  • If you are an unlucky soul behind a corporate firewall you will likely find that downloading gpg keys is blocked. This is because the hkp protocol uses port 11371 by default to transfer the key. By adding "hkp://" to the beginning of the hostname and ":80" to the end you are asking gpg to try using port 80 to connect (less likely to be blocked by a firewall). This relies on the remote server answering to requests over port 80. Show Sample Output

    sudo apt-key adv --keyserver hkp:// --recv-keys [key to get here]

  • Runs the identify command (from ImageMagick) on each jpg file in the current directory and returns image details according to the format parameter. The example here returns: Filename FileSize Compression Width Height More information about the available format options can be found here: I usually redirect the output to a text file using "> listofdetails.txt" at the end. Spreadsheet magic can then be applied. Show Sample Output

    for file in *.jpg; do identify -format '%f %b %Q %w %h' $file; done
