问题描述

限时删除!!

我运行Debian中8.1,GNU bash的版本30年3月4日(1) - 释放下(x86_64-PC-Linux的GNU)和联想G50-30 500 GB固态硬盘和8 GB闪存:

I run in Debian 8.1, GNU bash, version 4.3.30(1)-release (x86_64-pc-linux-gnu) and Lenovo G50-30 with 500 GB SSD and 8 GB flash memory:

shopt -s extglob
cp -r !(Backups.backupdb/) /home/masi/Documents/

但它也将一切从目录复制的 Backups.backupdb / 的证实在复印结束。

2小时后,复制

cp: cannot stat ‘Backups.backupdb/masi\’s MacBook Air/2015-06-25-233115/Macintosh HD/System/Library/Image Capture/Automatic Tasks/MakePDF.app/Contents/Resources/ko.lproj/3x5로 자르기.mkpdf’: No such file or directory
cp: cannot stat ‘Backups.backupdb/masi\’s MacBook Air/2015-06-25-233115/Macintosh HD/System/Library/Image Capture/Automatic Tasks/MakePDF.app/Contents/Resources/ko.lproj/3x5에 맞추기.mkpdf’: No such file or directory
...

cp: cannot stat ‘cardio bad/extreme_90_180.swf’: Invalid argument
cp: cannot stat ‘Cardio databases tools’: Invalid argument
cp: cannot stat ‘Cardiology’: Invalid argument
...

在这里我把意想不到的浏览通过备份文件夹。
这里的挑战是,Backups.backupdb是几TB的,看到了它去浏览它感觉并不好。

where I keep unexpected browsing through the backup folder.The challenge here is that the Backups.backupdb is several TBs and seeing that it goes browsing it does not feel good.

我运行

ls -lR /media/masi/eb807ed8-7f45-35f8-a345-9da6692b228a/ |grep Backup

获得

ls: cannot access /media/masi/eb807ed8-7f45-35f8-a345-9da6692b228a/Cancer: Invalid argument
ls: cannot access /media/masi/eb807ed8-7f45-35f8-a345-9da6692b228a/Cardio databases tools: Invalid argument
ls: cannot access /media/masi/eb807ed8-7f45-35f8-a345-9da6692b228a/Cardiology: Invalid argument
drwxr-xr-x 1 root root          7 Jul  8 20:25 Backups.backupdb
ls: cannot open directory /media/masi/eb807ed8-7f45-35f8-a345-9da6692b228a/animations/Embryology/e17_files: Permission denied
^C

所以目录不是一个符号链接。
为什么extglob情况除外通过浏览文件夹这里被打破?

so the directory is not a symlink.Why is extglob except condition broken here by browsing the folder?

推荐答案

尝试删除反斜杠(我添加用于测试目的回声):

Try removing the backslash (I am adding echo for test purposes):

shopt -s extglob
echo cp -r !(Backups.backupdb) /home/masi/Documents/

它工作在我的环境(GNU bash中,版本30年3月4日,OS X)

It works in my environment (GNU bash, version 4.3.30, OS X)
