Simple pattern matching - "globbing"
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
- 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.
# 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/*]
