Recently, my company website wants to host media files (user uploaded files) to some cloud storage service. But in preparation, we realized that our media folder is too big, about 48GiB. We need to delete unnecessary files to save the storage cost. Part of it, we need to hunt down big files.
I looked around to find a command to list largest files in Linux. Most of the tutorials on Internet tell you to use a combination of commands, which is often
du | sort | head, or
find | sort | head. None of them satisfies me, because:
duonly gives result of directories, not files.
$ du -hsx -- * | sort -rh | head -10 29G institution 4,2G picture 2,0G ckeditor-uploads 1,9G uploads 1,2G file 1,1G pl-report 698M school 586M articles 143M accommodation 120M institutions
findgive you non-human-friendly file size, and the command is too long and cryptic:
$ find . -type f -printf '%s %p\n'| sort -nr | head -10 127837320 ./file/2016/03/23/GuidebookIssue10_Compiled_Version_JPEG.pdf 102294295 ./institution/video/2019/08/07/Shannon_College_of_Hotel_Management.mp4 99698410 ./uploads/2019/08/14/easyuni_whatwedo_joshuachew.mp4 99601102 ./institution/video/2019/08/07/This_Is_RCSI.mp4 97910940 ./institution/video/2019/08/15/Baylor_Virtual_Tour__Academic_Excellence.mp4 97436072 ./institution/video/2019/07/31/Campus_Tour_ThinkDkIT.mp4 97350748 ./institution/video/2019/08/02/IT_Sligo_Open_Day.mp4 97251171 ./institution/video/2019/07/31/A_Day_in_the_Life_at_GMIT.mp4 95924392 ./institution/video/2019/07/08/Paris_Study_Tour_2_by_Sunway_Le_Cordon_Bleu.mp4 92570745 ./institution/video/2019/08/02/International_Students_at_Independent_College_Dublin.mp4
Someone tries to make the file size human-friendly by piping
xargs ls -lh. But it is very inefficient because that means each
findresult line will launch a process of
As a new fan of Rust, I looked around in Rust ecosystem and finally found a tool that fits me the best, dust. The command is simple, short, easy to remember:
$ dust -rF
-Fmeans showing files only.
-rmeans sorting reversly, biggest first.
Its display is also modern, by using graphical characters to build tree, and using colors.
I hope this post will pop up on Internet to help someones with similar need.
