+.TH ZGREP "1" "January 2019" "zgrep (zutils) 1.8" "User Commands"
+.SH NAME
+zgrep \- search compressed files for a regular expression
+.SH SYNOPSIS
+.B zgrep
+[\fI\,options\/\fR] \fI\,<pattern> \/\fR[\fI\,files\/\fR]
+.SH DESCRIPTION
+Zgrep is a front end to the grep program that allows transparent search
+on any combination of compressed and uncompressed files. If any given
+file is compressed, its decompressed content is used. If a given file
+does not exist, and its name does not end with one of the known
+extensions, zgrep tries the compressed file names corresponding to the
+formats supported.
+.PP
+If a file is specified as '\-', data are 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 in the same
+compression format.
+.PP
+If no files are specified, recursive searches examine the current
+working directory, and nonrecursive searches read standard input.
+.PP
+The formats supported are bzip2, gzip, lzip and xz.
+.PP
+Exit status is 0 if match, 1 if no match, 2 if trouble.
