File Glob Patterns in Linux terminal

Question

I want to search a filename which may contain kavi or kabhi. I wrote command in the terminal:

ls -l *ka[vbh]i*

<

Answer 1

You can get what you want by using curly braces in bash:

ls -l *ka{v,bh}i*

Note: this is not a regular expression question so much as a "shell globbing" question. Shell "glob patterns" are different from regular expressions, though they are similar in many ways.
