@DTLow: thanks for the script!
I tried to run it from Script Editor and Evernote gets activated, then the script quits with "The operation couldn’t be completed. No such file or directory".
Yes, I did change the path to exactly what Terminal / pwd displays:
set fileBackupenex to "/Users/markus/Desktop/@Evernote/Evernote_Backup/Notebook-" & notebookName & ".enex"
Markuss-MacBook-Pro:Desktop markus$ pwd
I also have gzip:
Markuss-MacBook-Pro:bin markus$ /usr/bin/gzip
gzip: standard output is a terminal -- ignoring
Any hints what to check for?
