推荐答案
执行此操作的一种好方法是使用扩展的glob.有了它们，您可以在Bash上执行正则表达式.
A nice way to do this is to use extended globs. With them, you can perform regular expressions on Bash.
要启动，您必须启用extglob功能，因为默认情况下它已禁用:
To start you have to enable the extglob feature, since it is disabled by default:
shopt -s extglob
然后，编写具有以下条件的正则表达式:stuff + ka + v或bh + i + stuff.在一起:
Then, write a regex with the required condition: stuff + ka + either v or bh + i + stuff. All together:
ls -l *ka@(v|bh)i*
语法与常规正则表达式略有不同，因此您需要阅读扩展的globs 那...
The syntax is a bit different from the normal regular expressions, so you need to read in Extended Globs that...
