Hi,

"hidden file" on Unix can be those file with a dot "." as first character as name.

But if u want to secure the content of a file u can use, in editing and creation phase, option "-x" in vi.
So a password will be prompted .

hth

You can also use read/write permission to keep you file for your eyes only.

Unless the files have to go in a specific directory you could put them in a directory the users have no access to.

Hi Yajuvendra ,

In unix hidden files are starts with a period (.) , Any file or directory started with . is a hidden and normal ls -l command will not show this.

To see the hidden file you have to use
# ls -la

Though , if u hide its not protected as it can be visiable by ls -la.

Hence you need to workout with permission . Put the files in a directory and set the permission of that directory . You may also use acl for that. Or write a script to monitor.

Cheers,

Raj

Setting permissions to files is the only way to really secure your data. Just hidding files is not a good practice to security.

You can also use gpg to encrypt your files.

Edit your profile and set the umask to 077:

umask 077

Change the permissions to your files using:

chmod 600 filename

Change the permissions to your directories using:

chmod 700 directory

This permissions will set permissions to files and directories to allow access only to you.
