XZGREP(1) XZ Utils XZGREP(1)NAME
xzgrep - search compressed files for a regular expression
SYNOPSIS
xzgrep [grep_options] [-e] pattern file...
xzegrep ...
xzfgrep ...
lzgrep ...
lzegrep ...
lzfgrep ...
DESCRIPTION
xzgrep invokes grep(1) on files which may be either uncompressed or compressed with xz(1), lzma(1), gzip(1), or bzip2(1). All options
specified are passed directly to grep(1).
If no file is specified, then the standard input is decompressed if necessary and fed to grep(1). When reading from standard input,
gzip(1) and bzip2(1) compressed files are not supported.
If xzgrep is invoked as xzegrep or xzfgrep then egrep(1) or fgrep(1) is used instead of grep(1). The same applies to names lzgrep, lze-
grep, and lzfgrep, which are provided for backward compatibility with LZMA Utils.
ENVIRONMENT
GREP If the GREP environment variable is set, xzgrep uses it instead of grep(1), egrep(1), or fgrep(1).

DGREP(1) Debian-goodies documentation DGREP(1)NAME
dgrep, degrep, dfgrep, dzgrep -- grep through files belonging to an installed Debian package
SYNOPSIS
dgrep [most grep options] pattern package...
dgrep --help
DESCRIPTION
dgrep invokes grep(1) on each file in one or more installed Debian packages.
It passes the package argument(s) to dglob(1) to retrieve a list of files in those packages. You can use POSIX regular expressions for the
package names.
If dgrep is invoked as degrep, dfgrep or dzgrep then egrep(1), fgrep(1) or zgrep(1) is used instead of grep.
OPTIONS
dgrep supports most of grep(1)'s options. Please refer to your grep 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.
Options of grep that are not supported by dgrep
-r, --recursive, -d recurse, --directories=recurse
-d read, --directories=read
dgrep searches only in the "normal" files of a package. It skips all directories and symlinks. Therefor the options of grep that are
specific to directories are not supported.
