Change temporary directory in Linux

Sometimes, the size of / (root) mount is limited and in result some processes requiring large /tmp may fail. This can be solved by setting environmental variable TMPDIR:
[bash]
mkdir -p /home/$USER/tmp
TMPDIR=$(mktemp -d /home/$USER/tmp/XXXX)
TMP=$TMPDIR
TEMP=$TMPDIR
export TMPDIR TMP TEMP
[/bash]
