Calculates the size on disk for each package installed on the filesystem (or removed but not purged). This is missing the

| sort -rn

which would put the biggest packges on top. That was purposely left out as the command is slightly on the slow side

Also you may need to run this as root as some files can only be checked by du if you can read them ;)

change the *.avi to whatever you want to match, you can remove it altogether if you want to check all files.

Show time and date when you installed your OS.

sudo find /var/log/ -mtime -7 -type f | xargs du -ch | tail -n1
2009-08-27 14:18:47
User: alvinx
Functions: du find sudo tail xargs

get diskusage of files (in this case logfiles in /var/log) modified during the last n days:

sudo find /var/log/ -mtime -n -type f | xargs du -ch

n -> last modified n*24 hours ago

Numeric arguments can be specified as

+n for greater than n,

-n for less than n,

n for exactly n.

=> so 7*24 hours (about 7 days) is -7

sudo find /var/log/ -mtime -7 -type f | xargs du -ch | tail -n1

to download latest version of "util", maybe insert a sort if they wont be shown in right order.

curl lists all files on mirror, grep your util, tail -1 will gets the one lists on the bottom and get it with wget

The `-q' arg forces tail to not output the name of the current file
