解决 ubuntu -bash: cannot create temp file for here-document: No space left on device

The first time I used Ubantu, I encountered this annoying error (-bash: cannot create temp file for here-document: No space left on device). Since I am familiar with centos, I can basically understand the error. This error is Say our /tmp space is full, you can use the df -h command to view

root@xxxxxx:~# df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            2.0G   12K  2.0G   1% /dev

/dev/vda1        20G   15G  4.5G  76% /

Since this directory is full, we can either delete some of the useless ones, and that's it. big

Of course, we can also create the tmp directory ourselves, so that this full directory can be replaced,

root@xxxxxx:~# mkdir /big/tmp -p 

root@xxxxxx:~# export TMPDIR=/big/tmp

Next, when we execute the command again, we will find that we are refreshed and no similar errors will occur again.
