This solution works: ifconfig eth0:0 <ip> netmask <mask> up ip route replace default via <ip> but sometimes the second call gets an error "network unavailable". Adding a sleep between them fixes it, but is unreliable. What i...

I have potentially large files that need to be sorted by 1-n keys. Some of these keys might be numeric and some of them might not be. This is a fixed-width columnar file so there are no delimiters.

Anything anyone out there is using to do this? Is...

Some people use ma...

That is the EAGAIN code, which is the same as WOULD BLOCK which means there is no data waiting to be read, but select is returning 1 saying there is data (tested in Linux): #include <time.h> #include <unistd.h> #include <stdio.h> #include <stri...
