我开始编写一个简单的 bash shell 脚本，以使用 SHA1 检测匹配项来查找给定目录中的重复文件。一切正常，直到我遇到带空格的文件名。检测仍然有效，但在输出中空格被转换为换行符。

剧本...

#!/bin/bash
export TARGET=$1
find $TARGET -type f -exec openssl sha1 \{\} \; > ./dupes.txt
COUNT=-1
for EVALUATION in `cat ./dupes.txt | sed 's/SHA1(\(.*\))\= \(.*\)$/\2 \1/' | awk '{print $1}' | sort | uniq -c | sort -nr`
do
    if [[ $COUNT == -1 ]]
    then
        COUNT=$EVALUATION
    else 
        HASH=$EVALUATION
        if [[ $COUNT == 1 ]]
        then
            break
        fi
        echo "--- duplicate set ---"
        for FILE in `grep $HASH ./dupes.txt | awk -F"[()]+" '{print $2}'`
        do
            echo "$FILE"
        done
        echo "---------------------"
        COUNT=-1
    fi
done

像这样运行脚本...

./dupes.sh /home/dacracot/testDupes

它将创建一个看起来像...的文件 dupes.txt

SHA1(/home/dacracot/testDupes/lP3wj.jpg)= 324d91f412745481ed38aa184e5a56bfc3bf43b5

最后输出看起来像......

--- duplicate set ---
/home/dacracot/testDupes/tae
2.svg
/home/dacracot/testDupes/tae.svg
---------------------

但是正如您从第一个文件中看到的那样，输出应该是...

--- duplicate set ---
/home/dacracot/testDupes/tae 2.svg
/home/dacracot/testDupes/tae.svg
---------------------

什么将空格更改为换行符？

bash grep
