1 ubuntu中如何将终端添加到右键

/home/cui/.local/share/nautilus/scripts
#!/bin/bash

#cd $NAUTILUS_SCRIPT_CURRENT_URI   
#当前目录

cd  $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS

#选中文件目录
exec gnome-terminal

2 获取文件夹大小

du -h --max-depth=
cui@bug:~/ide$ du --help

用法：du [选项]... [文件]...

　或：du [选项]... --files0-from=F

Summarize disk usage of each FILE, recursively for directories.

Mandatory arguments to long options are mandatory for short options too.

  -, --null            end each output line with  byte rather than 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 ,, 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)　//指定显示大小信息的深度　若为１,即当前目录下文件和文件夹大小

                          only if it is N or fewer levels below the command

                          line argument;  --max-depth= 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) //人类刻度　　不指定返回字节，指定返回　ｋｂ　　ＭＢ

  -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   do not include size of subdirectories

      --si              like -h, but use powers of  not

  -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 STYLE:

                          full-iso, long-iso, iso, +FORMAT

                          FORMAT is interpreted like '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        显示此帮助信息并退出

      --version        显示版本信息并退出

所显示的数值是来自 --block-size、DU_BLOCK_SIZE、BLOCK_SIZE

及 BLOCKSIZE 环境变量中第一个可用的 SIZE 单位。

否则，默认单位是  字节(或是 ，若设定 POSIXLY_CORRECT 的话)。

SIZE is an integer and optional unit (example: 10M is **).  Units

are K, M, G, T, P, E, Z, Y (powers of ) or KB, MB, ... (powers of ).
