try on your machine

This command is using the mailx utility to send an email with a specified subject, recipient, and content.

Let's break down the command:

mailx refers to the mailx utility, which is a command-line email client for sending and receiving emails.
-s "${subject}" sets the subject of the email to the value of the subject variable. The subject should be enclosed in double quotes "".
${to_addr} represents the recipient's email address. It could be another variable or a literal email address.
< symbol redirects the input for the mailx command. It specifies that the content of the email will be taken from the file specified after it.
${content-txt} is the filename or path of the file containing the email content in text format. It could also be another variable or a literal filename.

In summary, this command uses mailx to send an email with a specific subject, recipient, and content read from a plain text file. Make sure to replace ${subject}, ${to_addr}, and ${content-txt} with actual values or variables in your execution context.
