simple shell program to launch pager (most for now) only if input datas won't fit into screen

pager.sh

#!/bin/bash
pgr="most"
tmpFile="/tmp/pager_$(uuidgen)"
cat - /dev/stdin > $tmpFile;
nblines=$(wc -l $tmpFile |awk '{print($1)}');

if [ "$nblines" -gt "$(tput lines)" ]; then
	$pgr $tmpFile
else
	cat $tmpFile && echo ""
fi
rm $tmpFile;
