−Make label on FAT32 volume.
+
−===========================
+
−
+
−The volume name can be up to 11 characters long::
+
−
+
−  $ sudo mlabel -i /dev/<device> ::my-label
+
−
+
−or when create FAT32 file system::
+
−
+
−  $ sudo mkdosfs -n <vol-name> /dev/<device>
+
−
+
−Convert file name coding.

−  $ convmv --nosmart -f cp-1251 -t utf-8 -r $dir

+
−How get file time attributes.
+
−=============================
+
−
+
−POSIX define 3 file time attributes: atime (access time, only a few OS/fs update
+
−this parameter), ctime (attribute/inode modification time), mtime (modification
+
−time).
+
−
+
−To get time you can use 'ls' command but it print time in locale dependent
+
−irregular form::
+
−
+
−  $ ls -l file.txt      # last file modification
+
−  $ ls -lc file.txt     # last file status modification
+
−  $ ls -lu file.txt     # last access
+
−
+
−GNU coreutils provide more robust 'stst' utility::
+
−
+
−  $ stat -c %Y file.txt # last file modification
+
−  $ stat -c %Z file.txt # last file status modification
+
−  $ stat -c %X file.txt # last access

−  lrwxrwxrwx 1 root root 10 2010-11-01 23:41 46B6-1FD4 -> ../../sdb2

−How set UUID and label?
+
−=======================
+
−
+
−For ext2/ext3 fs::
+
−
+
−  $ sudo tune2fs /dev/hdb1 -U `uuid`
+
−
+
−Linux fs under Windows.
+
−=======================
+

+
−Ext2 IFS.
+
−---------
+
−
+
−It provides Windows NT4.0/2000/XP/2003/Vista/2008 with full access to Linux Ext2
+
−volumes (read access and write access). This may be useful if you have installed
+
−both Windows and Linux as a dual boot environment on your computer.
+
−
+
−The "Ext2 Installable File System for Windows" software is freeware.
+
−
+
−After install use 'ifsdrives.cpl' control panel to modify settings.

+
−Allows you to access ReiserFS partitions from a Windows 95/98/ME/NT/2000/XP
+
−system. It also allows you to access ReiserFS partitions from Linux. It is a
+
−complete rewrite of the ReiserFS functions needed to list directories, copy
+
−files, and backup metadata.

−Mount NTFS in Linux.
+
−====================
+
−
+
−Mount in rw mode::

−Stop fsck running every 27 boots.
+
−=================================
+
−
+
−Check current settings::
+
−
+
−  $ tune2fs -l /dev/$DISK
+
−
+
−and tune them::
+
−
+
−  $ tune2fs -c 0 /dev/$DISK
+
−  $ tune2fs -i 2w /dev/$DISK
+
−
+
−Or disable checks in ``/etc/fstab`` completely (by setting last colon to ``0``
+
−value)!
