longDescription = ''
|
||
|
rs reads the standard input, interpreting each line as a row of blank-
|
||
|
separated entries in an array, transforms the array according to the op-
|
||
|
tions, and writes it on the standard output. With no arguments (argc < 2)
|
||
|
it transforms stream input into a columnar format convenient for terminal
|
||
|
viewing, i.e. if the length (in bytes!) of the first line is smaller than
|
||
|
the display width, -et is implied, -t otherwise.
|
||
|
|
||
|
The shape of the input array is deduced from the number of lines and the
|
||
|
number of columns on the first line. If that shape is inconvenient, a more
|
||
|
useful one might be obtained by skipping some of the input with the -k
|
||
|
option. Other options control interpretation of the input columns.
|
||
|
|
||
|
The shape of the output array is influenced by the rows and cols specifi-
|
||
|
cations, which should be positive integers. If only one of them is a po-
|
||
|
sitive integer, rs computes a value for the other which will accommodate
|
||
|
all of the data. When necessary, missing data are supplied in a manner
|
||
|
specified by the options and surplus data are deleted. There are options
|
||
|
to control presentation of the output columns, including transposition of
|
||
|
the rows and columns.
