using "touch" to create directories?
提问by LanceBaynes
1) in the "A" directory:
1）在“A”目录中：
find . -type f > a.txt
2) in the "B" directory:
2）在“B”目录中：
cat a.txt | while read FILENAMES; do touch "$FILENAMES"; done
3) Result: the 2) "creates the files" [i mean only with the same filename, but with 0 Byte size] ok. But if there are subdirs in the "A" directory, then the 2) can't create the files in the subdir, because there are no directories in it.
Question: is there a way, that touchcan create directories?
3）结果：2）“创建文件”[我的意思是只有相同的文件名，但大小为0字节]好的。但是如果“A”目录中有子目录，那么2）就不能在子目录中创建文件，因为里面没有目录。
问题：有没有办法touch可以创建目录？
采纳答案by thkala
Since findoutputs one file per line:
由于find每行输出一个文件：
cat a.txt | while read file; do
if [[ "$file" = */* ]]; then
mkdir -p "${file%/*}";
fi;
touch "$file";
done
EDIT:
编辑：
This would be slightly more efficient if the directories where created in a separate step:
如果在单独的步骤中创建目录，这会稍微更有效：
cat a.txt | grep / | sed 's|/[^/]*$||' | sort -u | xargs -d $'\n' mkdir -p
cat a.txt | while read file; do
touch "$file";
done
And, no, touchcannot create directories on its own.
而且，不，touch不能自己创建目录。
回答by Peter Taylor
No. Why not just use mkdir instead of touch for directories?
不。为什么不直接使用 mkdir 而不是 touch 目录？
