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.

Always _quote_ the variables!

from AlvinaSimpson over on 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" ] to [ -e "$1" -a -d "$2" ] and from mv "$1" "$2" to 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.

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)

I like it very much, and I am looking forward to Hearing from your next. I recommend you to visit my site on Touch Typing Practice for wpm test online. One of the new methods of typing that has become ground in recent times is touch typing. This is a faster and more efficient way of typing and is better than the traditional ‘hunt and peck method. You can also check your touch typing speed with the wpm test tool free of cost online. Click here :

Dropbox is awesome. It makes file syncing (and sharing) easier and more reliable. But sometimes, you may want to sync a local directory to your Dropbox for some reasons (privacy, security. To check this and get more things about gaming. Normally it's not possible, you can only sync files/directories in your Dropbox folder to your computer... until Dropbox enabled
