mv: cannot stat error : No such file or directory error
提问by charlie
I need to move the files of a directory to another directory.I get stat error when I used the following program.
我需要将一个目录的文件移动到另一个目录。当我使用以下程序时出现 stat 错误。
for i in dir1/*.txt_dir; do
mv $i/*.txt dir2/`basename $i`.txt
done
error message
错误信息
mv: cannot stat `dir1/aa7.txt_dir/*.txt': No such file or directory
回答by John Kugelman
mv $i/*.txt dir2/`basename $i`.txt
This doesn't work when there are no text files in $i/. The shell passes the raw string "$i/*.txt"to mvwith the unexpanded *in it, which mvchokes on.
当$i/. 外壳将原始字符串传递"$i/*.txt"给mv其中未扩展的字符串*，它会mv窒息。
Try something like this:
尝试这样的事情：
for i in dir1/*.txt_dir; do
find $i -name '*.txt' -exec mv {} dir2/`basename $i`.txt \;
done

Normally, when a glob which does not match any filenames is expanded, it remains unchanged. Thus, you get results like this:
通常，当一个不匹配任何文件名的 glob 被扩展时，它保持不变。因此，您会得到如下结果：
$ rm .bak rm: cannot remove `.bak': No such file or directory
$ rm .bak rm: 无法删除 `.bak': 没有那个文件或目录
To avoid this we need to change the default value of nullglob variable.
为了避免这种情况，我们需要更改 nullglob 变量的默认值。
#BASH
shopt -s nullglob
for i in dir1/*.txt_dir; do
mv $i/*.txt dir2/'basename $i'.txt
done

Whilst it is not shown in your example - using the correct quotes is important. in BASH "*" evaluates to * and '*' evaluates to the expansion glob. so
虽然它没有在您的示例中显示 - 使用正确的引号很重要。在 BASH 中，"*" 的计算结果为 *，而 '*' 的计算结果为扩展全局。所以
`ls *`
will show all files in directory and
将显示目录中的所有文件和
`ls "*"`
will show all files named the literal *
将显示所有名为文字 * 的文件

when you put directory/* alone in for iteration, it list each file with absolute path. use `ls
当您单独放置 directory/* 进行迭代时，它会列出每个文件的绝对路径。使用`ls
for i in ls dir1/*.txt_dir; do
因为我在ls dir1/*.txt_dir；做
