sed: can't read book/: 没有那个文件或目录 [英] sed: can't read book/ : No such file or directory

问题描述

我在 Red Hat Enterprise Linux Server 6.6 版(圣地亚哥)上运行了以下一行代码

I ran the following one line code on Red Hat Enterprise Linux Server release 6.6 (Santiago)

 grep -rl 'room' book/ | xargs sed -i 's/room/equipment/g'

我收到了以下消息

sed: can't read book/
book/del_entry_ajax.php: No such file or directory

其实我可以跑

grep -rl 'room' book/del_entry_ajax.php | xargs sed -i 's/room/equipment/g'

成功然后再次运行第一个命令，我得到了

successfully and then run the first command again, I got

sed: can't read book/
: No such file or directory

这是为什么，我该如何解决?

Why is that and how can I fix it?

推荐答案

当 GNU 人员给 grep 一个查找文件的选项时，他们真的搞砸了.有一个非常好的 UNIX 工具来查找文件，它有一个非常明显的名称 - find.试试这个:

The GNU guys really messed up when they gave grep an option to find files. There is a perfectly good UNIX tool to find files and it has a perfectly obvious name - find. Try this:

find book -type f -print0 | xargs -0 sed -i 's/room/equipment/g'
