Unfortunately, for a number of reasons, I’ve been far too busy to follow up my previous\u00c2\u00a0post<\/a>\u00c2\u00a0to use Mac OS X’s launchd to detect when the Sony eReader connects. There’s a lot of good launchd stuff on the Web, though, and it promises to be pretty easy once I sit down and actually write a plist for it.<\/p>\n

In the mean time, here’s a revised script for moving the printed PDF files from a spooling directory to the eReader on connection. The setup is the same as before<\/a>; simply kick the script with a Folder Action.<\/p>\n

#!\/usr\/bin\/env sh\r\nPATH=\/opt\/local\/bin:\/usr\/bin:\/bin:\/usr\/sbin:\/sbin:\/usr\/local\/bin\r\nexport PATH\r\n\r\nreadermain=\"\/Volumes\/PRS 700\"\r\nreadercard=\"\/Volumes\/700 CARD\"\r\nspool=\"\/Users\/kf6gpe\/.cups-pdf-spool\"\r\npdfdest=\"$readercard\/PDFs\/\"\r\n\r\ngrowl()\r\n{\r\n    message=\"$*\"\r\n    which growlnotify > \/dev\/null\r\n    if [ $? -eq 0 ]; then\r\n        echo $message | growlnotify -t \"eReader\" -p -2 -a \/Applications\/Preview.app\r\n    fi\r\n}\r\n\r\nif [ -f \"\/tmp\/prs-busy\" ]; then\r\n    exit 0;\r\nfi\r\n\r\nif [ -d \"$readercard\" ]; then\r\n    touch \/tmp\/prs-busy\r\n    growl \"Device detetected.\";\r\n    for f in `ls $spool\/*.pdf`\r\n    do\r\n        cp $f \"$pdfdest\"\r\n        if [ $? -eq 0 ]; then\r\n            rm -f $f\r\n            growl \"Transferred `basename $f`.\"\r\n        fi\r\n    done\r\n    growl \"PDF transfer complete.\";\r\n    rm \/tmp\/prs-busy\r\nelse\r\n    rm \/tmp\/pre-busy 2>&1 \/dev\/null\r\nfi<\/pre>\n
exit 0<\/pre>\n
The changes are pretty self-explanatory. In brief:<\/p>\n
    \n
  1. Have use Preview’s icon, in case Calibre isn’t installed.<\/li>\n
  2. Only look for the eReader’s card; there’s really no reason to look for both volumes.\u00c2\u00a0<\/li>\n
  3. Use the lock file \/tmp\/prs-busy<\/tt> to ensure that the actual movement of the files doesn’t occur while it’s actually running.\u00c2\u00a0<\/li>\n<\/ol>\n
    Of these changes, (3) was certainly the most important, because if you mounted another volume (say, a digital camera) while the script was doing things, weird things could happen. In practice, I never saw anything amiss, but this makes me sleep better at night.<\/p>\n","protected":false},"excerpt":{"rendered":"
