In a different discussion on this site [see Redirecting input in a shell script] a visitor commented that “I was too busy trying to make sure the above post made sense that I forgot to ask for help. If you can, please post examples of how I can make the second argument a requirement and evaluate if it is a number. Thank you in advance!”

Linux Shell Script Programming
Can I sequentially rename files in Linux?
As part of some user interface testing I’m involved with on an Ubuntu Linux system, I find myself frequently having to rename groups of files in a sequential manner. That is, I’ll have files like “output mm-dd-yyyy at hh:mm:ss” and need to rename them to “testrun-xx-file-yy”. Is there any way to automate this so I don’t have to go crazy typing?
Why is shell script programming so fun?
Dave, can you tell me, how come I enjoy shell programming more than other types of programming (Javascript, Java or C)?
How can I keep a compressed Linux archive up to date?
We have a situation where we need to keep a ZIP archive of some data files available on our Ubuntu Linux server so that our satellite offices can grab the information through slower data lines. Problem is, the underlying files change 2-3 times a day. What’s a quick, efficient way to only rebuild the ZIP archive file on our Linux system if a file’s changed, but leave it as-is if everything’s stayed the same?
How do I find out what searches people did to end up on my Web site?
I’ve been trying to figure out whether there’s a way that I can automate digging through the “referrals” on my site so I can see what searches people did to end up on one of my Web site pages. I’m running a Linux server and have Apache installed, so I get a huge log file with tons of info. But what I’d love is a simple script that will let me get email once a week with a sorted list of what searches people did to get to me. Doable?
How can I convert map addresses into latitude longitude?
I’m trying to write a shell script that will accept a street address and output the latitude and longitude of that address, for geocache purposes. How can I do that?
How can I bulk rename Apple iPhone screen captures?
As part of my work, I take tons of screen captures on our test Apple iPhone for documentation, but my boss wants me to use SEO friendly file names and it’s a huge hassle to rename them one by one. Is there some sort of script I can use on my Mac to fix things?
How do I analyze word use in a document or book?
I’ve got a bet with my husband and you need to help us settle it. I was reading Jane Austen’s “Pride and Prejudice” and he said “I bet you $20 that “pride” shows up more than “prejudice” in that book.” I think he’s wrong, but have no idea how to figure it out. Can you help?
