Subject: Some useful permission setting scripts


I've tried a bunch of things, nothing seems to work better and more
cleanly than these few scripts I wrote for setting or resetting file
permissions in cygwin on Windows XP, especially when things seem
"stuck" or "weird".  The order of the chmod and the chown before the
cacls command is important.  The double quotes are important,
especially since there are MANY spaces in filenames in Windows.

----------------------------------------
FILENAME: /usr/local/bin/permission-everyone
PURPOSE:  Resets permission recursively to be available to everybody
USAGE:    It takes a while for this to complete if your directory
          is big, just wait.
----------------------------------------
#! /bin/sh

for file in "$@"; do
    echo "$file"
    chmod -R 777 "$file"
    chown -R Administrators:SYSTEM "$file"
    echo "y" | cacls "$file" /t /g "everyone:f"
done


----------------------------------------
FILENAME: /usr/local/bin/permission-bozo
PURPOSE:  Lets me and
WARNING:  If you omit "nt authority\system" then services that start
          at system time can't read your files.
WARNING:  If you omit "administrators" then if you reinstall Windows,
          you can NEVER, NEVER, EVER get to the file again, even as
          administrator!  (SOLUTION: use partition magic, convert
          your drive to "FAT32" drops the bad permission, then
          convert your drive back to "NTFS" which sets default
          permissions letting you get to your files again).
NOTE:     Replace bozo with your user name.
----------------------------------------
#! /bin/sh

for file in "$@"; do
    echo "$file"
    chmod -R 755 "$file"
    chown -R Administrators:SYSTEM "$file"
    echo "y" | cacls "$file" /t /g "nt authority\system:f" "bozo:f" "administrators:f"
done


----------------------------------------
FILENAME: /usr/local/bin/permission-bozo-not-recursive
PURPOSE:  Same as above, but only works on the one file, not recursively
----------------------------------------
#! /bin/sh

for file in "$@"; do
    echo "$file"
    chmod 755 "$file"
    chown Administrators:SYSTEM "$file"
    echo "y" | cacls "$file" /g "nt authority\system:f" "bozo:f" "administrators:f"
done


----------------------------------------
FILENAME: /usr/local/bin/permission-strictly-bozo
PURPOSE:  If you ignore the warnings above, use this to make the
          files only viewable strictly by bozo.
WARNING:  See warning above about not letting Administrator in.
          You've been warned!
NOTE:     Replace bozo with your user name.
----------------------------------------
#! /bin/sh

for file in "$@"; do
    echo "$file"
    chmod -R 700 "$file"
    chown -R Bozo:None "$file"
    echo "y" | cacls "$file" /t /g "bozo:f"
done
