The scripts often contain tabs or other odd characters so they cannot be pasted. You have to do a "save link target as" to a directory on your PATH and make the script executable. If you are using an iPad, or merely want to look at a script you can use the "(see it)" link by the download link.

Alternatively, you can get them or see them on my github page.

back to contents -- mail notifier watches an IMAP account and alerts you with a beep and a very small pop-up when new mail arrives. It takes up no permanent screen space. Here is a snapshot of a corner of my workspace showing the pop-up: message
I start in my .bash_profile and stop it from my .bash_logout.

cdm -- cd from menu (see it) displays a menu like this:
menu in xterm
and lets you choose the directory you want by name or by number. (In the screenshot, the reply has been copied -- not typed!) Directories can be omitted from the menu, or added, by setting up a couple of hidden files.

sfmv -- safe mv command

sfmv is better than the standard mv command's --no-clobber option because it gives an error message when it doesn't move a requested file.

getPids -- get PIDs from BBC schedules

getPids extracts programmme IDs from the BBC schedules using a Python parser to unravel the HTML. getPids has been tested with Python 2.7 and Python 3.5 on Linux, and with Python 3.6 on Windoze 7.

getPids -6 bbcone hd -- would put a week's BBC 1 (HD) TV schedule onto standard output. The week here comprises today and the six previous days. You can see past and future days.

SFTP -- transfer and compare files on remote systems with SSH

SFTP is a convenient front-end to the sftp command; it can be used from the command line to move files about or compare them, or it can be called from cron or from any shell script. SFTP uses the batch mode of sftp but you don't have the hassle of setting up a batch file or reading all the output. Clearly, it is only useful if you have set up password-less logins.

SFTP works with SSH, Open-SSH and Sun's dumbed-down version of Open-SSH.

rsync could, of course, be used instead to do the gets and puts.

jpgMv -- rename photos to date and time

jpgMv uses jpgDate to rename a collection of jpg files so they have names like 2005-10-13_00.jpg or 2005-10-13+15-15-46_00.jpg. jpgMv is particularly useful when merging many photos into one directory; it does not overwrite existing files. jpgDate uses exiftool to get the date and time from the JPEGs.

This job can be done nowadays by using exiftool directly. However, jpgMv predates exiftool; jpgDate used to use another method of getting the dates.

toZen -- build playlists on Creative Zen mp3 players

I used to love these mp3 players! However, my latest (Style M100) is a huge disappointment. Here is a review.

There are two versions of toZen: one for the newer Zen Style M100 and one for the older Zen Style 100 Both take a directory of MP3s and turn it into a playlist on a mounted Creative Zen mp3 player. They might work unchanged on other mp3 players.

toVibe -- put MP3s onto Philips GoGear Vibe mp3 players

toVibe takes a directory of MP3s and puts it onto a mounted Philips GoGear Vibe mp3 player. It might work unchanged on other mp3 players.

These days, I simply keep a copy of the Vibe's Music directory and use rsync to keep the two synchronised.
