This is just a little script to look up errnos (symbolic or numeric) in /usr/include/sys/errno.h.

The usage is as follows:

errno [ number | name ] ...

For example: 

	$ errno 7 8 9
	errno 7 is E2BIG - Argument list too long 
	errno 8 is ENOEXEC - Exec format error 
	errno 9 is EBADF - Bad file descriptor 

	$ errno EISDIR
	errno 21 is EISDIR - Is a directory 

	$ errno 95
	errno 95 not found in /usr/include/sys/errno.h
