Okay, I love the Finder's new "Create Archive" command\nwhere I can make entire folder trees into a single zip file\nand make them available on the web without hardly any effort.\n\nBut I want to do the same thing from the command line and\neven though I can probably claim to be an expert in the shell\nhaving used it every day for 20 years,\n/usr/bin/zip was not available previously in Solaris and\nthus I've not used it in OSX 10.4.2 and it is giving\nunexpected results.\n\nI have a folder of shell scripts in my current directory\nentitled "daily.backup-3.1". I then use the following command\nto zip it.\n\nzip -r daily.backup-3.1 daily.backup-3.1\n\nWhy do I then get:\n\nzip warning: missing end signature-\-probably not a zip file (did you\nzip warning: remember to use binary mode when you transferred it?)\n\nzip error: Zip file structure invalid (daily.backup-3.1)\n\nSo I then rename the folder to just "daily" to remove all\nthe punctuation in the folder name and, guess what?\nIt works without complaint.\n\nWhy is this? Shouldn't /usr/bin/zip be able to handle\na little standard punctuation???\n\nThanks for any wisdom.
