Wonderful! Now let me ask one more question: Examples of "XPATH" don't quite correspond to examples I see, so tags like "/first/second/third" from a body of XML that looks like:

<first>
...

One of my biggest concerns is the size of the file we're looking at -- 3.5Gig. I've been told that xmllib2 has problems with files that are around a few hundred lines. Is XMLSTARLET fairly stable...

As a complete newbie to XML, I need help with xmlstarlet. That particular line is just an example of one of the values I need to extract. I don't understand the syntax of how to use xmlstarlet to...

We got data that was supposed to be CSV, but was sent in a huge XML file.

I've downloaded xmlstarlet, but I'm darned if I can get it to operate the "sel" feature to look down a path and get any...

Great -- first, our topology is that we have a cable modem from Comast that goes to our business router (also from Comcast) to our machines. Our owned IPs that we have trouble with are public IPs...

First point -- absolutely.

Second point -- okay -- gets more complicated when I'd hoped for a simple fix ( :-) )

Third point -- no, if one path fails, I'd have ALL users go to the proxy, and...

Agreed. Is there a preferred way of doing that? Or just start an independent thread and close this one?

The main servers are Redhat. The client laptops are windows and OS X.

Actually, no. But it's intermittent -- annoyingly so. Comcast has reached out, but unfortunately left no number to get to the person handling it. Bottom line is that I simply want a backup...

The machine I'm using to forward SSH/SFTP is a Linux box.

Well, that's certainly worth a try. Unfortunately, while we've been discussing this, the problem has gone away, so I'll have to wait for the next outage.

I assume that every proxy may or may not...

So you're saying that it's not possible to use the server I'm currently using for SSH/CLI access to do something similar for HTTP? Or far more complicated?

Well, I have to assume Comcast will fix this eventually, so I'm not interested at the moment in solving that problem, only getting a workaround.

It's ONLY a problem for those particular IP...

We have a bank of static IPs we purchased from Comcast, and we have been dealing with loss of access for a long time and applying all sorts of bandaids, from new routers to having a tech come in to...

We cannot access our local servers from our LAN, but we CAN access them from everywhere else!

Every once in awhile, our local access to our servers drops, but if I SSH into an external Linux...

I don't see the code I posted with changes yesterday for some reason. However, I did find the problem. I copied the tested code from OS X onto our Redhat server, and on the new machine, invisible...

There is no output now. If it were an output format or content problem, I could fix it, but no such luck.

I added some fields to some existing code, and all was well. Just added a few more, and BAM. I've looked this over forever, but being a newbie to Python, I see NOTHING. The code generates syslog...

I've got this program set up so that it creates files whose unique names specify the jobs their contents describe. In order to retrieve the information inside those files, I have to do a "grep" and...

This sounds great! Thanks!

I'm not sure I understand the mkdir command, tho', since I'm talking about creating
a file, not a folder. I'll have to look into this and see how it pertains to...

I have a system that uses file access to manage parallel processes. Each process checks to see if a file with a unique name that corresponds to the job it's got to do exists. If it does, it exits. ...

I've got a BASH script that runs much faster from the command line than when invoked under CRON.

Ideas? Priority? IO?

Unfortunately we built the database custom as well, so we'll have to test out the capacity. In reference to another comment, each job does six queries, and they're not very time sensitive at all. ...

In my case, "my_job" does some database queries and decides to call a function that will result in a cross-processor message and then wait for a result to be returned.

I would still benefit from a...

Some of the coding decisions I've made are to allow rapid prototyping and debugging, such as "read" statements in the loop to allow me to step through it slowly. Eventually this will all be removed...
