Answer 1

This is a good article: How to Find Out Top Directories and Files (Disk Space) in Linux

One of the commands listed comes close to your directory needs:

$ du -Sh | sort -rh | head -20
8.0G    ./Videos
990M    ./.googleearth/Cache/unified_cache_leveldb_leveldb2
798M    ./.cache/mozilla/firefox/9fu0cuql.default/cache2/entries
643M    ./roboto/Kijiji
378M    ./android-studio/lib
306M    ./roboto
293M    ./Pictures
195M    ./.dropbox-dist/dropbox-lnx.x86_64-84.4.170
193M    ./.cache/google-chrome/Default/Cache
193M    ./Android/Sdk/emulator/qemu/linux-x86_64
177M    ./android-studio/plugins/android/lib/layoutlib/data/fonts
131M    ./.cache/thumbnails/large
130M    ./android-studio/plugins/android/lib
102M    ./.gradle/wrapper/dists/gradle-4.6-all/bcst21l2brirad8k2ben1letg

91M     ./.mozilla/firefox/9fu0cuql.default
90M     ./Android/Sdk/emulator/lib64/qt/lib
80M     ./gmail
80M     ./Downloads

Another of the commands comes close to solving your file size needs:

$ find -type f -exec du -Sh {} + | sort -rh | head -n 20
2.8G    ./Videos/simplescreenrecorder-2019-11-24_17.20.17.mkv
1.3G    ./Videos/simplescreenrecorder-2019-12-01_18.56.29.mkv
1.1G    ./Videos/simplescreenrecorder-2019-11-30_16.16.22.mkv
1.1G    ./Videos/simplescreenrecorder-2019-11-17_18.13.03.mkv
952M    ./Videos/simplescreenrecorder-2019-11-11_21.42.51.mkv
548M    ./Videos/simplescreenrecorder-2019-11-24_20.03.44.mkv
201M    ./Videos/Screencapture 2019-11-08 at 13.07.14.mp4
122M    ./Videos/Screencapture 2019-11-08 at 13.43.55.mp4
102M    ./.gradle/wrapper/dists/gradle-4.6-all/bcst21l2brirad8k2ben1letg/gradle-4.6-all.zip
88M     ./android-studio/lib/platform-impl.jar
66M     ./android-studio/bin/lldb/lib/liblldb.so.7
63M     ./android-studio/jre/jre/lib/rt.jar
62M     ./.AndroidStudio3.2/system/caches/content.dat.storageData
61M     ./android-studio/lib/idea.jar
57M     ./.config/VirtualBox/VBoxGuestAdditions_5.1.38.iso
54M     ./Documents/vio.mp4
48M     ./android-studio/plugins/android/lib/android.jar
46M     ./Downloads/linux-modules-4.14.153-0414153-generic_4.14.153-0414153.201911101449_amd64.deb
45M     ./Android/Sdk/platforms/android-28/android.jar
42M     ./android-studio/lib/java-impl.jar

In both examples, just tweak the number of lines listed to get files over 100 MB. For example change head -n 20 to head -n 40 to list double the number of files.

Answer 2

You can simply use find command in order to display only file which are bigger than 100 MB, like that :

sudo find -size +100000k

Explanation :

• find -size would display all files depending of -size option parameter
• +100000k would say bigger than 100 000 KB, which is 100 MB

NB : if you aren't inside a subdirectory of your home directory or something like /home/user or /media, you need to use sudo command, or you won't be able to list every files due to Permission denied
