Hi Rambo,
I have compiled a collection of commands for such a scenario and I use them quite effectively. Hope it helps you too.
Some simple commands which might be very useful in case of filesystem full. I am giving them below,
1) Find files which are above a particular size in a specific filesystem:
# find / -size +100000c -xdev -print
a)The "+" symbol is important as it enables to list files which are "equal
to" or "above" the size given.
b) The "c" denotes the size in bytes. If not given, it will be taken as
blocks.
c)The "-xdev" option prevents the command going over to other filesystems
other than the one mentioned.
2) To find any files which are in /dev directory that are not special files:
# find /dev -type f -print
1) This command will show any files accidentally created in the /dev
directory by wrong commands (especially during backups).
3) To remove files from /tmp directory which have not been updated for the past
14 days:
# find /tmp -type f -atime +14 -exec rm {} \;
1) If you want to list the files before removing substitute "ll" for
"rm".
2) Similarly, you can check in /var/tmp by substituting the directory name.
4) To remove the files and empty directories which were not accessed for the
past 14 days under /tmp:
# find /tmp -type f -atime +14 -print -exec rm -f {} \;
# find /tmp -type f -atime +14 -print -exec rmdir {} \;
1) This is a 2 line command. The first line will remove
files not accessed for the past 14 days.
2) Second line removes the empty directories. remember to use only "rmdir"
and NOT "rm -r" as "rmdir" will not remove directories which are not empty.
5) To sort the files according to their file size,in descending order:
#!/bin/sh
# Long listing sorted
/bin/ll -aF $* | sort -nr -k 5 | more
a) The above 3 lines should be put inside a file and make it executable.
b) then you can use it as follows, (supposing you having put the above
script in a file named sort_list)
# sort_list /var
This will list files from /var in descending file size order.
Let me know if you require any clarifications.
With Regards,
Mohan.
