Below samle could find the "ab" and "AB"

vi test.log
---------------
abc
CAB
ddabccAB



/[A,a][B,b]
--------------------------------------
Is any conveient way to get ab and AB in vi ?
Due to [A,a[B,b] is typing take a long time.

Sorry, as far as I know, the way you're already using it is the only way to perform such a search in vi (or ed)

One thing you could do is to create a new file as below;

cat FILE | tr '[:upper:]' '[:lower:]' > NEW_FILE

This converts all text in the file into lower case, meaning that you only then have to use /ab in vi to search.

Use the following : command

:ic (ignore case)

and then search with / or ?.

vi test.log

Press Esc then

:set ic

or

:set ignorecase

then search as per your needs.

Hi

As Sanjay suri says, we can ignore the case while searching using / in vi
