Basically I ran the following as a test:
$ gcc -c -xc - -o /dev/stdout <<<'int main(){return 0;}'
I got an error (Fatal error: can't write /dev/stdout: Illegal seek), and I then found that (presumably as a clean-up step) gcc deleted /dev/stdout. Now when I run for example echo foo > /dev/stdout, it just creates an ordinary text file at that location.
Can I just create it again as a symlink?:
$ ln -s /proc/self/fd/1 /dev/stdout
Or is there more to it than that?
How can I prevent this from happening again? I realize that /dev/stdout needs to have write permissions for everyone for it to work properly.
