Sample text

Sometimes it is not obvious which directory a program would be in. While the idiomatic solution is to use which file to find a copy of a file in your execution path, this doesn’t help if you’ve forgotten the exact name of the utility. The glob pattern /usr/*bin/*stat matches any file in either /usr/bin or /usr/sbin with a name ending in stat. When expanding each component, the shell makes a list of possible matches, then compares all of these to the next component. If one of the components never ends up producing any matches, it is discarded completely.

These classes may be combined with other characters; [[:digit:][:alpha:]_] matches any letter or number or an underscore (_). ] to match a special collating symbol. ) These rules are particularly useful for internationalized scripts but not sufficiently widely available to be used in portable scripts yet. ), equals sign (=), or colon (:) in a character class. ] matches a period. ) Character classes are, as you can see, substantially more complicated than the rest of the shell pattern matching rules.

To search in directories with a pattern, you must explicitly include any path separators you wish to match. If a path starts with a path separator, the path is called an absolute path. Otherwise, it is called a relative path. A relative path name is always interpreted relative to your current directory. In fact, even a file name with no separators is technically a relative path; it is just a very short relative path. The decision to match only within specified directories may seem surprising, but it makes good sense.
