当文件名存在时，从终端中提取zip并进行重命名？

用户名

我正在关注这个问题以提取一个zip文件。如果存在具有相同名称的现有文件，是否可以在提取的文件后自动添加数字？

例如，我有example.zip一个名为的文件contents.csv。我的目录是这样的：

contents.csv   example.zip

当前，当我解压缩文件夹时，会提示我：

$ unzip example.zip
Archive:  example.zip
replace contents.csv? [y]es, [n]o, [A]ll, [N]one, [r]ename: y

相反，我只想运行unzip example.zip然后-1在发生冲突的情况下在文件名后自动添加一个数字（）：

contents-1.csv   contents.csv   example.zip

unzip example.zip再次运行将得到以下结果：

contents-2.csv   contents-1.csv   contents.csv   example.zip

一些GUI软件已经做到了这一点，但是我想通过脚本来实现。

您可以使用-B开关进行操作。

   -B     [when compiled with UNIXBACKUP defined] save a  backup  copy  of
          each  overwritten  file. The backup file is gets the name of the
          target file with a tilde and optionally a unique sequence number
          (up to 5 digits) appended.  The sequence number is applied when‐
          ever another file with the  original  name  plus  tilde  already
          exists.   When used together with the "overwrite all" option -o,
          numbered backup files are  never  created.  In  this  case,  all
          backup  files  are  named  as the original file with an appended
          tilde, existing backup files are deleted without  notice.   This
          feature  works  similarly to the default behavior of emacs(1) in
          many locations.

          Example: the old copy of ``foo'' is renamed to ``foo~''.

          Warning: Users should be aware that the -B option does not  pre‐
          vent  loss  of existing data under all circumstances.  For exam‐
          ple, when unzip  is  run  in  overwrite-all  mode,  an  existing
          ``foo~'' file is deleted before unzip attempts to rename ``foo''
          to ``foo~''.  When this rename attempt fails (because of a  file
          locks,  insufficient  privileges,  or  ...),  the  extraction of
          ``foo~'' gets cancelled, but the  old  backup  file  is  already
          lost.   A  similar scenario takes place when the sequence number
          range for numbered backup files gets exhausted (99999, or  65535
          for  16-bit  systems).   In  this case, the backup file with the
          maximum sequence number is  deleted  and  replaced  by  the  new
          backup version without notice.
