I am using since some years a selvmade tool called tdtmpdir [michelle.konzack@tp570:~] tdtmpdir --show-tmpdirs You have following TMPDIR's cached: FQDN | DIS | TMPDIR ---------------------------------+-----+-------------------------------------- | | /tmp/michelle.konzack.LbUVct aspire1350.private.tamay-dogan.n | | /tmp/michelle.konzack.XC3917 mail.private.tamay-dogan.net | | /tmp/michelle.konzack.YG3771 samba3.private.tamay-dogan.net | | /tmp/michelle.konzack.iV5846 tp570.private.tamay-dogan.net | | /tmp/michelle.konzack.rATqyA tp570.private.tamay-dogan.net | :0 | /tmp/michelle.konzack.rATqyA tp570.private.tamay-dogan.net | :1 | /tmp/michelle.konzack.rATqyA The TMPDIRS are cache with: [michelle.konzack@tp570:~] ls .tmpdir* -rw-r--r-- 1 michelle.konzack private 29 2007-11-01 22:00 .tmpdir_aspire1350.private.tamay-dogan.net -rw-r--r-- 1 michelle.konzack private 29 2007-11-13 14:16 .tmpdir_mail.private.tamay-dogan.net -rw-r--r-- 1 michelle.konzack private 29 2008-08-20 19:43 .tmpdir_samba3.private.tamay-dogan.net -rw-r--r-- 1 michelle.konzack private 29 2008-08-19 23:19 .tmpdir_tp570.private.tamay-dogan.net -rw-r--r-- 1 michelle.konzack private 29 2008-08-20 19:43 .tmpdir_tp570.private.tamay-dogan.net:0 -rw-r--r-- 1 michelle.konzack private 29 2007-12-29 22:04 .tmpdir_tp570.private.tamay-dogan.net:1 The FQDN is, because I am mounting /home/ over NFS and in the /etc/profile I have if [ -x /bin/tdtmpdir ] ; then . /bin/tdtmpdir fi and since not all programs are honoring $TMPDIR I have [michelle.konzack@tp570:~] env |grep /tmp/ TMPDIR=/tmp/michelle.konzack.iV5846 TEMP=/tmp/michelle.konzack.iV5846 TEMPDIR=/tmp/michelle.konzack.iV5846 TMP=/tmp/michelle.konzack.iV5846 Unfortunately GIMP and OpenOffice ignore $TMPDIR and the other three which is realy annoying. Some times ago I have already reported a BUG against GIMP but it was closed.
