linux terminal 日常shell

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 ).
