check index of a string by finding a letter in it

i would like to search for a letter in a string and get its index position.
example:
Code:
name='john'

pos=$(expr index $name o)

the result will be equal to 2 (2nd position)

how do you make this thing not case sensitive?
example:
Code:
name='john'

pos=$(expr index $name O)

the capitalization is the issue.

ZIP_GET_NAME(3) 					     Library Functions Manual						   ZIP_GET_NAME(3)

NAME
zip_get_name - get name of file by index LIBRARY
libzip (-lzip) SYNOPSIS
#include <zip.h> const char * zip_get_name(struct zip *archive, int index, int flags); DESCRIPTION
The zip_get_name function returns the name of the file at position index in archive. If flags is set to ZIP_FL_UNCHANGED, the original unchanged filename is returned. The returned string must not be modified or freed, and becomes invalid when archive is closed. RETURN VALUES
Upon successful completion, a pointer to the name is returned. Otherwise, NULL and the error code in archive is set to indicate the error. ERRORS
zip_get_name fails if: [ZIP_ER_DELETED] index refers to a file that has been deleted (see zip_delete(3) ). [ZIP_ER_INVAL] index is not a valid file index in archive, or index points to an added file and ZIP_FL_UNCHANGED is set. SEE ALSO
