Question

我做了一个mercurial merge，它删除了我在新分支中需要的一些文件，所以我生成了一个已删除文件的列表，现在我正在尝试构建一个shell脚本来复制已删除的文件，但到目前为止它还没有working.The script is question is

cat deltedfiles | xargs -I {} bash -c 'cut -d" " -f1 "{}"|grep -Fq "R" && echo {}'

有人可以告诉我如何更正此问题？我只是从剪切中得到一个错误，说该文件不存在，并且我理解的整条线被切割为将其视为文件。

编辑：我创建了文件列表并使用hg status将其保存到名为deletdfiles的文本文件中。在脚本中，我将用cp命令替换最后的echo，这只是为了测试我是否至少可以让它回显。

detedfiles看起来像这样

cat deltedfiles

cat deltedfiles
R python/cmsintegration/events/migrations/0002_improved_navigation.py
R python/cmsintegration/events/migrations/0003_sitemap_fields.py

R python/cmsintegration/events/migrations/0007_compute_nav_order.py
R python/cmsintegration/events/migrations/0008_adding_mob_reg_link.py

运行上述命令后，这是输出

如果我理解正确的问题，这样的事情可能有效：

$ while read -r _ file; do echo "$file" "otherdir/$file"; done < deltedfiles
python/cmsintegration/events/migrations/0002_improved_navigation.py newfolder/python/cmsintegration/events/migrations/0002_improved_navigation.py
python/cmsintegration/events/migrations/0003_sitemap_fields.py newfolder/python/cmsintegration/events/migrations/0003_sitemap_fields.py
python/cmsintegration/events/migrations/0004_cache_differentiation.py newfolder/python/cmsintegration/events/migrations/0004_cache_differentiation.py
python/cmsintegration/events/migrations/0005_cms_displayables_seo.py newfolder/python/cmsintegration/events/migrations/0005_cms_displayables_seo.py
python/cmsintegration/events/migrations/0006_nav_has_changed.py newfolder/python/cmsintegration/events/migrations/0006_nav_has_changed.py
python/cmsintegration/events/migrations/0007_compute_nav_order.py newfolder/python/cmsintegration/events/migrations/0007_compute_nav_order.py
python/cmsintegration/events/migrations/0008_adding_mob_reg_link.py newfolder/python/cmsintegration/events/migrations/0008_adding_mob_reg_link.py

如果echo生成正确的输出，请将cp替换为R。

如果您只想复制以单词while read -r letter file _ ; do [[ $letter = "R" ]] && echo "$file" "otherdir/$file"; done < deltedfiles开头的行中的文件可以这样做：

while read -r letter file _ 
do 
    [[ $letter = "R" ]] && echo "$file" "otherdir/$file"
done < deltedfiles

或者以更易读的格式：

{{1}}

读取文件列表并将已删除的文件复制回来
