Bash 运行脚本以检查重复文件-安装失败

所以我有一个脚本，它检查一个输入文件夹中是否有重复的文件…但由于某种原因它不起作用，它真的开始让我感到沮丧…从我在网上看到的情况来看，语法似乎是正确的

它只是不能正常循环-因为回音只输入一次，但是我正在测试的文件夹中有3个文件。我尝试将第4行中的$FOLDER位更改为实际名称，如/stuff/*和stuff/*以及stuff 我正在测试的文件夹的名称。有什么想法吗

FOLDER=$1
mkdir check

for FILE in $FOLDER;
do
echo $FILE


CHECKSUM=$(cksum $FILE|awk '{print $1}')
if [[ -e check/$CHECKSUM ]];then
echo Duplicate at $FILE
rm $FILE

else

touch check/$CHECKSUM
echo "check/$CHECKSUM"

fi

您没有对文件进行路径名扩展。也许你想要：

for FILE in "$FOLDER"/*;

如果要以具有特定扩展名的文件为目标，请执行以下操作：

for FILE in "$FOLDER"/*.ext;

测试文件是否真的是文件而不是目录也是一件好事：

for FILE in "$FOLDER"/*; do
    if [[ -f $FILE ]]; then

如果要递归处理文件，请使用while read循环代替find：

只使用fdupes如何？您在结尾缺少一个done。您不需要在…中的文件后面加分号。。。。如果任何文件的名称中有空格，则应将所有出现的$FILE用双引号括起来。

while IFS= read FILE; do
    ...
done < <(exec find "$FOLDER" -type f)
