在 Linux 中查找多个文件并重命名它们

发布于05月14日

我在Suse 10系统中有a_dbg.txt, b_dbg.txt ...个这样的文件.我想编写一个bash shell脚本，通过从这些文件中删除"_dbg"来重命名这些文件.

谷歌建议我使用rename命令.所以我在CURRENT_FOLDER上执行了rename _dbg.txt .txt *dbg*命令

我的实际CURRENT_FOLDER包含以下文件.

CURRENT_FOLDER/a_dbg.txt
CURRENT_FOLDER/b_dbg.txt
CURRENT_FOLDER/XX/c_dbg.txt
CURRENT_FOLDER/YY/d_dbg.txt

执行rename命令后，

CURRENT_FOLDER/a.txt
CURRENT_FOLDER/b.txt
CURRENT_FOLDER/XX/c_dbg.txt
CURRENT_FOLDER/YY/d_dbg.txt

它不是递归的，如何使这个命令重命名所有子目录中的文件.像XX和YY，我将有这么多子目录的名称是不可预测的.我的CURRENT_FOLDER也会有一些其他的文件.

推荐答案

可以使用find递归查找所有匹配的文件:

$ find . -iname "*dbg*" -exec rename _dbg.txt .txt '{}' \;

EDIT: '{}'和\;是什么？

-exec参数使find对找到的每个匹配文件执行rename.'{}'将替换为文件的路径名.最后一个标记\;仅用于标记exec表达式的结束.

所有这些都在find的手册页中进行了很好的描述:

 -exec utility [argument ...] ;
         True if the program named utility returns a zero value as its
         exit status.  Optional arguments may be passed to the utility.
         The expression must be terminated by a semicolon (``;'').  If you
         invoke find from a shell you may need to quote the semicolon if
         the shell would otherwise treat it as a control operator.  If the
         string ``{}'' appears anywhere in the utility name or the argu-
         ments it is replaced by the pathname of the current file.
         Utility will be executed from the directory from which find was
         executed.  Utility and arguments are not subject to the further
         expansion of shell patterns and constructs.
