I am writing some simple "Hello world" C code. I am logged in as the ROOT user. After I save the code, I compile the code (gcc <filename.c>). Next I try to execute the code (a.out <filename>), but I am then greeted with

'bash:aout is not a valid command or directory.'

Granted the code works fine when I log in as a regular user... What gives???


Thanks

the PATH environment variable typically associated with the root user differs slightly from that of an ordinary user.

the root PATH env variable will usually contain additional directories such as /sbin and /usr/sbin. Another major difference between root and user is that the user PATH variable includes the PWD in the path or the "./" entry meaning current directory.

root's PATH env variable does not contain ./ in its path.

so as root to execute a.out you will probably have to type it as such...

./a.out <filename>

hope that helps.

okay, I will try it... thanks for the insight...

Peace
