.SH SYNOPSIS
|
|
\fBglob \fR?\fIswitches\fR? \fIpattern \fR?\fIpattern ...\fR?
|
|
.BE
|
|
|
|
.SH DESCRIPTION
|
|
.PP
|
|
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 \fIpattern\fR arguments.
|
|
.LP
|
|
If the initial arguments to \fBglob\fR start with \fB\-\fR then
|
|
.VS
|
|
they are treated as switches. The following switches are
|
|
currently supported:
|
|
.TP 15
|
|
\fB\-nocomplain\fR
|
|
Allows an empty list to be returned without error; without this
|
|
switch an error is returned if the result list would be empty.
|
|
.TP 15
|
|
\fB\-\|\-\fR
|
|
Marks the end of switches. The argument following this one will
|
|
be treated as a \fIpattern\fR even if it starts with a \fB\-\fR.
|
|
.VE
|
|
.PP
|
|
The \fIpattern\fR arguments may contain any of the following
|
|
special characters:
|
|
.TP 10
|
|
\fB?\fR
|
|
Matches any single character.
|
|
.TP 10
|
|
\fB*\fR
|
|
Matches any sequence of zero or more characters.
|
|
.TP 10
|
|
\fB[\fIchars\fB]\fR
|
|
Matches any single character in \fIchars\fR. If \fIchars\fR
|
|
contains a sequence of the form \fIa\fB\-\fIb\fR then any
|
|
character between \fIa\fR and \fIb\fR (inclusive) will match.
|
|
.TP 10
|
|
\fB\e\fIx\fR
|
|
Matches the character \fIx\fR.
|
|
.TP 10
|
|
\fB{\fIa\fB,\fIb\fB,\fI...\fR}
|
|
Matches any of the strings \fIa\fR, \fIb\fR, etc.
|
|
.LP
|
|
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.
|
|
.LP
|
|
If the first character in a \fIpattern\fR 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.
|
|
.LP
|
|
The \fBglob\fR command differs from csh globbing in two ways.
|
|
First, it does not sort its result list (use the \fBlsort\fR
|
|
command if you want the list sorted).
|
|
.VS
|
|
Second, \fBglob\fR only returns the names of files that actually
|
|
exist; in csh no check for existence is made unless a pattern
|
|
contains a ?, *, or [] construct.
|
|
|
|
.SH PORTABILITY ISSUES
|
|
.PP
|
|
Unlike other Tcl commands that will accept both network and native
|
|
style names (see the \fBfilename\fR manual entry for details on how
|
|
native and network names are specified), the \fBglob\fR command only
|
|
accepts native names. Also, for Windows UNC names, the servername and
|
|
sharename components of the path may not contain ?, *, or []
|
|
constructs.
