本文介绍了一个实用的Shell脚本，该脚本能够帮助用户将指定目录下的所有文件名转换为统一的小写或大写格式。通过简单的命令行操作即可实现文件名的批量修改，适用于需要标准化文件名格式的场景。

#!/bin/sh
# Usage: ./loworup.sh <-l | -u> <target_directory>

if [ $# -ne 2 ] ; then
     echo "Usage: ${0} <-l | -u> <target_directory>"
     exit 1
fi
if [ ! -d ${2} -o "${1}" != "-l" -a "${1}" != "-u" ] ; then
     echo "Usage: ${0} <-l | -u> <target_directory>"
     exit 1
fi
exec 1>/dev/null 2>&1
dir=`dirname "${2}"`
cd ${dir}
if [ "${1}" = "-l" ] ; then
     base=`basename "${2}" | tr "[A-Z]" "[a-z]"`
else
     base=`basename "${2}" | tr "[a-z]" "[A-Z]"`
fi
mv -f "`basename ${2}`" "${base}"
for entry in `find ${base}`
do
     before="."

     for after in `echo "${entry}" | sed -e 's,/, ,g'`
     do
         tmp_entry="${before}/${after}"
         if [ "${1}" = "-l" ] ; then
             before=`echo "${tmp_entry}" | tr "[A-Z]" "[a-z]"`
         else

done
