setting the password for directory

Dear all,

I am working on debian operating system.My requirement is to set a password
for particular directory.

This directory might be opened in GUI or using cd command.
Is it possible to set a password for directory?

Whenever I opened the directory it needs to ask the password.It should say error unless the password is right.

Please help me........

No. there is no way to sat password for directory. You can chmod permissions, or use encryption:

Try access control lists instead as there isnt really a ready made password manager for folders

It doesn't mean Linux is not capable of encrypting or pad-locking the files, it is equally capable of doing that, only, Linux views passwording a file as NOT NECESSARY anymore because the owner of the file has absolute power to SET PERMISSION CONTROL IN EVERY FILE.

a) To have a file ONLY accessible by the owner (you) do this:

user@host--$: chmod 0700 /folder/file-name

b) If you want a group of chosen users to have access to the file you need to do it in two (2) steps, to wit:

Step 1 - Create a group of users. Do this using your GUI Users/Group applet. Then, in the same applet make the privileged/chosen users to become members of that group (you may need root password to change the /etc/passwd file;
Step 2 - Set the file or folder permission to be accessible only by that group. Use one of those user(s) account when you create the folder or file, then set the folder permissions, in terminal do this:

user@host--$ chmod -R 0750 /folder_name

This will set also all files and sub-directories within it to similar permissions. The privileged member users to the same group of the one who created it will access the file without need of password.

If you need something more than this you can use secure socket layer or gnu's gpg, you may learn about it by reading here, and here, or you can download a third party encryptor click here.

Hope this helps.

Good luck.
