Bytes and lines +are numbered starting with 1. If any given file is compressed, its +decompressed content is used. Compressed files are decompressed on the +fly; no temporary files are created. +.PP +The formats supported are bzip2, gzip, lzip and xz. +.PP +Zcmp compares file1 to file2. If file2 is omitted zcmp 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. +.SH OPTIONS +.TP +\fB\-h\fR, \fB\-\-help\fR +display this help and exit +.TP +\fB\-V\fR, \fB\-\-version\fR +output version information and exit +.TP +\fB\-b\fR, \fB\-\-print\-bytes\fR +print differing bytes +.TP +\fB\-i\fR, \fB\-\-ignore\-initial=\fR<n>[:<n2>] +ignore differences in the first <n> bytes +.TP +\fB\-l\fR, \fB\-\-list\fR +list position, value of all differing bytes +.TP +\fB\-M\fR, \fB\-\-format=\fR<list> +process only the formats in <list> +.TP +\fB\-n\fR, \fB\-\-bytes=\fR<n> +compare at most <n> bytes +.TP +\fB\-N\fR, \fB\-\-no\-rcfile\fR +don't read runtime configuration file +.TP +\fB\-O\fR, \fB\-\-force\-format\fR=\fI\,[\/\fR<f1>][,<f2>] +force given formats (bz2, gz, lz, xz) +.TP +\fB\-q\fR, \fB\-\-quiet\fR +suppress all messages +.TP +\fB\-s\fR, \fB\-\-silent\fR +(same as \fB\-\-quiet\fR) +.TP +\fB\-v\fR, \fB\-\-verbose\fR +verbose mode (same as \fB\-\-list\fR) +.TP +\fB\-\-bz2=\fR<command> +set compressor and options for bzip2 format +.TP +\fB\-\-gz=\fR<command> +set compressor and options for gzip format +.TP +\fB\-\-lz=\fR<command> +set compressor and options for lzip format +.TP +\fB\-\-xz=\fR<command> +set compressor and options for xz format +.PP +Numbers may be followed by a multiplier: k = kB = 10^3 = 1000, +Ki = KiB = 2^10 = 1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc... +.SH "REPORTING BUGS" +Report bugs to zutils\-bug@nongnu.org +.br +Zutils home page: http://www.nongnu.org/zutils/zutils.html +.SH COPYRIGHT +Copyright \(co 2019 Antonio Diaz Diaz. +License GPLv2+: GNU GPL version 2 or later <http://gnu.org/licenses/gpl.html> +.br +This is free software: you are free to change and redistribute it. +There is NO WARRANTY, to the extent permitted by law. |
