Commands using du

Useful for analyzing disk usage. If you prefer GUI try http://en.wikipedia.org/wiki/Filelight or http://www.marzocca.net/linux/baobab/

When you've got a list of numbers each on its row, the ECHO command puts them on a simple line, separated by space. You can then substitute the spaces with an operator. Finally, pipe it to the BC program.

Built-in function in linux, should work on any distro

Found this one little more for me. This one removes the perl dependency (from command 2535).

Source for command : http://www.earthinfo.org/linux-disk-usage-sorted-by-size-and-human-readable/

using mb it's still readable;) a symbol variation

$ du -ms {,.[^.]}* | sort -nk1

Taken from http://www.earthinfo.org/linux-disk-usage-sorted-by-size-and-human-readable/

somewhat faster version to see the size of our directories. Size will be in Kilo Bytes. to view smallest first change '-k1nr' to '-k1n'.

Here the pattern is '*.jar', you could pass in any pattern.

Another, maybe nicer way to do this is

http://www.commandlinefu.com/commands/view/1921/summarise-the-size-of-all-files-matching-a-simple-regex

You could replace sed with tr

Use the find command to match certain files and summarise their total size in KBytes.

This command will tell you the 20 biggest directories starting from your working directory and skips directories on other filesystems. Useful for resolving disk space issues.

Finds all directories containing more than 99MB of files, and prints them in human readable format. The directories sizes do not include their subdirectories, so it is very useful for finding any single directory with a lot of large files.

Sometimes you want to know the summary of the sizes of directories without seeing the details in their subdirectories. Especially if it is going to just scroll off the screen. This one liner summarizes the disk usage of any number of directories in a directory without giving all the details of whats happening underneath.

You also can sum the file usage of all files

This example summarize size of all pdf files in /tmp directory and its subdirectories (in bytes).

Replace "/tmp" with directory path of your choice and "\*pdf" or even "-iname \*pdf" with your own pattern to match specific type of files. You can replace also parameter for du to count kilo or megabytes, but because of du rounding the sum will not be correct (especially with lot of small files and megabytes counting).

In some cases you could probably use sth like this:

But be aware that this second command CANNOT count files with spaces in their names and it will cheat you, if there are some files matching the pattern that you don't have rights to read. The first oneliner is resistant to such problems (it will not count sizes of files which you cant read but will give you correct sum of rest of them).

The pipe to head removes the listing of . as the largest directory.

Very useful when you need disk space. It calculates the disk usage of all files and dirs (descending them) located at the current directory (including hidden ones). Then sort puts them in order.

I use this on debian testing, works like the other sorted du variants, but i like small numbers and suffixes :)
