This command is useful for finding out which directories below the current location use the most space. It is summarised by directory and excludes mounted filesystems. Finally it is sorted by size.
I wanted an easy way to list out the sizes of directories and all of the contents of those directories recursively.
I don't like doing a massive sort on all the directory names just to get a small set of them. the above shows a sorted list of all directories over 1GB. use head as well if you want.
du's "-x" flag limits this to one file system. That's mostly useful when you run it on "/" but don't want "/proc" and "/dev" and so forth. Remember though that it will also exclude "/home" or "/var" if those are separate partitions.
the "-a" option is often useful too, for listing large files as well as large directories. Might be slower.
list the top 15 folders by decreasing size in MB
h means human readable ,
Enhanced version: fixes sorting by human readable numbers, and filters out non MB or GB entries that have a G or an M in their name.
Show sizes of all files and directories in a directory in size order.
du -hs * | sort -hr
for reverse order.
You can simply run "largest", and list the top 10 files/directories in ./, or you can pass two parameters, the first being the directory, the 2nd being the limit of files to display.
Best off putting this in your bashrc or bash_profile file
Lists the size in human readable form and lists the top 25 biggest directories/files
Also shows files as they are found. Only works from a tty.
