Vgersh is very good at this type of problem and I don't want to but in, but most cases, in most shells, using an array to store the data and exploding the array is a simple way to form a...

Hello,



This is one of the well known *nix gotchas.
Most unix systems programmers have gotten used to it.
Not that it's ideal.

Good luck.

You stated that you don't want to set O_NONBLOCK
which is standard to *nix for alleviating blocking behaviors
and is the basis for fast event interfaces like kqueue and
epoll for...

Since you are driving the interaction remotely and possibly dealing with multiple logins concurrently the way I'd do this is to use an interact for each spawn_id (after successful setup) with a...

Ouch. I could probably advise but your outlined procedure is very wrong.
If all in tcl this will require a moderate amount of work and very little expect as
explained.

An option is expect for windows.

Using getopts would be a better bet imho.
-g group, -u user -r (optional regexp)...that kind of thing.

Just for contrast on a modern intel SMP processor running linux 2.6.18 I get more

On that basis I don't believe this qualifies as a bug..more of a growing pain. ...

Linux pthreads don't support these functions. I'd suggest man -k pthread_cond.
These functions can be recreated without too much trouble.

Not to be a wiseacre but this doesn't seem to have a lot to do with HLP.

Both ways would work for the op. it seems to me one involves creation of a state machine and the other depends on avoiding serialization blocks imposed by pthread_join.

If you are handling clients on a system that must scale you will use neither. Using non-blocking I/O and a fast event mechanism like epoll or kqueue is a better answer.

man sigprocmask.

The normal threaded way to do what is suggested is to create a monitor thread for notification and use pthread_cond primitives for the synchronization.
Example code follows.

wsiefkas,

You can use ssh's pki (keys) to facilitate interaction from a shell script. Simply look at the man pages for : ssh-add, ssh, ssh-agent, ssh-keygen, sshd, etc.. for details. This does ...
