pingstatus.pl — Check for server downtime. |
Wanting to continuously check if a server is losing connectivity, I quickly put togethor a small perl script to do the job.
Open the file and edit the variables to determine debug status, email details, server ip etc.
By default it sends a ping every second. If this test fails 5 times in a row, a report is sent via mail.
Disable debug for it to run silently in the background.

exifsort.pl – Sort digital images by EXIF date. |
I use 2 digital cameras, and my phone, to take pictures nearly every day. I came accross a perl script written by Lars Strand. This copied photos from CAM0001.JPG to a date formatted file such as 20070113.0900.JPG.
I decided to take this as a base, and change it into something that suited my own needs.
The script will take directories on the command-line and copy any pictures found to a target directory set within the script. It then creates a file and directory structure based on the EXIF time/date found in the JPEG.
For example
/source/CAM0001.JPG
now becomes
/target/2007/11.nov/20070113.0900.jpg
making the files easy to find and splitting them into months.
The script produces an output such as,
ExifSort v1.0 - http://www.nooblet.org/exifsort/o Processing folder, /mnt/storage/Photos/100DSCIM/
o Processing folder, /mnt/storage/Photos/100CASIO/

o Processing complete.
12 files copied.
- 101 files the same.
The script checks modified dates and file sizes, and will compare the md5 checksum if it still isn’t sure, to know if it has already copied an existing file.
The photos folder in my family photo gallery is a direct result of this exif sorting script.
