List all files not starting with a number
提问by Pavan Manjunath
I want to examine the all the key files present in my /proc. But /prochas innumerable directories corresponding to the running processes. I don't want these directories to be listed. All these directories' names contain only numbers. As I am poor in regular expressions, can anyone tell me whats the regexthat I need to send to lsto make it NOTto search files/directories which have numbers in their name?
我想检查我的/proc. 但是/proc有无数的目录对应于正在运行的进程。我不想列出这些目录。所有这些目录的名称都只包含数字。由于我在正则表达式方面很差，有人能告诉我regex我需要发送什么ls来使它不搜索名称中包含数字的文件/目录吗？
UPDATE: Thanks to all the replies! But I would love to have a lsalone solution instead of ls+grepsolution. The lsalone solutions offered till now doesn't seem to be working!
更新：感谢所有回复！但我希望有一个ls单独的解决方案而不是ls+grep解决方案。ls到目前为止提供的单独解决方案似乎不起作用！

All files and directories in /procwhich do not contain numbers (in other words, excluding process directories):
所有/proc不包含数字的文件和目录（换句话说，不包括进程目录）：
ls -d /proc/[^0-9]*
All files recursively under /procwhich do not start with a number:
所有/proc不以数字开头的递归文件：
find /proc -regex '.*/[0-9].*' -prune -o -print
Butthis will also exclude numeric files in subdirectories(for example /proc/foo/bar/123). If you want to exclude only the top-level files with a number:
但这也将排除子目录中的数字文件（例如/proc/foo/bar/123）。如果您只想排除带有数字的顶级文件：
find /proc -regex '/proc/[0-9].*' -prune -o -print
Hold on again! Doesn't this mean that any regular filescreated by touch /proc/123or the like will be excluded? Theoretically yes, but I don't think you can do that. Try creating a file for a PID which does not exist:
再坚持一下！这是否意味着将排除由之类创建的任何常规文件touch /proc/123？理论上是的，但我认为你做不到。尝试为不存在的 PID 创建文件：
$ sudo touch /proc/123
touch: cannot touch `/proc/123': No such file or directory

Use grep with -vwhich tells it to print all lines not matchingthe pattern.
使用 grep-v告诉它打印所有与模式不匹配的行。
ls /proc | grep -v '[0-9+]'

Following regex matches all the characters except numbers
以下正则表达式匹配除数字以外的所有字符
^[\D]+?$
Hope it helps !
希望能帮助到你 ！

ls /proc | grep -v -E '[0-9]+'
ls /proc | grep -v -E '[0-9]+'
回答by Mithrandir
You don't need grep, just ls:
您不需要 grep，只需ls：
ls -ad /proc/[^0-9]*
if you want to search the whole subdirectory structure use find:
如果要搜索整个子目录结构，请使用 find：
find /proc/ -type f -regex "[^0-9]*" -print

For the sake of of completion. You may apply Mithandir's answer with find.
为了完成。您可以通过 find 应用 Mithandir 的答案。
find . -name "[^0-9]*" -type f
