.IX Title "DGREP 1"
.TH DGREP 1 "2006-07-24" "perl v5.8.8" "Debian-goodies documentation"
.SH "NAME"
dgrep, degrep, dfgrep, dzgrep \-\- grep through files belonging to an installed Debian package
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBdgrep\fR [\fImost grep options\fR] \fIpattern\fR \fIpackage\fR...
.PP
\&\fBdgrep\fR \fB\-\-help\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBdgrep\fR invokes \fIgrep\fR\|(1) on each file in one or more installed Debian 
packages.
.PP
It passes the \fIpackage\fR argument(s) to \fIdglob\fR\|(1) to retrieve a list of files 
in those packages. You can use \s-1POSIX\s0 regular expressions for the package 
names.
.PP
If \fBdgrep\fR is invoked as \fBdegrep\fR, \fBdfgrep\fR or \fBdzgrep\fR then \fIegrep\fR\|(1), 
\&\fIfgrep\fR\|(1) or \fIzgrep\fR\|(1) is used instead of \fBgrep\fR.
.SH "OPTIONS"
.IX Header "OPTIONS"
\&\fBdgrep\fR supports most of \fIgrep\fR\|(1)'s options. Please refer to your 
\&\fBgrep\fR documentation (i.e. the manpage or the texinfo manual) for
a complete listing. Only a few options are excluded because they do not 
conform with the intended behaviour, see the list below.
.Sh "Options of grep that are not supported by dgrep"
.IX Subsection "Options of grep that are not supported by dgrep"
.IP "\fB\-r\fR, \fB\-\-recursive\fR, \fB\-d\fR \fIrecurse\fR, \fB\-\-directories\fR=\fIrecurse\fR" 4

.PD 0
.IP "\fB\-d\fR \fIread\fR, \fB\-\-directories\fR=\fIread\fR" 4
.IX Item "-d read, --directories=read"
.PD
\&\fBdgrep\fR searches only in the \*(L"normal\*(R" files of a package. It skips all
directories and symlinks. Therefor the options of
grep that are specific to directories are not supported.
