====== Logando tudo que o shellscript faz para um arquivo de log ======


<code bash>
#!/bin/bash

LOG_LOCATION=/var/log/scripts/logs
exec > >(tee -i $LOG_LOCATION/MylogFile.log)
exec 2>&1

echo "Log Location should be: [ $LOG_LOCATION ]"
</code>




You can add this line on top of your script:
<code bash>
#!/bin/bash
# redirect stdout/stderr to a file
exec &> logfile.txt
</code>

OR else to redirect only stdout use:
<code bash>
exec > logfile.txt
</code>
