Cu programul read_data citesc datele din "data". Problema este ca nu pot
sa-l fac sa ignore liniile goale. Ce gresesc?
"data" file
3 1444
4 1445
5 1446
<aici e endline>
<aici e endline>
<aici e endline>
"read_data" file
#!/bin/bash
cat data | while read line
do
set -- $line
# $1=ip-ul, $2=portul
if [ -n `echo $1 | tr -d '[:space:]'` ]; then
echo ip=192.168.0.$1 port=$2
fi
done
OUTPUT:
ip=192.168.0.3 port=1444
ip=192.168.0.4 port=1445
ip=192.168.0.5 port=1446
ip=192.168.0. port=
ip=192.168.0. port=
ip=192.168.0. port=
ip=192.168.0. port=
ip=192.168.0. port=
ip=192.168.0. port=
