搜索可执行文件

如果没有扩展名，有没有办法搜索并删除文件夹内的所有可执行文件？

例如，假设我有 4 个带有 .ubu 扩展名的文件，并且以下 bash 完成了我要求的工作：

rm *.ubu

例如_2现在假设我有 4 但是根本没有扩展，类似于：

测试 test_2 test_3 （chmod +x对其）

我该如何删除这些文件？

答案1

如果我们谈论的是设置了可执行位的文件，那么find命令就有-executable测试和-delete操作。

find /DIR/EC/TORY -type f -executable -delete

或者

find /DIR/EC/TORY -type f -executable -exec rm -f {} \;

应该可以解决问题。

要专门删除主目录中的所有可执行文件（不在子目录中），并询问您是否要删除每个文件，您可以执行以下操作

find ~ -type f -executable -maxdepth 0 -exec rm -i {} \;

从man find：

   -exec command ;
          Execute  command;  true  if 0 status is returned.  All following
          arguments to find are taken to be arguments to the command until
          an  argument  consisting of `;' is encountered.  The string `{}'
          is replaced by the current file name being processed  everywhere
          it occurs in the arguments to the command, not just in arguments
          where it is alone, as in some versions of find.  Both  of  these
          constructions might need to be escaped (with a `\') or quoted to
          protect them from expansion by the shell.  See the EXAMPLES sec‐
          tion for examples of the use of the -exec option.  The specified
          command is run once for each matched file.  The command is  exe‐
          cuted  in  the starting directory.   There are unavoidable secu‐
          rity problems surrounding use of the -exec  action;  you  should
          use the -execdir option instead.

   -exec command {} +
          This  variant  of the -exec action runs the specified command on
          the selected files, but the command line is built  by  appending
          each  selected file name at the end; the total number of invoca‐
          tions of the command will  be  much  less  than  the  number  of
          matched  files.   The command line is built in much the same way
          that xargs builds its command lines.  Only one instance of  `{}'
          is  allowed  within the command.  The command is executed in the
          starting directory.

要查找不带点的文件（或目录！），请使用扩展文件匹配模式

!(*.*)

您需要shopt -s extglob——我认为该选项在交互式 shell 中默认处于启用状态。

在 bash 中删除可执行文件

shopt -s extglob nullglob
for file in !(*.*); do
    [[ -f $file && -x $file ]] && echo rm "$file"
    # -f -> true if it's a file
    # -x -> true if it's executable
done

二进制文件将标记可执行位。

因此，您可以编写一个简单的 bash 脚本，检查是否设置了可执行位，如果是，则删除该文件。
