

Also, enclose your question with three backticks to format it properly. This way it's better to read. You must update your question if you have additional information. Do not place such information in a comment (just as @Poshi commented).

Bash permission denied on Linux

It's the issue with your permissions. You currently don't have the permissions to execute the bof file.

To fix this, open the terminal and use the chmod command.

chmod +x /home/henry/Downloads/bof

This will give you the permission to execute the file. You can also use something like chmod 744 /path/to/file as an alternative. This will give you the permission to read, write, and execute on your account.

Check out linode documentation to know about file permissions.

Permission denied - Linux bash

check if you have permission for execution

ls -la a3.py

If not change the permissions

chmod +x a3.py

Obviously you need to add at the file start (within the Shebang Line) where is the python interpreter to run the script directly:

#!/usr/bin/env python3

Why do I get 'permission denied' after using ./file2 in Linux?

You are trying to execute a file and you do not have the right permissions for this. When you create a new Bash script with your text editor (let's say Vim), you should have the following permissions: -rw-r--r--. As a user, you can then read and write this file, but you cannot execute it with ./.

1. If you want to execute a file without changing permissions, you can use the following command: bash myFile.sh.

2. If you want to execute a file with ./, you will have to modify permissions. Something like that is OK: chmod +x myFile.sh.

3. If you do not want to struggle with ./ and prefer to call myFile.sh from anywhere like other built-in commands, move the executable file in a directory that is in your PATH. /usr/local/bin should be a wise choice. Check your PATH with echo $PATH, just in case...

Ubuntu:: ./program: Permission Denied

Type gcc --help to see some help.

-c                      Only run preprocess, compile, and assemble steps

This means that, when run with this option, GCC doesn't link the executable with any (even system) libraries.

In short, to run a program, the OS needs a starting point, which is located in some system library. Since in your case GCC isn't linking the executable with anything, the OS doesn't know how to run the file, where to start.
