Remove the newline after shell command


I have here the code: 

#/bin/sh

cd ~/Desktop/tmp
date "+%m%d%y_%H%M%S_" | xargs -0 mkdir;

This will create a directory with the current date.
The problem here is that the date command will return a date with a newline character at the end.
After mkdir, the folder created will include a newline.
Anybody know how to go about this? I need a folder name without the newline character.
Thanks.

The reason that the newline was included, is that you used the -0 option, which makes xargs use null byte (ASCII 000) as a word boundary. Newlines are then included as part of the words. Dropping -0 makes xargs use whitespace (including newline) as boundary, thus chopping it off.

However, use ghostdog74's solution, it's simpler.

why do you need to pass it to xargs? Don't do the unnecessary

mkdir $(date "+%m%d%y_%H%M%S_")
