背景
みんなで共用で使用しているパソコンの容量が圧迫されている
これでデータセットを置いたらパソコンをこわしてしまうかも、気まずい😢
👇
Filesystem Size Used Avail Use% Mounted on
udev 504G 0 504G 0% /dev
tmpfs 101G 51M 101G 1% /run
/dev/sda4 876G 48G 828G 6% /

000.000.00.0:/home/data 14T 14T 711G 96% /data
コマンド
duコマンドを使用する！
du：ディスクの使用量を表す
今回使ったコマンド
du -h -d <検索する深さ>
-h：容量のサイズに適した、読みやすい単位で表示
-d：ディレクトリの深さを指定
結果例
563G ./a
190M ./b
3.0T ./m
0 ./dataset
18G ./o
36G ./i
706G ./w
1.3T ./t
3.7T ./a
0 ./project
141G ./h
0 ./try
9.3T .
これで特定できたので、容量が大きい人に連絡してみます

$ du --help
Usage: du [OPTION]... [FILE]...
or: du [OPTION]... --files0-from=F
Summarize disk usage of the set of FILEs, recursively for directories.
Mandatory arguments to long options are mandatory for short options too.
-0, --null end each output line with NUL, not newline
-a, --all write counts for all files, not just directories
--apparent-size print apparent sizes, rather than disk usage; although
the apparent size is usually smaller, it may be
larger due to holes in ('sparse') files, internal
fragmentation, indirect blocks, and the like
-B, --block-size=SIZE scale sizes by SIZE before printing them; e.g.,
'-BM' prints sizes in units of 1,048,576 bytes;
see SIZE format below
-b, --bytes equivalent to '--apparent-size --block-size=1'
-c, --total produce a grand total
-D, --dereference-args dereference only symlinks that are listed on the
command line
-d, --max-depth=N print the total for a directory (or file, with --all)
only if it is N or fewer levels below the command
line argument; --max-depth=0 is the same as
--summarize
--files0-from=F summarize disk usage of the
NUL-terminated file names specified in file F;
if F is -, then read names from standard input
-H equivalent to --dereference-args (-D)
-h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)
--inodes list inode usage information instead of block usage
-k like --block-size=1K
-L, --dereference dereference all symbolic links
-l, --count-links count sizes many times if hard linked
-m like --block-size=1M
-P, --no-dereference don't follow any symbolic links (this is the default)
-S, --separate-dirs for directories do not include size of subdirectories
--si like -h, but use powers of 1000 not 1024
-s, --summarize display only a total for each argument
-t, --threshold=SIZE exclude entries smaller than SIZE if positive,
or entries greater than SIZE if negative
--time show time of the last modification of any file in the
directory, or any of its subdirectories
--time=WORD show time as WORD instead of modification time:
atime, access, use, ctime or status
--time-style=STYLE show times using STYLE, which can be:
full-iso, long-iso, iso, or +FORMAT;
FORMAT is interpreted like in 'date'
-X, --exclude-from=FILE exclude files that match any pattern in FILE
--exclude=PATTERN exclude files that match PATTERN
-x, --one-file-system skip directories on different file systems
--help display this help and exit
--version output version information and exit
Display values are in units of the first available SIZE from --block-size,
and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables.
Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set).
The SIZE argument is an integer and optional unit (example: 10K is 10*1024).
Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000).
Binary prefixes can be used, too: KiB=K, MiB=M, and so on.
