dog - better than cat


dog [-AbBeEnstTuv] [-w[cols]] [-l lines] [--show-all] [--number-nonblank] [--no-blanks] [--bind=port] [--dos] [--show-ends] [--hang-up] [--images] [--links] [--lower] [--mac] [--number] [--no-header] [--squeeze-blank] [--sock=domain:port] [--sock-test] [--show-tabs] [--raw] [--rot=num] [--udp] [--unix] [--upper] [--show-nonprinting] [--hide-nonprinting] [--help] [--hex] [--skip-tags] [--version] file | URL | - ...


dog writes the contents of each given file, URL, or the standard input if none are given or when a file named '-' is given, to the standard output. It currently supports the file, http, and raw URL types. It is designed as a compatible, but enhanced, replacement of cat(1).


-A, --show-all
Equivalent to -vET
-b, --number-nonblank
Number all nonblank output lines, starting with 1.
Equivalent to -vE
-E, --show-ends
Display a `$' at the end of each line.
-n, --number
Number all output lines, starting with 1.
-s, --squeeze-blank
Replace multiple adjacent blank lines with a single blank line.
Equivalent to -vT
-T, --show-tabs
Display TAB characters as `^I'.
Ignored; for Unix compatibility.
Print first n characters of each line (default=80)
-v, --show-nonprinting
Display control characters except for LFD and TAB using `^' notation and precede characters that have the high bit set with `M-'.
Strip nonprinting characters when printing to output.
-B, --no-blanks
Only print lines that contain at least one non-whitespace character.
Use UDP instead of TCP with sockets.
Connection, dump input data to remote port, and print response.
With --sock , test whether port is available or not, and print result.
Bind to a port, dump input data to connecting client, and print all incoming data from client. --hang-up will cause dog to exit after dumping input data to connecting client, not waiting for multiple clients or printing data from clients. --no-header will cause dog to not display info on each connection.
Do not wait for socket input during --bind
Do not display header on HTTP data. In conjunction with --bind , do not display info on each connection.
Treats input as HTML and lists unique, absolute image links from input data.
Treats input as HTML and lists unique, absolute URL links from input data.
Skips tags for formatting options. Tags are still included in output, but only non-tag data will be affected by the various formatting options.
Convert all lower-case characters to upper-case.
Convert all upper-case characters to lower-case.
Convert DOS, MAC, and UNIX line endings to style specified by --dos , --mac , or --unix . Dog will default to the style of the operating system that it is running under.
--dos, --mac --unix
Respectively convert line endings to DOS-style, MAC-style, and UNIX-style. Use in conjunction with --translate to convert from DOS, MAC, or UNIX line ending styles between each other.
-l  lines
Specify list of lines to print, with ranges, comma delimited. All of the ranges are inclusive. For example, to display lines 5, 7 through 10, 25, 32 through 50, and 72 through 300, you would use the argument "-l 5,7-10,25,32-50,72-300". If you wanted to print all lines up to 10 (inclusive), you would use the argument "-l -10". Finally, if you would like to print all lines after line 50, you would use the argument "-l 50-".
Rotate character values (can be negative).
Print a usage message and exit.
Dump the input data as a hex dump. Other formatting flags will not apply.
Print version information on standard output, then exit.
