set label on ext2, ext3, XFS, JFS,Reiserfs # tune2fs -L labelName /dev/sdxx
set label on ext2/3 # e2label /dev/sdxx labelName
set label on reiser fs: reiserfstune
set swap label - BEWARE: ALTERS UUID # mkswap -L labelName /dev/sdaX
set dos label (in mtools) # mlabel -i /dev/sdaX ::
set ntfs label (in ntfsprogs) # ntfslabel /dev/sdaX
set swap label # mkswap -L labelName /dev/sdxx
list UUID, label, and more # vol_id /dev/sdaX
list only UUID # vol_id -u /dev/sdaX
list bunches of info # dumpe2fs -h /dev/sda1
list all labels blkid -s LABEL /dev/sda*
list all partitions # fdisk -l
list all device names (I found this more accurate than vol_id):
     ls /dev/disk/by-*
list mount points with labels mount -l
mount/unmount swap # [swapon | swapoff] -a

Thanks to Marty Felker for inspiring this post.
