There's a method of sorting -- I've seen it on a website and in a shell script -- wherein you give it a list and the site or script shows you only two options from that list, making you choose between the two. [more inside]
I'm seeking to write a shell script (probably using sed) that will be given some text and will abbreviate it for me. I've no need to reinvent the wheel, if such a shell script already exists. More inside. [more inside]
I have a podcast that downloads as multiple segments over multiple days. Its format arrives as YYYYMMDD_showcode_segment.mp3; so, for example, one download might result in files as 20090323_goofa_01.mp3 through 20090323_goofa_21.mp3, and also within the same download 20090324_goofa_01.mp3 through 20090324_goofa_21.mp3. What I'm looking for is a Unix script (shell, perl, what have you) that would look at a directory and look at what dates are represented there, and let me join all of the segments together by day. I can use mpgtx -j to do the actual joining; I'm looking for the code that would let the script determine what dates are in the directory and then get each day's segments united into a single MP3 for that day's show.
I would basically like to rip off, wholesale, some command-line script which will provide me a countdown -- only in days. No years, months, minutes, or seconds. Unfortunately, adapting an existing script is beyond my ken. [more inside]
