Remove Extended attributes present in file permission in Mac OS

Hi Guys,

For the past two days I was struggling to get rid of the '@' character which is appended in the permission for a file whenever used using the TextMate Editor in the Mac OS. I opened TextMate Editor and created a file called "test.txt" which is created successfully but unfortunately the permissions saved are


-rw-r--r--@ 1 kishorekumar admin 5 Nov 11 13:56 test.txt


Now I felt strange regarding this why this @ came and what is that exactly. Later after two days of digging I found the answer and now I am relaxed. Oops sorry to continue my story.. continuing back..

What I understood regarding the '@' is that it is file extended attributes for the Mac files. You can see them with the -@ flag to ls, or with the new xattr command:


ls -al test.txt
-rw-r--r--@ 1 kishorekumar admin 5 Nov 11 13:56 test.txt



ls -al@ test.txt
-rwxr-xr-x@ 1 kishorekumar admin 11614 Nov 11 12:27 test.txt
com.macromates.caret 35



xattr -l test.txt
com.apple.FinderInfo:
0000 00 00 00 00 54 78 4D 74 00 00 00 00 00 00 00 00 ....TxMt........
0010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................

com.macromates.caret: {
column = 7;
line = 295;
}


So now, how to get rid of the '@' and the com.apple.FinderInfo & com.macromates.caret so here is the simple and fastest solution which works faster.

To Disable the Extra Attributes which gets attached to the file is just run this below command in the Terminal.

defaults write com.macromates.textmate OakDocumentDisableFSMetaData 1


To Enable the Extra Attributes which gets attached to the file is just run this below command in the Terminal.

defaults write com.macromates.textmate OakDocumentDisableFSMetaData 0


Note: Make sure that you restart the TextMate Application else it might not work perfectly.

Hope this might help you easily. If not please let me know I will try to help you :-)

ER Diagram Tool for Mac

Have you ever did an ER Diagram for the Tables ? hmm, I hope yes, you might have did in your schoolings. Did you thought at that time how much it will be useful later ? Ok, Ok, coming straight to the point, I was figuring out any tool which might do the ER Diagram easily without straining too much. Atlast I found one for Mac.

Clear Cache in Mac OS X might increase fast bootup

Last week I went to a service center to ask why my Mac book is slow only while booting. One of the suggestion was that RAM present in the Mac to be increased which might cost little expensive. This was definite but spending money would mean that we need to think really is that needed ? Anyway I also asked him is there any other way without spending money really much. He suggested two ways which help to improve the Mac performance better.

a) To clear the caches

To clear the cache you need to move all the files from /Library/Caches to Trash
Also Move all the files from /Users//Library/Caches to Trash

b) Need to have 60 GB of free space

I have a HDD of 200 GB and 2GB RAM in which 1GB RAM is fully utilized by the Mac Leopard itself. Whenever I have less than 40GB of space, my Mac drive slowly and sometimes i feel its hanged but never.

Hope this might solve you too.

Copy Window Freezed in MacOS Finder

Before Reading please make sure that I have alternative solution only, I don't have proper solution.

I was trying to copy files from remote location to my laptop, after 25% of completion the network connectivity was lost. I was surprised to see that copy window got freezed and even the cancel button (x) was also not working. I kept the window open for 2 days and meanwhile I was working on the other things. Atlast my laptop started working slowly so I thought if I get rid of this frozen window it would make my life easier. Unfortunately there was no PID for this to kill it, so atlast I made a Force Quit of the Finder which automatically restarted the Finder and it was good. But I don't know is there any other good idea to get rid of this.

Please help me out if you have any answers for this as I couldn't find any solution even after googling it out.

Sharing files and folders from Mac OS X to Ubuntu

Sometimes you want a folder from Mac OS X to be shared and need to be accessed by Ubuntu then you need to follow the below link, which is really nice and beautiful. I was in search for not using "scp" / "ssh" command as I have to log in as a user and need to give pwd too.

Please follow Mac OS X File Sharing
