删除指定后缀的文件脚本

!/bin/bash

使用方法: ./delete_files.sh /path/to/directory with|without extension

给脚本赋予可执行权限：chmod +x delete_files.sh

DIRECTORY=" $1" CONDITION="$ 2"
EXTENSION="$3"

检查参数

if [ -z " $DIRECTORY" ] || [ -z "$ CONDITION" ] || [ -z " $EXTENSION" ]; then echo "Usage:$ 0 /path/to/directory with|without extension"
echo "'with' : Delete files with the specified extension."
echo "'without' : Delete files without the specified extension."
exit 1
fi

根据条件删除文件

if [ " $CONDITION" == "with" ]; then # 删除指定后缀的文件 find "$ DIRECTORY" -type f -name "*. $EXTENSION" -exec rm -f {} + echo "Deleted all *.$ EXTENSION files in $DIRECTORY" elif [ "$ CONDITION" == "without" ]; then
# 删除非指定后缀的文件
find " $DIRECTORY" -type f ! -name "*.$ EXTENSION" -exec rm -f {} +
echo "Deleted all files NOT with *. $EXTENSION in$ DIRECTORY"
else
echo "Invalid condition: $CONDITION. Use 'with' or 'without'."
exit 1
fi
