Indeed, in the later case, file descriptor 2 is set to the current address of file descriptor ``1 (which is stdout at this very moment), and then the file descriptor 1 is redirected to /dev/null. Try these two commands with a non-privileged user: ls >/dev/null 2>&1 Warning: the order of redirection matters: >/dev/null 2>&1
As such, no output is produced and no mail is sent. Is redirecting the error stream to the output stream, which has been redirected to /dev/null. stdout) and file descriptor 2 is standard error (a.k.a. & is the address operator as in the C language.Ĭonventionally, file descriptor 1 is standard output (a.k.a.

Now to the syntax: this is specific to the Bourne shell language (and its derivatives such as bash, zsh, and so on). So what your article suggests here is to produce no output, thus sending no mail.Īnother way (more convenient?) to disable mail is to use the -m off option, i.e. When executing commands, any output is mailed to the owner of the crontab. It should be: x * * * * /path/to/my/script > /dev/null 2>&1 In other words, the script is silenced.īy the way, you need to have a > in front of /dev/null 2>&1. Since STDERR is now going to STDOUT (because of 2>&1) both STDERR and STDOUT ends up in the blackhole /dev/null. Now we already have > /dev/null at the end of the script which means all the standard output ( STDOUT) will be written to /dev/null. to treat all the error messages generated from the script as its standard output). 1 is the handle for standard output or STDOUTĢ>&1 is asking to direct all the STDERR as STDOUT, (ie.2 is the handle for standard error or STDERR.When you run a script that gives you an output and if we add a > /dev/null 2>&1 at the end of the script, we are asking the script to write whatever that is generated from the script (both the output and error messages) to /dev/null. Whatever that is written to it, get discarded or disappears. dev/null is a device file that acts like a blackhole.
