Remove all the unwanted files & dir in /tmp.it will reduce ..If u want that files take a backup using fbackup & delete it.

hi

can do a

#du -k /tmp | sort +n | pg

have a look as per the file size and see if some of the files can be moved.
100 % full /tmp shall make the system un-bootable.

Hi:

Re: "...100 % full /tmp shall make the system un-bootable...", could the poster of this comment be a little more careful with his / her adivce giving. This is such an obvious mistake I won't even comment on it.

du -k /tmp | sort -rn | more (* is good for finding biggest to littlest file sizes *)

ls -lart (* is good for get a chronological listing oldest to newest *)

lsof /tmp (* is good for find running processes still writing to open files within the /tmp filesystem *)

cd /tmp
touch /tmp/file_mfs
find /tmp -type f -newer /tmp/file_mfs -exec ll {} \; (* is good for finding runnaway processes, or, hard to find children of killed parents still writing to a file system *)

100% full /tmp does not make the system unbootable. It just causes some badly designed and authored software to malfunction or not work at all.

you can sort /tmp by date

cd /tmp
ls -lt | tail -50 > /var/tmp/oldtempfiles

take say the oldest 50 files at the bottom

for f in $(cat /var/tmp/oldtempfiles)
do
fuser $f | awk {'print $1'} >/var/tmp/tfile.tmp
cat /var/tmp/tfile.tmp|grep -q ^[0-9]
r=${?}
if [ $r -ne 0 ]
then
echo "$f: file not open" # can be deleted
else
echo "$f: file open" # do nothing
fi
done

But as always, use common sense before deleting people's files. They may get upset. Last thing you want to do, upset the assistant of the big boss.

Then perhaps unusable. There have been threads where a full / has caused the passwd file to be blasted if trying to edit it.
(I suppose this comes under your "badly designed" statement. ;-)

The /tmp 100% does not make system unbootable.

First of all go to
# cd /tmp

check and core file or and log file, which we can immediatily delete or move from the /tmp. If by doing this some size is reduced do

# du -sk *|sort -nr|more

It will sort the file with maximum size, from which you can get the idea, which file (consuming more size) needs to be deleted.

Hope this may help you

Hi,

Try to find core and any large old files that can be move to other lication--

(1) find /tmp - name core*

(2)cd /tmp
du * | sort -rn | head sort the large file with its size in descending order

(3)du -kx /tmp | sort -rn | more ( Listing the large file in kb )

(4)find . -xdev -type f -size + 100000 -exec ls lrt{}\+
