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

Every rm'ed a file you needed? Of course you haven't. But I have. I got sick of it so I created a bash function. Here it is. It'll put trashed files into a $HOME/.Trash/"date" folder according to the date. I have rm aliased to it as well in my bashrc so that I still use the rm command. It'll choke if you attempt to trash a directory if that directory name is already in the Trash. This rarely happens in my case but it's easy enough to add another test and to mv the old dir if necessary.

function trash(){

if [ -z "$*" ] ; then

echo "Usage: trash filename"


DATE=$( date +%F )

[ -d "${HOME}/.Trash/${DATE}" ] || mkdir -p ${HOME}/.Trash/${DATE}

for FILE in $@ ; do

mv "${FILE}" "${HOME}/.Trash/${DATE}"

echo "${FILE} trashed!"




Know a better way?

If you can do better, submit your command here.

What others think

This is my version of the trash command. I accidently rm'ed files one or twice in my life which cause a lot of extra work.

Movin the files to a trash folder in your home directory is nice, but the folder keeps growing if you don't delete the files manually.

I mv the files to /tmp/trash because the /tmp folder is cleaned after the next reboot (my machine runs for weeks).

# Don't remove files immediately. Move them to /tmp/trash instead. They will

# be kept until the next reboot.

# hhanff

function del () {

if [[ -z "$*" ]] ; then

echo "Usage: del FILE_NAME "


# Test if /tmp/trash exists and proceed with deleting files if it

# exists. If it does not exist, e.g. after a restart, create the

# directory and proceed.

if [ -d /tmp/trash ]


echo "/tmp/trash exists. Proceeding." > /dev/null


mkdir /tmp/trash


# TBD: Do not move every file separately, but

# mv all files at once... don't know how...

while [ $# -ne 0 ]


# Files will be prescedet with a timestamp.

# basetime=$(date "+%FT%T")

# basetime=$(date +%s%N)

basetime=$(date "+%Y%m%dT%H%M%S")

#echo $1

# Make whitespaces underscores

TRIMMED_1=`echo "$1" | sed 's/ /_/g'`

TRIMMED_2=$(basename $TRIMMED_1)

# Move files to /tmp/trash

mv "$1" /tmp/trash/"$basetime"-"$TRIMMED_2";
