index

NAME

index - find a substring within a string


SYNOPSIS

index STR,SUBSTR,POSITION

index STR,SUBSTR


DESCRIPTION

Returns the position of the first occurrence of SUBSTR in STR at or after POSITION. If POSITION is omitted, starts searching from the beginning of the string. The return value is based at 0 (or whatever you've set the $[ variable to--but don't do that). If the substring is not found, returns one less than the base, ordinarily -1.
