| acosta@clima$  ping -c1 $ip | grep time= | rev | cut -d" " -f2 | rev |
| cut -d"=" -f2
|
| 0.548

Isso traz um problema:

$ if [ 0.548 -gt 120 ] ; then echo ok ; fi
bash: [: 0.548: integer expression expected

Bash faz operações com inteiros. Eu gosto de trabalhar com awk nesses casos:


$ x=0.548; y=120; echo "$x $y" | awk '{if ($1 > $2) print $1; else print
$2}'
120
