I’m working on an assembly program using NASM on Linux. The program is supposed to open a file (which is located in the same directory and has all necessary permissions) and process its contents. However, when I run the program, it fails to open the file and outputs the following error:
Error: Could not open file.

What the Program Should Do:
Check if a file name is provided as a command-line argument.
If no file is specified, print an error message and exit.
Attempt to open the specified file for reading.
If the file opens successfully, read its contents, locate the second line, and print it to the standard output.
If the file cannot be opened or read, print the corresponding error message and the error code.
The Issue:
Even though the file exists in the same directory and has read and write permissions, the program fails to open it and displays the error message:Error: Could not open file.
