阅读文件列表复制删除的文件回 [英] Read list of files and copy deleted files back
问题描述
我做了一个善变的合并而注销的时候我需要在新的分支，所以我产生被删除的文件的列表，我现在试图建立一个shell脚本复制删除的文件回来，但到目前为止的一些文件是不working.The脚本的问题是
猫deltedfiles | xargs的-I {}的bash -c'切-d-f1{}| grep的-fqR和放大器;＆安培;回波{}'
有人可以告诉我，我该如何纠正呢？
我刚刚得到削减一个错误，指出该文件不存在，整个行，我明白要被切断是把它当作一个文件。
编辑：
我创建的文件列表，并将其保存到使用汞状态的文本文件名为deletdfiles。
在剧本我会在与cp命令结束，这只是更换回声测试，如果我能得到ATLEAST它呼应。
该deltedfiles看起来喜欢这个

运行上面的命令后，这是输出
切，R蟒蛇/ cmsintegration /事件/迁移/ 0002_improved_navigation.py：没有这样的文件或目录
切，R蟒蛇/ cmsintegration /事件/迁移/ 0003_sitemap_fields.py：没有这样的文件或目录

切，R蟒蛇/ cmsintegration /事件/迁移/ 0008_adding_mob_reg_link.py：没有这样的文件或目录
如果我理解正确的问题，这样的事情可以工作：
$同时读取-r _文件;不要回声$文件otherdir / $文件;完成＆LT; deltedfiles

替换回声与 CP ，如果它产生正确的输出。
如果您只想复制都以单词开始的行中的文件研究你
能做到这一点是这样的：
同时读取-r字母的文件_;做[[$信=R]]＆放大器;＆安培;回声$文件otherdir / $文件;完成＆LT; deltedfiles
另外，在一个更易读的格式：
同时读取-r字母的文件_
做
[[$信=R]]＆放大器;＆安培;回声$文件otherdir / $文件
完成＆LT; deltedfiles
I did a mercurial merge which deleted a few files which i need in the new branch so i generated a list of the deleted files and am now trying to build a shell script to copy the deleted files back but so far it is not working.The script is question is
cat deltedfiles | xargs -I {} bash -c 'cut -d" " -f1 "{}"|grep -Fq "R" && echo {}'
Can somebody tell me how do i correct this? I just get an error from cut saying that the file does not exist and the whole line which i understand to be is cut is treating it as a file.
EDIT: I created the list of files and saved it to a text file named deletdfiles using hg status. In the script i'll replace echo at the end with cp command this was just to test if i can atleast get it to echo.
The deltedfiles looks likes this
cat deltedfiles

If I understand the problem correctly, something like this could work:

Replace echo with cp if it produces the correct output.
If you only want to copy the files that are in a line that starts with the word R you
can do it like this:
while read -r letter file _ ; do [[ $letter = "R" ]] && echo "$file" "otherdir/$file"; done < deltedfiles
Or in a more readable format:
while read -r letter file _
do
[[ $letter = "R" ]] && echo "$file" "otherdir/$file"
done < deltedfiles
