glob(n) Tcl Built-In Commands glob(n)______________________________________________________________________________NAMEglob - Return names of files that match patterns
SYNOPSISglob ?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 following this
one will be treated as a pattern even if it starts with
a -.
The pattern arguments may contain any of the following special charac‐
ters:
? 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 character 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 command 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.
PORTABILITY ISSUES
Unlike other Tcl commands that will accept both network and native
style names (see the filename manual entry for details on how native
and network names are specified), the glob command only accepts native
names. │
Windows │
For Windows UNC names, the servername and sharename components │
of the path may not contain ?, *, or [] constructs. On Windows │
NT, if pattern is of the form ``~username@domain'' it refers to │
the home directory of the user whose account information resides │
on the specified NT domain server. Otherwise, user account │
information is obtained from the local computer.
