    参考 
很奇怪的事情
cd /m 

之后打了一个tab给我提示：
bash: cannot create temp file for here-document: No space left on device

查了一圈之后找到答案：(具体原因不明，需要以后查看）
Solution:
# do this part one time only
mkdir /path/to/mytmp
chmod 1777 /path/to/mytmp

# put this in .bashrc or your login .profile  file
# it has to execute BEFORE you want TMPDIR to work
export TMPDIR=/path/to/mytmp
