NAME
  lsearch - See if a list contains a particular element

SYNOPSIS
  lsearch ?mode? list pattern

DESCRIPTION
  This command searches the elements of list to see if one of them matches
  pattern. If so, the command returns the index of the first matching
  element. If not, the command returns -1. The mode argument indicates how
  the elements of the list are to be matched against pattern and it must
  have one of the following values:

  -exact
    The list element must contain exactly the same string as pattern. 

  -glob
    Pattern is a glob-style pattern which is matched against each list
    element using the same rules as the string match command.

  -regexp
    Pattern is treated as a regular expression and matched against each list
    element using the same rules as the regexp command.

  If mode is omitted then it defaults to -glob.  

EXAMPLE
  % set x {ABC DEF {GHI JKL} MNO}
  ABC DEF {GHI JKL} MNO

  % lsearch $x G*
  2

  % lsearch $x MNO
  3

  % lsearch -glob $x D*
  1

  % lsearch -exact $x ABC
  0

  % lsearch -exact $x mno
  -1
