- glob ?switches? pattern ?pattern ...?
-
-
- DESCRIPTION
- This command performs file name ``globbing'' in a fashion
- similar to the csh shell. It returns a list of the files
- whose names match any of the pattern arguments.
-
- If the initial arguments to glob start with - then they are
- treated as switches. The following switches are currently
- supported:
-
- -nocomplain Allows an empty list to be returned without
- error; without this switch an error is
- returned if the result list would be empty.
-
- -- Marks the end of switches. The argument fol-
- lowing this one will be treated as a pattern
- even if it starts with a -.
-
- The pattern arguments may contain any of the following spe-
- cial characters:
-
- ? Matches any single character.
-
- * Matches any sequence of zero or more characters.
-
- [chars] Matches any single character in chars. If chars
- contains a sequence of the form a-b then any char-
- acter between a and b (inclusive) will match.
-
- \x Matches the character x.
-
- {a,b,...} Matches any of the strings a, b, etc.
-
- As with csh, a ``.'' at the beginning of a file's name or
- just after a ``/'' must be matched explicitly or with a {}
- construct. In addition, all ``/'' characters must be
- matched explicitly.
-
- If the first character in a pattern is ``~'' then it refers
- to the home directory for the user whose name follows the
- ``~''. If the ``~'' is followed immediately by ``/'' then
- the value of the HOME environment variable is used.
-
- The glob command differs from csh globbing in two ways.
- First, it does not sort its result list (use the lsort com-
- mand if you want the list sorted). Second, glob only
- returns the names of files that actually exist; in csh no
- check for existence is made unless a pattern contains a ?,
- *, or [] construct.
