Tengo 10 números de IP que tengo que hacer ping diariamente para verificar, cómo puedo hacer eso usando el script BASH. Para poder automatizar esa tarea usando cron. Solo quiero script BASH.
Gracias.

Respuestas:
Como su rango de ip no tiene simetría y solo hay 10 nodos, sugeriría que los enumere en un archivo de texto. Estoy considerando que el archivo que contiene la lista es el list.txt
que contiene la lista de ip uno en cada línea como se muestra a continuación,
10.12.13.14
172.15.48.3
192.168.45.54
...
48.114.78.227
Puedes usar este script,
#!/bin/bash
# Program name: pingall.sh
date
cat /path/to/list.txt | while read output
do
ping -c 1 "$output" > /dev/null
if [ $? -eq 0 ]; then
echo "node $output is up"
else
echo "node $output is down"
fi
done
Para actualizar el estado de ejecución de sus nodos en un intervalo de 30 minutos, use en crontab,
*/30 * * * * /path/to/pingall.sh > /path/to/log.txt
Salida de log.txt
$ cat /path/to/log.txt

node 10.12.13.14 is up
node 172.15.48.3 is up
node 192.168.45.54 is up
...
node 48.114.78.227 is down
#!/bin/bash
while read hostname
do
ping -c 1 -t 1 "$hostname" > /dev/null 2>&1 &&
echo "Ping Status of $hostname : Success" ||
echo "Ping Status of $hostname : Failed"
done < host.txt
$ cat host.txt
host1.example.com
192.168.0.123
8.8.8.8
...

Revisa este script.
#!/bin/bash
for i in `seq ${2} ${3}`
do
ping -c 1 ${1}.${i} > /dev/null 2>&1
if [ $? -eq 0 ]; then
echo "${1}.${i} responded."
else
echo "${1}.${i} did not respond."
fi
done
Para ejecutar ./script 192.168.1 0 10, por ejemplo, esto comprueba los ips 192.168.1.0 a 192.168.1.10 y echo respondió si ping está bien y no respondió si no.
NB: puede reemplazar $ 1 $ 2 $ 3 por variables estáticas si el rango y las IP son siempre iguales.
Suponga que tiene 5 IP (para reducir solo la respuesta), luego puede hacer ping con
#!/usr/bin/bash
for i in xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxxx
do
ping -c 5 $i
done
Nota: No se incluyen corchetes, sin comas (,) entre las IP.
Espero que ayude.

trabajo, sería necesario un medio para notificar al usuario el resultado del trabajo, o sugiere algo más?
Bien
Tan simple como eso: use el parallel --gnu
comando y luego su comando.
