压缩与解压命令编辑

tar命令的选项和参数编辑

用法: tar [选项...] [文件]...
GNU 'tar' 命令可以将多个文件打成一个压缩包，也可以从压缩包中将文件解压出来。

示例:
  tar -cf archive.tar foo bar  # 将foo和bar打包为archive.tar
  tar -tvf archive.tar         # 完整列出archive.tar中的文件.
  tar -xf archive.tar          # 将archive.tar中所有的文件解压出来

 主要运行模式:

  -A, --catenate, --concatenate   向已有的tar包中添加文件
  -c, --create               创建一个新的tar包
  -d, --diff, --compare      比较tar包和文件系统的差别
      --delete               delete from the archive (not on mag tapes!)
  -r, --append               添加文件到包末尾
  -t, --list                 列出包中的内容
      --test-label           test the archive volume label and exit
  -u, --update               only append files newer than copy in archive

                             archives (default)

      --occurrence[=NUMBER]  process only the NUMBERth occurrence of each file
                             in the archive; this option is valid only in
                             conjunction with one of the subcommands --delete,
                             --diff, --extract or --list and when a list of
                             files is given either on the command line or via
                             the -T option; NUMBER defaults to 1
      --sparse-version=MAJOR[.MINOR]
                             set version of the sparse format to use (implies

                             在NUM前加'-', 打印除最后NUM个字节的所有内容
  -n, --lines=[-]NUM       打印前NUM行;
                             在NUM前加'-', 打印除最后NUM行的所有行
  -q, --quiet, --silent    打印前NUM行时不给出文件名
head的选项：


  -v, --verbose            打印前NUM行时给出文件名
  -z, --zero-terminated    行分隔符是NULL，而非换行符
tail的选项：
Mandatory arguments to long options are mandatory for short options too.
  -c, --bytes=[+]NUM       output the last NUM bytes; or use -c +NUM to
                             output starting with byte NUM of each file
  -f, --follow[={name|descriptor}]
                           output appended data as the file grows;
                             an absent option argument means 'descriptor'
  -F                       same as --follow=name --retry
  -n, --lines=[+]NUM       output the last NUM lines, instead of the last 10;
                             or use -n +NUM to output starting with line NUM
      --max-unchanged-stats=N
                           with --follow=name, reopen a FILE which has not
                             changed size after N (default 5) iterations
                             to see if it has been unlinked or renamed
                             (this is the usual case of rotated log files);
                             with inotify, this option is rarely useful
      --pid=PID            with -f, terminate after process ID, PID dies
  -q, --quiet, --silent    never output headers giving file names
      --retry              keep trying to open a file if it is inaccessible
  -s, --sleep-interval=N   with -f, sleep for approximately N seconds
                             (default 1.0) between iterations;
                             with inotify and --pid=P, check process P at
                             least once every N seconds
  -v, --verbose            always output headers giving file names
  -z, --zero-terminated    line delimiter is NUL, not newline
NUM可以有一个乘法器后缀:b 512, kB 1000, K 1024, MB 1000*1000, M 1024*1024, GB 1000*1000*1000, G 1024*1024*1024，等等，用于T, P, E, Z, Y。
