For case-insensitive string search  use index  or rindex  in combination with fc  This example expands on the answer by Eugene Yarmash  use feature qw  fc     my  str    quot Abc quot    my  substr    quot aB quot     print  quot found quot  if index  fc  str  fc  substr      -1    Prints  found  print  quot found quot  if rindex  fc  str  fc  substr      -1    Prints  found   str    quot Abc quot    substr    quot bA quot    print  quot found quot  if index  fc  str  fc  substr      -1    Prints nothing  print  quot found quot  if rindex  fc  str  fc  substr      -1    Prints nothing  Both index and rindex return -1 if the substring is not found  And fc returns a casefolded version of its string argument  and should be used here instead of the  more familiar  uc or lc  Remember to enable this function  for example with use feature qw  fc

If you just need to search for one string within another  use the index function  or rindex if you want to start scanning from the end of the string    if  index  string   substring     -1       print    string  contains   substring  n       To search a string for a pattern match  use the match operator m     if   string    m pattern         print    string  matches the pattern n
