Full Discussion: Ignore the 255 character limit of command line

Just to make this clear:

There's no way to "ignore" argument length limits or argument size problems. That's a system limitation. 255 characters is an unusually severe limit, but there's always a limit. No shell syntax is ever going to fit a 10-foot truck under an 8-foot tunnel.

I've seen people pile on more and more braces, backticks, and eval until the shell stops saying "too many arguments" but it's still a 10-foot truck and 8-foot tunnel. If you made it fit, you must have wrecked the truck.

If it won't fit as an argument, you have to pass it by other means, like a file.

man

MAN(7)							 Miscellaneous Information Manual						    MAN(7)

NAME

       man - macros to typeset manual

SYNOPSIS

       nroff  -man  file ...

       troff  -man  file ...

DESCRIPTION

       These macros are used to lay out pages of this manual.  A skeleton page may be found in the file /usr/man/man0/xx.

       Any  text  argument t may be zero to six words.	Quotes may be used to include blanks in a `word'.  If text is empty, the special treatment
       is applied to the next input line with text to be printed.  In this way .I may be used to italicize a whole line, or .SM followed by .B	to
       make small bold letters.

       A  prevailing  indent  distance	is  remembered	between successive indented paragraphs, and is reset to default value upon reaching a non-
       indented paragraph.  Default units for indents i are ens.

       Type font and size are reset to default values before each paragraph, and after processing font and size setting macros.

       These strings are predefined by -man:

       *R    `(Reg)', trademark symbol in troff.

       *S    Change to default type size.

FILES

       /usr/lib/tmac/tmac.an
       /usr/man/man0/xx

SEE ALSO

       troff(1), man(1)

BUGS

       Relative indents don't nest.
