I need my script to send an email from terminal. Based on what I've seen here and many other places online, I formatted it like this:
/var/mail -s "$SUBJECT" "$EMAIL" << EOF Here's a line of my message! And here's another line! Last line of the message here! EOF However, when I run this I get this warning:
myfile.sh: line x: warning: here-document at line y delimited by end-of-file (wanted 'EOF') myfile.sh: line x+1: syntax error: unexpected end of file ...where line x is the last written line of code in the program, and line y is the line with /var/mail in it. I've tried replacing EOF with other things (ENDOFMESSAGE, FINISH, etc.) but to no avail. Nearly everything I've found online has it done this way, and I'm really new at bash so I'm having a hard time figuring it out on my own. Could anyone offer any help?

An Unexpected end of file error in a Bash script usually occurs when you there is a mismatched structure somewhere in the script. If you forget to close your quotes, or you forget to terminate an if statement, while loop, etc, then you will run into the error when you try to execute your Bash script.
This operator stands for the end of the file. This means that wherever a compiler or an interpreter encounters this operator, it will receive an indication that the file it was reading has ended. Similarly, in bash, the EOF operator is used to specify the end of the file.
The EOF token must be at the beginning of the line, you can't indent it along with the block of code it goes with.
If you write <<-EOF you may indent it, but it must be indented with Tab characters, not spaces. So it still might not end up even with the block of code.
Also make sure you have no whitespace after the EOF token on the line.
