+.TH ZDIFF "1" "January 2019" "zdiff (zutils) 1.8" "User Commands"
+.SH NAME
+zdiff \- decompress and compare two files line by line
+.SH SYNOPSIS
+.B zdiff
+[\fI\,options\/\fR] \fI\,file1 \/\fR[\fI\,file2\/\fR]
+.SH DESCRIPTION
+Zdiff compares two files ('\-' means standard input), and if they
+differ, shows the differences line by line. If any given file is
+compressed, its decompressed content is used. Zdiff is a front end to
+the diff program and has the limitation that messages from diff refer to
+temporary filenames instead of those specified.
+.PP
+The formats supported are bzip2, gzip, lzip and xz.
+.PP
+Zdiff compares file1 to file2. If file2 is omitted zdiff tries the
+following:
+.IP
+1. If file1 is compressed, compares its decompressed contents with
+the corresponding uncompressed file (the name of file1 with the
+extension removed).
+.IP
+2. If file1 is uncompressed, compares it with the decompressed
+contents of file1.[lz|bz2|gz|xz] (the first one that is found).
+.IP
+3. If no suitable file is found, compares file1 with data read from
+standard input.
+.PP
+Exit status is 0 if inputs are identical, 1 if different, 2 if trouble.
