Compiled a C program, cannot run by name
I compiled a C program, but could not execute it using exec filename but only using exec ./filename Can I know why this is so? Thanks. -- Penguin #395953 resides at http://samvit.org subsisting on SUSE Linux 10.0 with KDE 3.5

Program names that doesn't include the path to the file are looked for in the directories listed in the environment variable $PATH. You do not have the directory where the program is in the $PATH variable Also, you don't need to use "exec" as a command to execute programs. Just ./filename will work, and you will still have a shell when it exits
Because "." isn't on your PATH, perhaps?
Did you really want to exec the program, or simply execute it?
Cheers,
Simon

Is the execute attribute set on the file?

And is the path to the file defined in your PATH variable (echo $PATH). Greg Wallace
