VI string search - UNIX for Dummies Questions & Answers

raysonliu · #1 (**permalink**) 05-23-2008

Hi,
Can anybody please tell how to find a match line in vi if the line contains Str_a or Str_b? Inside the vi, I tried

:/(Str_a|Str_b)

it didn't work. Also I tried

:/\(Str_a|Str_b\)

didn't work either.

Thanks,

Hi,

For single character strings surround search with square brackets. If searching for 'a' and 'k' command would be /[ak]. To seach for 'a' to 'k' command is \[a-k].

Not sure if this helps you.
