Paste's man page contains an example for a reimplementation of
nl(1). This example uses the command line
sed = myfile | paste -s -d '\t\n' - -
in order to concatenate consecutive lines with an intervening tab.
However, the way the example uses the switches -s and -d and two `dash`
input files is redundant. There are in fact two equivalent but simpler
ways to achieve the desired result:
sed = myfile | paste -s -d '\t\n' -
uses the same style as the previous example, while
sed = myfile | paste - -
is arguably even simpler and illustrates the final sentence of the
DESCRIPTION.
