**Secho** was inspired by a post to the [Plan 9][] mailing list,

where, after a round of bashing on the Unix implementation of [`echo`][echo],

the discussion went to bashing a hypothetical FSF-style implementation of `echo`

and eventually to:

> > ##NAME##

> > 

> > echo: echo arguments

> > 

> > ##SYNOPSIS##

> > 	

> > echo [-1abCDEeilmNnOqrtuVvwXx] [-B base] [-c cmd] [-d char] [-f file] [-L len] [-o file] [-S voice] [-s char] [args...]

> > 

> > ##DESCRIPTION##

> > 	

> > echo outputs its arguments. It takes the following switches:

> > 

> > =-1=

> >     One argument per line.

> > =-a=

> >     Output in ASCII. The default.

> > =-B base=

> >     Output in given base, 2..32. Unless `-u` also given, base > 10 shows lowercase.

> > =-b=

> >     Output in binary.

> > =-C=

> >     Don't echo anything, just print the number of fields.

> > =-c cmd=

> >     Run cmd on each argument, replacing `$?` with the argument itself.

> > =-D=

> >     Output in decimal.

> > =-d char=

> >     Field delimiter. Default is end of argument.

> > =-E=

> >     Print to standard error instead of to standard output.

> > =-e=

> >     Allow escape sequences

> > =-f file=

> >     Read from file, then from command line (if any).

> > =-i=

> >     Read arguments from standard input.

> > =-L len=

> >     Line width set to len. Default is to ignore line lengths.

> > =-l=

> >     Turn uppercase to lowercase.

> > =-m=

> >     Multi-column output.

> > =-N=

> >     One field per line, numbering each field.

> > =-n=

> >     Suppress newline.

> > =-O=

> >     Output in octal.

> > =-o file=

> >     Write to file instead of standard output.

> > =-q=

> >     "Quiet mode:" redirect output to `/dev/null` if not to a file.

> > =-r=

> >     Print every string that matches each regular expression. Regular expressions cannot contain `+` or `*` modifiers.

> > =-S voice=

> >     Send to speaker, having the given voice say it. If voice is a null string, use the default voice.

> > =-s char=

> >     Separate fields with char, default space.

> > =-t=

> >     Separate fields with tabs.

> > =-u=

> >     Convert lowercase to uppercase. With `-B`, output in uppercase letters for base > 10.

> > =-V=

> >     Strip non-printing characters.

> > =-v=

> >     Make non-printing characters visible.

> > =-w=

> >     If `-L` is given, word wrap instead of character wrap. Otherwise, ignored.

> > =-X=

> >     Output in uppercase hexadecimal.

> > =-x=

> >     Output in lowercase hexadecimal.

> 

> Test for everyone: write this echo in as little code as possible. C or rc is permitted. The rules:

> 

> - for C: either Standard C (no other libraries) or only libc (no other Plan 9 libraries)

> - for rc: only use programs in the core Plan 9 distribution - no programs that I have to get myself

> - match the behavior EXACTLY as above

> - shortest code and fastest run time wins

> 

> Winner gets something cool.
