| .SH DESCRIPTION | |||||
| .I Cowsay | |||||
| generates an ASCII picture of a cow saying something provided by the | |||||
| user. If run with no arguments, it accepts standard input, word-wraps | |||||
| the message given at about 40 columns, and prints the cow saying the | |||||
| given message on standard output. | |||||
| .PP | |||||
| To aid in the use of arbitrary messages with arbitrary whitespace, | |||||
| use the | |||||
| .B \-n | |||||
| option. If it is specified, the given message will not be | |||||
| word-wrapped. This is possibly useful if you want to make the cow | |||||
| think or speak in figlet(6). If | |||||
| .B \-n | |||||
| is specified, there must not be any command-line arguments left | |||||
| after all the switches have been processed. | |||||
| .PP | |||||
| The | |||||
| .B \-W | |||||
| specifies roughly (where the message should be wrapped. The default | |||||
| is equivalent to | |||||
| .B \-W 40 | |||||
| i.e. wrap words at or before the 40th column. | |||||
| .PP | |||||
| If any command-line arguments are left over after all switches have | |||||
| been processed, they become the cow's message. The program will not | |||||
| accept standard input for a message in this case. | |||||
| .PP | |||||
| There are several provided modes which change the appearance of the | |||||
| cow depending on its particular emotional/physical state. The | |||||
| .B \-b | |||||
| option initiates Borg mode; | |||||
| .B \-d | |||||
| causes the cow to appear dead; | |||||
| .B \-g | |||||
| invokes greedy mode; | |||||
| .B \-p | |||||
| causes a state of paranoia to come over the cow; | |||||
| .B \-s | |||||
| makes the cow appear thoroughly stoned; | |||||
| .B \-t | |||||
| yields a tired cow; | |||||
| .B \-w | |||||
| is somewhat the opposite of | |||||
| .BR \-t , | |||||
| and initiates wired mode; | |||||
| .B \-y | |||||
| brings on the cow's youthful appearance. | |||||
| .PP | |||||
| The user may specify the | |||||
| .B \-e | |||||
| option to select the appearance of the cow's eyes, in which case | |||||
| the first two characters of the argument string | |||||
| .I eye_string | |||||
| will be used. The default eyes are 'oo'. The tongue is similarly | |||||
| configurable through | |||||
| .B \-T | |||||
| and | |||||
| .IR tongue_string ; | |||||
| it must be two characters and does not appear by default. However, | |||||
| it does appear in the 'dead' and 'stoned' modes. Any configuration | |||||
| done by | |||||
| .B \-e | |||||
| and | |||||
| .B \-T | |||||
| will be lost if one of the provided modes is used. | |||||
| .PP | |||||
| The | |||||
| .B \-f | |||||
| option specifies a particular cow picture file (``cowfile'') to | |||||
| use. If the cowfile spec contains '/' then it will be interpreted | |||||
| as a path relative to the current directory. Otherwise, cowsay | |||||
| will search the path specified in the | |||||
| .B COWPATH | |||||
| environment variable. | |||||
| To list all cowfiles on the current | |||||
| .BR COWPATH , | |||||
| invoke | |||||
| .B \*(nm | |||||
| with the | |||||
| .B \-l | |||||
| switch. | |||||
| .PP | |||||
| If the program is invoked as | |||||
| .B cowthink | |||||
| then the cow will think its message instead of saying it. | |||||
| .PP | |||||
| .SH COWFILE FORMAT | |||||
| A cowfile is made up of a simple block of | |||||
| .BR perl (1) | |||||
| code, which assigns a picture of a cow to the variable | |||||
| .BR $the_cow . | |||||
| Should you wish to customize the eyes or the tongue of the cow, | |||||
| then the variables | |||||
| .B $eyes | |||||
| and | |||||
| .B $tongue | |||||
| may be used. The trail leading up to the cow's message balloon is | |||||
| composed of the character(s) in the | |||||
| .B $thoughts | |||||
| variable. Any backslashes must be reduplicated to prevent | |||||
| interpolation. The name of a cowfile should end with | |||||
| .BR .cow , | |||||
| otherwise it is assumed not to be a cowfile. Also, at-signs (``@'') | |||||
| must be backslashed because that is what Perl 5 expects. | |||||
| .PP | |||||
| .SH COMPATIBILITY WITH OLDER VERSIONS | |||||
| .PP | |||||
| What older versions? :-) | |||||
| .PP | |||||
| Version 3.x is fully backward-compatible with 2.x versions. If | |||||
| you're still using a 1.x version, consider upgrading. And tell me | |||||
| where you got the older versions, since I didn't exactly put them | |||||
| up for world-wide access. | |||||
| .PP | |||||
| Oh, just so you know, this manual page documents version \*(Vn of | |||||
| cowsay. | |||||
| .SH ENVIRONMENT | |||||
| The COWPATH environment variable, if present, will be used to search | |||||
| for cowfiles. It contains a colon-separated list of directories, | |||||
| much like | |||||
| .B PATH or | |||||
| .BR MANPATH . | |||||
| It should always contain the | |||||
| .B /usr/local/share/cows | |||||
| directory, or at least a directory with a file called | |||||
| .B default.cow | |||||
| in it. | |||||
| .SH FILES | |||||
| .B %PREFIX%/share/cows | |||||
| holds a sample set of cowfiles. If your | |||||
| .B COWPATH | |||||
| is not explicitly set, it automatically contains this directory. | |||||
