Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

sweet. i've made it a function in all my .bash_profiles.

function lmv(){

[ -e $1 -a -e $2 ] && mv $1 $2 && ln -s $2/$(basename $1) $(dirname $1);

It only works, if $2 is a directory, though.

Also does not play nice with files that have spaces or meta-characters in the names.

Comment by TheMightyBuzzard 392 weeks and 5 days ago

Always _quote_ the variables!

Comment by jxy 392 weeks and 4 days ago

from AlvinaSimpson over on lifehacker.com:

lmv() { [ -e "$1" -a -e "$2" ] && mv "$1" "$2" && ln -s "$2"/"$(basename "$1")" "$(dirname "$1")"; }

Me, I'd add one more bit and say go from

[ -e "$1" -a -e "$2" ]


[ -e "$1" -a -d "$2" ]

and from

mv "$1" "$2"


mv "$1" "$2"/

That should take care of any accidental file overwrites from trying to use wildcards with this command as it requires $2 be a directory and appends a trailing / so we don't accidentally try to overwrite the directory $2

By default, you shouldn't be trying to symlink when you do this; you only need to use symlinks when you're going from one physical drive to another.

The files that we see in the filesystem are pointers to the actual data on the drive. By creating a hard link, we have two real pointers to the same data; if one is removed, the other exists still, and the data is still "found" by the filesystem. If the original hardlink disappears but the symlink still exists, the symlink won't work.

When trying to do a "safe move" using links, hard links is what you should use.

great suggestions for improving the function! i love this place!

Comment by thebillywayne 392 weeks and 3 days ago

Any recommendations to make this usable on directories with spaces or special characters? I want to use it to relocate bittorrent files regularly to another disk and they rarely have proper filenames.

by recommendations I mean a simpler way than writing/stealing code to escape all the special characters. I'm lazy and slow!

lmv(){for a in ${@:1:$(expr $#-1)};do [ -e "$a" -a -e "${@:$#:1}" ] && mv "$a";"${@:$#:1}" && ln -s "${@:$#:1}"/"$(basename "$a")";"$(dirname "$a")";done}

for multiple folders (e.g. lmv files/* newfolder would move file/* to newfolder while symlinking them)
