Question

所以我有这个 - 脚本检查输入文件夹中的重复文件...但是由于某种原因它只是没有工作，它真的开始让我感到沮丧......语法似乎从我在网上看到的内容来看是正确的

它只是没有正确循环 - 因为回声只输入一次，但是测试它的文件夹中有3个文件。我试图将第4行中的$ FOLDER位更改为/ stuff / *和stuff / *等实际名称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

Answer 1

您没有对文件进行路径名扩展。也许你想要：

for FILE in "$FOLDER"/*;

如果您想要定位具有特定扩展名的文件，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读取循环而不是find：

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