By default, lsearch uses the "globbing" method of finding a match.  Globbing is the wildcarding technique that most Unix shells use.

'''globbing''' wildcards are:

   '''*''':    Matches any quantity of any character

   '''?''':    Matches one occurrence of any character

   '''\X''':    The backslash escapes a special character in globbing just the way it does in Tcl substitutions.  Using the backslash lets you use glob to match a `*` or `?`.

   '''[[...]]''':    Matches one occurrence of any character within the brackets. A range of characters can be matched by using a range between the brackets.  For example, [[a-z]] will match any lower case letter.


There is also a `glob` command that you will see in later sections that uses glob pattern matching in directories, and returns a list of the matching files.

***Example***

======
# Matches
string match f* foo

# Matches
string match f?? foo

# Doesn't match
string match f foo

# Returns a big list of files on my Debian system.
set bins [glob /usr/bin/*]
======
