as per eightmillion's comment. Simply economical :)
1du -h | sort -hr -
This command give a human readable result without messing up the sorting.
1for i in G M K; do du -hx /var/ | grep [0-9]$i | sort -nr -k 1; done | less -
In OSX you would have to make sure that you "sudo -s" your way to happiness since it will give a few "Permission denied" errors before finally spitting out the results. In OSX the directory structure has to start with the "Users" Directory then it will recursively perform the operation. Your Lord and master, Mematron Show Sample Output
1sudo -s du -sm /Users/* | sort -nr | head -n 10 -
You can simply run "largest", and list the top 10 files/directories in ./, or you can pass two parameters, the first being the directory, the 2nd being the limit of files to display. Best off putting this in your bashrc or bash_profile file Show Sample Output
1largest() { dir=${1:-"./"}; count=${2:-"10"}; echo "Getting top $count largest files in $dir"; du -sx "$dir/"* | sort -nk 1 | tail -n $count | cut -f2 | xargs -I file du -shx file; } -
To sort the list by file/directory size, insert `sort -n |` before `awk`. Show Sample Output
1du -Lsbc * |awk 'function hr(bytes){hum[1024**4]="TiB";hum[1024**3]="GiB";hum[1024**2]="MiB";hum[1024]="kiB";for(x=1024**4;x>=1024;x/=1024){if(bytes>=x){return sprintf("%8.3f %s",bytes/x,hum[x]);}}return sprintf("%4d B",bytes);}{print hr($1) "\t" $2}' -
Simple and easy to remember. -h is human, -d1 = depth 1. disk usage, human, depth 1 Show Sample Output
1du -h -d1 -
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:
du -cb `find /tmp -type f -iname \*pdf`|tail -n 1But 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). Show Sample Output0SUM=0; for FILESIZE in `find /tmp -type f -iname \*pdf -exec du -b {} \; 2>/dev/null | cut -f1` ; do (( SUM += $FILESIZE )) ; done ; echo "sum=$SUM" -
0du -sh *
-
Warning!, if the pattern didn't find anything it shows the total size of dot dir Show Sample Output
0find . -name 'pattern'| xargs du -hc -
A really useful pair of du options. Show Sample Output
0du -hs /path/to/target -
print sum of disk usage for filetype within current dir and subdirs Show Sample Output
0find . -name '*.xml' -type f -print | xargs du -ch -
Credit goes to brun65i but he posted it as a comment instead as an alternative. I hadn't noticed the -h option on sort before and this seems like the cleanest alternative. Thanks Brun65i! Show Sample Output
0du -h --max-depth=1 | sort -hr -
Shows the size of the directory the command is ran in. The size is in MB and GB. There is no need to type the path, its the current working directory. Show Sample Output
0du -sh `pwd` -
0du -s $(ls -l | grep '^d' | awk '{print $9}') | sort -nr
-
the -h option of du and sort (on appropriate distrib) makes output "Human" readable and still sorted by "reversed size" (sort -rh) Show Sample Output
0du -sh /home/*|sort -rh|head -n 10 -
without reverse...
0du -sm /home/* | sort -n | tail -10 -
0du -hd1 |sort -h
-
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.
0du -mx [directory] | grep -P '^\d{4}' | sort -rn -
Lists directory size up to a maximum traversal depth on systems like IBM AIX, where the du command doesn't have Linux's --max-depth option. AIX's du uses -g to display directory size on gigabytes, -m to use megabytes, and -k to use kilobytes. tr### is a Perl function that replaces characters and returns the amount of changed characters, so in this case it will return how many slashes there were in the full path name. Show Sample Output
0du -g | perl -ne 'print if (tr#/#/# == <maximum depth>)' -
0du -hs *
-
This will list all the files that are a gigabyte or larger in the current working directory. Change the G in the regex to be a M and you'll find all files that are a megabyte up to but not including a gigabyte. Show Sample Output
0du -hs * |egrep -i "^(\s?\d+\.?\d+G)" -
0du -k . | sort -rn | head -11
-
0sudo du -kx / |sort -n| awk '{print $1/(1000*1000) " G" ,$2}'
-
This command summarizes the disk usage across the files and folders in a given directory, including hidden files and folders beginning with ".", but excluding the directories "." and ".." It produces a sorted list with the largest files and folders at the bottom of the list Show Sample Output
0du -ks .[^.]* * | sort -n -
0du --max-depth=1 -h --apparent-size | sort -rh
- < 1 2 3 >
