.SH DESCRIPTION
Zgrep \- Grep wrapper for compressed files.
.PP
Zgrep is a wrapper script around the grep command that allows
transparent search on any combination of compressed and non\-compressed
files. If any given file is compressed, its uncompressed content is
used. If a given file does not exist, zgrep tries the compressed file
names corresponding to the supported compressors. If no files are
specified, data is read from standard input, decompressed if needed, and
fed to grep. Data read from standard input must be of the same type; all
uncompressed or all compressed with the same compressor.
The supported compressors are bzip2, gzip, lzip and xz.
.PP
Zegrep is a shortcut for "zgrep \fB\-E\fR"
Zfgrep is a shortcut for "zgrep \fB\-F\fR"
.PP
GREP_OPTIONS are passed directly to grep.
The exit status from grep is preserved.
