Why can't I run the executable on a flash drive (ubuntu)?

Question

linux

I'm trying to run the binary on a flash drive, but I get an error, I tried to write chmod +x showFilesAndExtInDir, nothing has changed, I can't even run it as root, what could be the problem?

ls -l for a file (I know I don't have run permission but I can't get it)
-rw-r--r-- 1 us us 2684759 Dec 29 16:15 showFilesAndExtInDir

mistakes

spoiler

I ran the full path (/media/us/Transcend/test_data_for_programs/media/video)
from the folder itself.

if ./showFilesAndExtInDir,
error: bash: ./showFilesAndExtInDir: Permission denied

if: bash ./showFilesAndExtInDir
error: ./showFilesAndExtInDir: ./showFilesAndExtInDir: failed to run binary file

Answer 1

Your flash drive is most likely FAT32.
FAT32 cannot store attributes, so the X bit is not there and cannot be. As a result, you will not run the binary from it.
Google says that it is possible to set permissions on the entire filesystem when mounted.

Answer 2

What is it written on? Is there a compiler in the system for this language?

Answer 3

Another option is to mount the flash drive with noexec options
. regardless of other conditions, it is not possible to launch an executable file from this partition.
one of the foolproof options.
