cl.exe (MS Visual C++) seem to wrongly send compile tome errors to stdout instead of stderr

It seems as if cl.exe would wrongly send the compiler errors to stdout instead of stderr.

What is the Perl equivalent of PHP's proc_open(), proc_close(), etc.?

Using PHP's proc_open(), I can start a process, read from STDOUT and STDERR (separately) an arbitrary number of bytes at a time using fread() while the process is running, detect when the process is done using feof() on the STDOUT and STDERR pipes, and then use proc_close() to get the exit code of the process. I've done all of this in PH...

bash redirect stdout and stderr to separate commands over ssh

I am using BASH 4. I am trying to find a way to legitimately prepend output to indicate the type of output that it is. I am able to do this with something kind of like this... ls -l /tmp/abcdefgh 2> >(sed 's/^/stderr: /') 1> >(sed 's/^/stdout: /') stderr: ls: cannot access /tmp/abcdefgh: No such file or directory ls -l /tmp/ 2> >(sed...
