for f in `find`; do mv -v "$f" "`echo $f | tr '[A-Z]' '[a-z]'`"; done

MacOS,

安装重命名包，

brew install rename

Use,

find . -iname "*.py" -type f | xargs -I% rename -c -f  "%"                       

该命令查找所有扩展名为*.py的文件，并将文件名转换为小写。

`f` - forces a rename

例如,

$ find . -iname "*.py" -type f
./sample/Sample_File.py
./sample_file.py
$ find . -iname "*.py" -type f | xargs -I% rename -c -f  "%"
$ find . -iname "*.py" -type f
./sample/sample_file.py
./sample_file.py

一行程序:

for F in K*; do NEWNAME=$(echo "$F" | tr '[:upper:]' '[:lower:]'); mv "$F" "$NEWNAME"; done

甚至:

for F in K*; do mv "$F" "${F,,}"; done

注意，这将只转换以字母K开头的文件/目录，因此要相应地进行调整。

这是一个小的shell脚本，做你所要求的:

root_directory="${1?-please specify parent directory}"
do_it () {
    awk '{ lc= tolower($0); if (lc != $0) print "mv \""  $0 "\" \"" lc "\"" }' | sh
}
# first the folders
find "$root_directory" -depth -type d | do_it
find "$root_directory" ! -type d | do_it

注意第一个find中的-depth动作。

在这种情况下，我会使用Python，以避免乐观地假设没有空格或斜杠的路径。我还发现python2往往被安装在更多的地方，而不是重命名。

#!/usr/bin/env python2
import sys, os

def rename_dir(directory):
  print('DEBUG: rename('+directory+')')

  # Rename current directory if needed
  os.rename(directory, directory.lower())
  directory = directory.lower()

  # Rename children
  for fn in os.listdir(directory):
    path = os.path.join(directory, fn)
    os.rename(path, path.lower())
    path = path.lower()

    # Rename children within, if this child is a directory
    if os.path.isdir(path):
        rename_dir(path)

# Run program, using the first argument passed to this Python script as the name of the folder
rename_dir(sys.argv[1])

在OS X中，mv -f显示“same file”错误，所以我重命名两次:

for i in `find . -name "*" -type f |grep -e "[A-Z]"`; do j=`echo $i | tr '[A-Z]' '[a-z]' | sed s/\-1$//`; mv $i $i-1; mv $i-1 $j; done
