击。 当我使用files =`find…`找到文件时，然后使用for循环“ for $ files中的文件”。 如何访问找到的文件的路径？

Question

 files=`find C:/PATH/TO/DIRECTORY -name *.txt`

 for file in $files; do
 #need code to rename $file, by moving it into the same directory

eg. $file was found in C:/PATH/TO/DIRECTORY/2014-05-08. how do I rename $file to back to that directory and not to C:/PATH/TO/DIRECTORY?

Answer 1

You can use -execdir option in find:

find C:/PATH/TO/DIRECTORY -name '*.txt' -execdir mv '{}' '{}'-new \;

As per man find :

-execdir utility [argument ...] ;

The -execdir primary is identical to the -exec primary with the exception that utility will be executed from the directory that holds the current file.

Answer 2

find C:/PATH/TO/DIRECTORY -name \*.txt | while read file
do
   dir=$(dirname "$file")
   base=$(basename "$file")
   mv "$file" "$dir/new_file_name"
done

Answer 3

You would be better served by using this structure:

while read fname
do
  ....
done < <(find ...)

Or, if you're not using bash :

find ... | while read fname
do
  ....
done

The problem with storing the output of find in a variable, or even doing for fname in $(find ...) , is with word splitting on whitespace. The above structures still fail if you have a file name with a newline in it, since they assume that you have one file name per line, but they're better than what you have now.

An even better solution would be something like this:

find ... -print0 | xargs -0 -n1 -Ixxx somescript.sh "xxx"

But even that might have issues if filenames have quotes or other things in them.

The bottom line is that parsing arbitrary data (which filenames can be) is hard...
