获取特定的字符串 [英] Get specific string

问题描述

我需要从一个更大的字符串获取特定的字符串：

I need to get a specific string from a bigger string:

从这些 Abcd1234_Tot9012_tore.dr 或 Abcd1234_Tot9012.tore.dr

我要得到那些托特和之间的数字_ 或。，所以我应该得到 9012 。重要的是，前和这些数字后的字符数可以变化。

I want to get those numbers which are between Tot and _ or . , so I should get 9012. Important thing is that the number of characters before and after these numbers may vary.

谁能给我提供了很好的解决方案？在此先感谢！

Could anyone give me a nice solution for this? Thanks in advance!

推荐答案

这也应该，如果你正在寻找只为托特后的数字工作

This should also work if you are looking only for numbers after Tot

[srikanth@myhost ~]$ echo "Abcd1234_Tot9012_tore.dr" | awk ' { match($0,/Tot([0-9]*)/,a); print a[1]; } '
9012
[srikanth@myhost ~]$ echo "Abcd1234_Tot9012.tore.dr" | awk ' { match($0,/Tot([0-9]*)/,a); print a[1]; } '
9012
