利用shell脚本进行批量处理文件后缀名

#!/bin/bash

input_dir=$1

if [ -z "$input_dir" ]; then
    echo "Usage: ./rename.sh input_directory"
    exit 1
fi

cd "$input_dir" || exit

for file in *.csv.COMPLETED; do
    newname=$(echo $file | sed 's/\.COMPLETED//')
    mv "$file" "$newname"
done

#!/bin/bash
# 检查参数数量是否正确
if [ "$#" -ne 3 ]; then
    echo "Usage: $0 <path> <old_extension> <new_extension>"
    exit 1
fi

# 提取参数
path=$1
old_extension=$2
new_extension=$3

# 查找并修改文件后缀名
find "$path" -type f -name "*.$old_extension" -exec sh -c 'mv "$0" "${0%.$1}.$2"' {} $old_extension $new_extension \;
