Force unmount occupied partition
Alternative if "Lazy unmount" (umount -l) doesn't obey. Alternative for NFS: $ umount -f /media/sdb1 Use with caution: forcing to unmount a busy partition can cause data loss!

create a simple version of ls with extended output
create a short alias for 'ls' with multi-column (-C), file type syntax additions (slashes after directories, @ for symlinks, etc... (-F), long format (-l), including hidden directories (all ./, ../, .svn, etc) (-a), show file-system blocks actually in use (-s), human readable file sizes (-h)

Show a git log with offsets relative to HEAD
Print a git log (in reverse order) giving a reference relative to HEAD. HEAD (the current revision) can also be referred to as HEAD~0 The previous revision is HEAD~1 then HEAD~2 etc. . Add line numbers to the git output, starting at zero: $ ... | nl -v0 | ... . Insert the string 'HEAD~' before the number using sed: $ ... | sed 's/^ \+/&HEAD~/' . Thanks to bartonski for the idea :-)

copy from host1 to host2, through your host
This is a 'nocd' alternative :)
