Beggars can't be choosers. ;)

I'm not sure I would go with the fcntl.h interface, though. IIRC, ownership is based on PIDs, not TIDs, and although POSIX 1003.1d (previously 1003.4) changed that...

It violates the licensing to install Mac OS X on non-Apple hardware, IIRC.

However, on my MacBook Pro I have installed Leopard on an external (firewire) drive without any problem. Probably...

Thread synchronization is a big topic due to the various complexities involved. I agree with rr about where to look first. If you're coding on Linux, there is also the futex library which is worth...

From an engineering standpoint, yes. It would have to.

Most of the MTBF rates are based on some standard percentage of use, such as 30%. If you are keeping the drive busier than that, then you...

Nah, you're right. I didn't even notice this was the Solaris group. Sorry for the noise! :)

That depends. The Vixie Cron (written by Paul Vixie) on Linux systems does support an extension that uses the slash to indicate an interval.

Use output redirection.

If the input becomes large that may become slow. If so, post again here and we can talk about using sed, awk, or perl to accomplish this instead. (All three can do it and...

You first have to install the accounting package. You don't say which OS you're running, but I'll assume RedHat/CentOS. The RPM for that is sysstat. You'll need to read the documentation for it --...

The mDNS package (multicastDNS) thinks you're disconnecting from the network and reconnecting again. If the rest of the your network services disappear for a short time as well, then you may have an...

Unless you have an unusual environment, you can put "#!/bin/bash" (or some other full pathname to a shell) and then use that shell to write your scripts. It doesn't matter which shell the users log...

Yep, you're right. :b: I had a senior moment. (I thought there were vertical bars between each set of brackets.)

Thanks for replying and including the solution you ended up using. :)

Btw, that looks like C shell code due to the redirection syntax. You really don't want to use the C shell for any kind of...

Why did you choose to use the @() extended wildcard? That's not what the OP was asking for. In keeping with his (preferred?) formatting and structure:
if ls *.[Ll][Aa][Ss] >/dev/null 2>&1; then
...

Yep, exactly. And numbers 4 and 5 were the deciding factors for me to stop providing any help.

If he doesn't know where to get the information, he also won't have the authority to fix it. So it's probably moot. Time for him to call his sys admin support center.

Hmm. The "Not owner" message makes me think that the SSH server couldn't change the ownership of the pseudo-terminal to be the name you specified. Usually that means the user doesn't exist or the...

You don't say what operating system or shell this is using. I'm going to guess some distro of Linux and the Bash shell...


Check the filenames that your wildcard expands to. It's likely there's...

Not enough information. What OS are you using, what version of the cron daemon, what shows up in the cron log when a command fails, and so on...

Actually, it can be done, but it's a bit ugly.

The problem is that when you run the job in the background, it's the background shell that creates fd4 and the parent (your command line shell) will...

Go back and read (both of) my posts again. You didn't follow directions. ;)

Hey, that is pretty cool. :) One more reason to put Ruby on my list of languages to play around with...

Yep, if those are non-printing characters or escape sequences. Use the technique I listed above to enclose the Reverse and Normal strings and things should be fine. If not, post back here again.

No loops are needed:
my @a1, @a2, %diff1, %diff2;
@a1 = (1, 5, 10, 15);
@a2 = (5, 15, 25);

@diff1{ @a1 } = @a1;
delete @diff1{ @a2 };
# %diff1 contains elements from '@a1' that are not in...

Those settings look fine, but you didn't answer the question about your Bash prompt.

The Bash prompt requires \[ and \] around any non-printing sequence inside the prompt in order for Bash to...

Doesn't work on Mac OS 10.4.11, but strings found version 20040207; probably the BSD version on my machine and you've got the GNU version. I wonder if that's a significant factor? I'd be willing to...
