lsearch - See if a list contains a particular element
lsearch ?mode? list pattern
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 rules described in the re_syntax
reference page.
If mode is omitted then it defaults to -glob.
