对于文件中的 f，返回以空格分隔的部分

tag-icon • tag-icon command-line bash files
对于文件中的 f，返回以空格分隔的部分

我有以下代码

arrFiles[0]=0
cd "/home/thenok/Documents/Link to thought diary"
for i in $(find -type f ! -name "*~"); do
arrFiles[0]=$[arrFiles[0]+1]
arrFiles[arrFiles[0]]="$i" 
echo "    pos ${arrFiles[0]} file ${arrFiles[arrFiles[0]]}"
done

但它输出到（13 和 23 是文件）

pos 354 file ./Link
pos 355 file to
pos 356 file diary/201504/quint/13
pos 357 file ./Link
pos 358 file to
pos 359 file diary/201511/23

这很糟糕，因为当使用另一个命令（stat）而不是 echo 时，它会给我

stat: cannot stat ‘./Link’: No such file or directory
stat: cannot stat ‘to’: No such file or directory
stat: cannot stat ‘thought’: No such file or directory
stat: cannot stat ‘diary/201411/done/31’: No such file or directory

我尝试过：1：使用直接路径而不是链接，2：

arrFiles[0]=0
FILES="/home/thenok/Documents/Link to thought diary/*"
for i in "$FILES"; do
arrFiles[0]=$[arrFiles[0]+1]
arrFiles[arrFiles[0]]="$i" 
echo "    pos ${arrFiles[0]} file ${arrFiles[arrFiles[0]]}"
done
#result is pos 1 file /home/thenok/Documents/Link to thought diary/*

3：直接创建阵列而不使用子文件夹

arrFiles=( "/home/thenok/Documents/Link to thought diary/"* )
for f in "${arrFiles[@]}"
do
stat -c %s "$f"
echo "$f"
done

解决方案位于如何在带有空格的“for”循环中读取完整行这正是我最初想要的，但我不知道如何在谷歌中写入

IFS=$'\n'       # make newlines the only separator
arrFiles[0]=0
cd "/home/thenok/Documents/Link to thought diary"
for i in $(find "/home/thenok/Documents/Link to thought diary/" -type f ! -name "*~"); do
arrFiles[0]=$[arrFiles[0]+1]
arrFiles[arrFiles[0]]="$i" 
echo "    pos ${arrFiles[0]} file ${arrFiles[arrFiles[0]]}"
done

输出是

pos 10 file /home/thenok/Documents/Link to thought diary/Link to diary/201408/methinks questions.txt
pos 11 file /home/thenok/Documents/Link to thought diary/Link to diary/201408/methinks small.txt
pos 12 file /home/thenok/Documents/Link to thought diary/Link to diary/201408/methinks2.txt
pos 13 file /home/thenok/Documents/Link to thought diary/Link to diary/201408/methinkss.txt
pos 14 file /home/thenok/Documents/Link to thought diary/Link to diary/201408/myfile.txt
pos 15 file /home/thenok/Documents/Link to thought diary/Link to diary/201408/new  2.txt

答案1

为什么我的 shell 脚本会因空格或其他特殊字符而阻塞？

这样做：

FILES="/home/thenok/Documents/Link to thought diary/"
for f in "$FILES"/*
do
    stat "$f"
done

如果使用find，请使用其-exec命令：

find "/home/thenok/Documents/Link to thought diary/" -type f ! -name '*~' -exec stat {} +

永远不会做for f in $(find ...)。

如果需要数组，直接创建一个即可：

arrFiles=( "/home/thenok/Documents/Link to thought diary/"* )

然后做：

for f in "${arrFiles[@]}"
do
    stat -c %s "$f"
done

而不是循环索引。即使这样，您也不需要手动保存数组的长度。您可以通过 来获取它${#arrFiles[@]}。
