Silence stdout for an entire shell script
Posted: 2010-03-22
To silence stdout
in a Linux shell script use the following line:
exec 1>/dev/null
This redirects the file stream to the /dev/null
device, which silently swallows the output.
This is useful if for instance you are writing a cron job which you want to have log it’s steps while you are developing or debugging it, but don’t want any output except the stderr
once it’s running.
