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

I think 'pr' does the pagination and columnation, but doesn't actual re-folds (=wraps) lines to your desired length. It is 'fmt' that can split long lines and join short lines.
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
2013-02-22 04:08 Page 1
Snow with areas of blowing snow. L
Example with pr and fmt:
$ TEXT="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."
Re-fold into one column of 34 characters
$ echo "$TEXT" | fmt -w 34 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.
Columnate the text
$ echo "$TEXT" | fmt -w 34 | pr -F --columns=2 2013-02-22 14:08 Page 1
Snow with areas of blowing snow. is 100%. Total nighttime snow Low around 24. East wind around accumulation of 2 to 4 inches 15 mph, with gusts as high as possible. 25 mph. Chance of precipitation
Notes:
34 characters was chosen because the default page length of pr is 72 (and you want 2 columns + separator).
"pr -F" doesn't mean "fold", it means "use form-feed to separate pages" - just making sure you intended to use that.
HTH, -gordon

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
