No such file or directory - yet, file is there

[southbeach]

hello!

What would cause Linux (Ubuntu) to emit an error "No such file or directory" when attempting to execute a file that is listed when using ls -l?

Command file [FILE-NAME] also finds the file and defines it as executable ... I just cannot execute it.


Thanks,

Assuming you're doing this from a command prompt are you preceeding the filename with a "./"? Unless the current directory is defined in the path one must explicitly provide the path to the current directory. Therefore filename would be executed as ./filename
Also, when look at the output of ls -l filename is the file executable? You could try that with the
"sh ./filename " command.

Good luck

from command prompt
logged in as root ( I unlocked it )
using ./[FILENAME] or just [FILENAME] same error
sh ./[FILENAME] gives me Syntax error: "(" unexpected (no idea why this would be, it is not a plain text script)
file mode is 755

The 'No such file or directory' could be output from your command. It could be running fine. Is it maybe not finding a file it needs?

If it's not finding the command itself, bash would give you this as output...

$ my_command
bash: my_command: command not found
$

Other shells give similar output.

The '(' unexpected is common when trying to run a compiled program as a parameter to a script. That just means it's not a script and you can't run it that way.

Try using the '[tt]strace[/tt]' command to see what file(s) it's trying to open. Something like this maybe...

$ strace my_command

See [tt]strace[/tt] man page for more info.

Firstly it would help to know what the file is, where it came from and how you are calling it?

Is it the correct version for your OS 32bit or 64bit?

Lets see the actual output from when you try and run it we may recognise the problem.

As Sam says above use strace to identify exactly what its doing it will help to use the -o option to push the results to a file and let us see here so we can help.

Good luck

try ls -la
my first guess is that it is a symbolic link to a non-existent file

(ln -s does not check the destination exists when it creates the link)

This will give you all the "open"s and their results...

strace my_command 2>&1 | grep open
