在shell命令之后删除换行符

Question

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.

Answer 1

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

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

Answer 2

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.
