File system.

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

How get UUID and label?

Include UUID (Universally Unique Identifier) and labels:

$ ls -l /dev/disk/by-uuid/
lrwxrwxrwx 1 root root 10 2010-11-01 23:41 46B6-1FD4 -> ../../sdb2
lrwxrwxrwx 1 root root 10 2010-11-01 23:41 4C30299030298256 -> ../../sda1

$ ls -l /dev/disk/by-label/
lrwxrwxrwx 1 root root 10 2010-11-01 23:41 bin -> ../../sda3
lrwxrwxrwx 1 root root 10 2010-11-01 23:41 inst -> ../../sda2
lrwxrwxrwx 1 root root 10 2010-11-01 23:41 media -> ../../sdc5

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.

Ext2Fsd.

Ext2Fsd is an open source linux ext2/ext3 file system driver for Windows systems (NT/2K/XP/VISTA, X86/AMD64).

rfstool.

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.

Summary files size.

$ find . -type f -iname "*.log" -print0 | du --files0-from=- -c -m | tail -n 1 \
    | (read first rest; echo $first)

Mount NTFS in Linux.

Mount in rw mode:

$ man 8 ntfs-3g
$ cat /etc/fstab
...
UUID=D474CB9874CB7C2C /mnt/winbin ntfs-3g rw,default_permissions,gid=1000,fmask=113,dmask=002,noatime,silent 0 0
...

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)!
