Every link to this on the web is dead.

Does anyone have a copy they could mail me? Please?

I could trade it for something or whatever.

It's excellent to not have to remember all the chmod values.. since I don't set things very often, this is golden.

I spoke to soon with my last review. I asked for reverse function in which you could enter the chmod values and the appropriate boxes would be checked, and the developer responded with this version in less than twelve hours! Outstanding! This is a great app that "fills a necessary hole" on OS X. Thanks!

The quote from Dominique PERETTI is incorrect. The correct values go like this:
Read: 4
Write: 2
Execute: 1

Re: this incorrect comment " All you have to remember is the 4-3-1 rule"

It's not 4/3/1, it's 4/2/1. These values arise from the binary value series: 1,2,4,8,16,32, and bit-level math.

Therefore, the values of each permission will range numerically from 0-7. This value is generated by adding together the desired permissions, where each permission type has one of the following values:

read = r = 4
write = w = 2
execute = x = 1

e.g. rwxrw-r-- = 764
r-xr-xr-x = 555
rw-r--r-- = 644

You can read a tutorial I wrote that covers the basics of permissions via the command line here:

All you have to remember is the 4-3-1 rule :

Read : 4
Write: 3
Execute : 1

Read+Write -> 7
Read+Execute -> 5

Um, what? read = 4, write = 2, execute = 1. rw is 6, not 7.

Great work so far! Any change we could get a reverse function as well? IOW, enter the chmod number first and then the necessary boxes are checked.

Will, you really don't need to remember the code rule when you're using chmod command. Instead you can use 'u'ser, 'g'roup, 'o'thers and 'a'll, with plus '+'/minus '-' and 'r'ead, 'w'rite, e'x'ecutable flags to indicate each bit. For example, 'g+r' means it can be read by group; 'o-w' means it can not be written by other users. It's much easier to use, and it's based on the current status: you don't need to 'ls -la' first to acquire the current state first. You will need chmod code only when coding.
