Hi,
I could not get the pr command to fold the lines. Is this a bug?
I am using pr (GNU coreutils) 8.13 under GNU bash 4.2.24.
Here is an example - the following pr command produced an output that
instead of folding a long line of text in the first column, it cuts it off:
$ echo "Snow with areas of blowing snow. Low around 24. East wind around
15 mph, with gusts as high as 25 mph. Chance of precipitation is 100%.
Total nighttime snow accumulation of 2 to 4 inches possible." | pr -F
--columns=2

Snow with areas of blowing snow. L
fold or fmt are used to wrap text.
It can then be passed on to pr for
further layout and truncation:
You can paste this command to a terminal for illustration:
for i in $(seq 22); do
clear
seq -f '%03.f' 1 $i |
fmt -w20 |
pr -t -c2 -w40 -s'|'
sleep 1
done
thanks,
Pádraig.
