The command line switches that select an alternative format correspond to the following format specifiers. The prlong utility formats long amounts of data, folding across multiple lines. It is useful to reformat output of elmalias . Prlong reads data from its standard input, one line at a time, and tries to place as much information as possible on each output line. A field seperator, by default a single space, seperates each input record in the output lines.
Every output line is preceded by a leader field.
By default the leader of the first output line is an empty string, and the leader for all subsequent output lines is a single tab. If an input record exceeds the maximum output line length, it will appear unmodified on an output line all by itself. The following options may be used to modify the prlong behavior. The default is 78 columns. The width calculation assumes that tabstops occur every eight spaces.
