[previous article] [next article]If you have two files that you want to merge by columns there is a UNIX program called paste A simple example of this is:
Script started on Wed Nov 7 16:14:55 1990
% cat x
1
2
3
% cat y
10.
20.
30.
% paste x y
1 10.0
2 20.0
3 30.0
Note: This column merging is on the screen; so, to save the
information into a file, use:
% paste x y > xy
Now you have a file called xy that can be read by grap! Also,
the tbl program can be easily used to print the file. If you are
putting columns of data together for another program, you may
need to remove the separation character that is used by paste You
can see with the cat -t command that the tab key separates the
two columns:
% cat -t xy
1^I10.0
2^I20.0
3^I30.0
%
The "expand" command can be used to create a file with NO tab
characters...
% expand < xy > xy.good
% cat -t xy.good
1 10.0
2 20.0
3 30.0
