fpr [ file... ]
In UNIX System V, the asa utility is the standard, not fpr. fpr reads one file and writes another file. It transforms a file formatted by FORTRAN carriage-control conventions into a file formatted by UNIX line-printer conventions. fpr copies its input onto its output, replacing the carriage control characters with characters that will produce the intended effects when printed using lpr. The first character of each line determines the vertical spacing as follows:
one line
two lines
to first line of next page
no advance
A blank line (that is, an empty line) is treated as if its first character is a blank.
A blank line that appears as a carriage control character only is deleted.
A zero is changed to a newline.
A one is changed to a form feed.
A plus is simulated using backspaces.
Given the following file:
write(*,'(" Blank")')
write(*,'("0Zero ")')
write(*,'("+ Plus ")')
write(*,'("1One ")')
end
Example 1 With actual files:
a.out > MyOutputFile fpr < MyOutputFile | lprExample 2 With only pipes:
a.out | fpr | lpr
Both of the above examples produce two pages of output.
Page 1:
Blank
ZeroPlus
Page 2:
One
Results are undefined for input lines longer than 170 characters.
