Warning!, if the pattern didn't find anything it shows the total size of dot dir

Thanks for the submit! My alternative produces summaries only for directories. The original post additionally lists all files in the current directory. Sometimes the files, they just clutter up the output. Once the big directory is located, *then* worry about which file(s) are consuming so much space.

sorts the files by integer megabytes, which should be enough to (interactively) find the space wasters. Now you can

for the above output,

for only the 3 biggest files and so on. It's always a good idea to have this line in your .profile or .bashrc

This is easy to type if you are looking for a few (hundred) "missing" megabytes (and don't mind the occasional K slipping in)...

A variation without false positives and also finding gigabytes (but - depending on your keyboard setup - more painful to type):

(NOTE: you might want to replace the ',' according to your locale!)

Don't forget that you can

modify the globbing as needed! (e.g. '.[^\.]* *' to include hidden files and directories (w/ bash))

in its core similar to:

If a directory name contains space xargs will do the wrong thing. Parallel https://savannah.nongnu.org/projects/parallel/ deals better with that.

What happens here is we tell tar to create "-c" an archive of all files in current dir "." (recursively) and output the data to stdout "-f -". Next we specify the size "-s" to pv of all files in current dir. The "du -sb . | awk ?{print $1}?" returns number of bytes in current dir, and it gets fed as "-s" parameter to pv. Next we gzip the whole content and output the result to out.tgz file. This way "pv" knows how much data is still left to be processed and shows us that it will take yet another 4 mins 49 secs to finish.

A little bit smaller, faster and should handle files with special characters in the name.

Based on the MrMerry one, just add some visuals to differentiate files and directories

An NCurses version of the famous old 'du' unix command

the f is for file and - stdout, This way little shorter.

I Like copy-directory function It does the job but looks like SH**, and this doesn't understand folders with whitespaces and can only handle full path, but otherwise fine,

function copy-directory () { ; FrDir="$(echo $1 | sed 's:/: :g' | awk '/ / {print $NF}')" ; SiZe="$(du -sb $1 | awk '{print $1}')" ; (cd $1 ; cd .. ; tar c $FrDir/ )|pv -s $SiZe|(cd $2 ; tar x ) ; }

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

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

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

Oracle DBA remove some logfiles which are still open by the database and he is complaining the space has not been reclaimed? Use the above command to find out what PID needs to be stopped. Or alternatively recover the file via:

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

find largest file in /var

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.

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).
