Show HN: File Permissions Ninja

[AnkhMorporkian]

I love it, but it would be nice if it didn't break the back button every time you click on a checkbox.

[arnel]

It's the permalink.

Every time you click on a checkbox the permalink is change according to the permission, so its easier to copy the permalink. Therefore when you click the back button you're going to the previous state.

Do you think its not a good behavior?

[piqufoh]

Looks good, have been wanting something like this for a while. Bookmarked!

Also, love the use of .ninja domain - definitely most appropriate usage I've seen to date!

[arnel]

I didn't bookmarked it ;)

I didn't because i wrote a small command line utility to open the site with the right parameters.

You can also use it (instructions for ubuntu):

Copy the folowing to file with the name per:

#!/bin/bash

NC='\e[0m' # No Color

green='\e[0;32m'

blue='\e[0;34m'

if [ "$#" == "0" ]; then

echo "Usage: $0 filename" exit 1 fi

if [ "$#" != "1" ]; then

red='\e[0;31m'

echo -e "${red}$# Is illegal number of parameters.${NC}" exit 1 fi

usage(){

echo -e '\tper'

echo -e '\tOpen http://file-permissions.ninja with permission of the file.'

exit 1

}

if [ "$1" == "help" ] || [ "$1" == "-help" ] || [ "$1" == "-h" ] ; then

usage

fi

mode="`LC_ALL=C LANG=C /bin/ls -ld "$1" | LC_ALL=C LANG=C awk '{ print $1 }'`" || exit $?

echo -e "${blue}Opening: ${green}http://file-permissions.ninja/#$mode${NC}"

xdg-open 'http://file-permissions.ninja/#'$mode &> /dev/null

exit 0

# EOF ----------------------------------

Move per to folder within the path.

Let's say:

sudo mv per /bin

Now grant it execute permission:

sudo chmod +x /bin/per

Now you can use it with:

per filename

it's supposed to open the site with the permissions of filename.

Neat. I suggest adding an explanation of what the special bits do (tooltip type of help on clicking the link?), as this is what's not obvious for most people.

[ajanuary]

It needs to add numpad keys to it's whitelist. Currently I can't use the numpad in the input boxes.

[claar]

Yeah, same problem here. At first I thought he had skipped out on allowing you to type the mask, which is the killer feature of a utility like this.

Also, when typing into the binary input, it isn't updating immediately on key-up like the rest of the inputs -- I'm having to hit the arrow keys to get it to update.

Nice utility, though!

[dkopi]

This is pretty cool and well done, but I kind of wish there was no need for this to exist. It seems that as the world progresses to higher level language, bit manipulations and binary calculation are the realm of dinosaurs.

[DevUps]

This is great, thanks! I suggest putting a check all box at the top of each column. That's my 2 cents.

[diaz]

Great, I'll try to remember this to use it.

Now add an advanced mode for easy configuring setfacl :P

[rikkus]

Looks lovely.

Have you thought about the ugoa/rwx... etc. version of the flags, i.e. partial setting?

[arnel]

Yep :)

Working on it...

[GigabyteCoin]

I actually stumbled across this on Google just yesterday and found it quite useful.

[Phogo]

Easy to understand, really like the help walkthough style too. Nice job.

[arnel]

Thanks. The walkthrough is made with intro.js

Can be found here: https://github.com/usablica/intro.js

[Erwin]

Now please add a full interactive explanation of Posix ACLs.

[phloxicon]

Very handy. Thanks.

[probinso]

doesn't work with number pad

[arnel]

it was a small bug but i fixed it.

Now it should work with the number pad.

To make it work load it without cache: ctrl+shift+R

Thanks for the comment!
