how to insert new line in the email using linux mail command?

echo "Hi xxx, would you tell me something?\\n thanks!\\n -xxx" | mail -s "subject" [e-mail]

The email shows the literal '\n', not a newline, how do fix it?

回答1:

Try using echo -e

echo -e "Hello \n World"

You can type man echo from the command line to read more.

With mailx, if you send the email to oultook user, you can add 2 spaces at the begenig of each line.

{ echo "Hi xxx, would you tell me something" ; echo "thanks!" ; echo "-xxx" } | sed 's/^/  /g' | mailx -s "subject" [e-mail]

I encountered this issue and resolved it by surrounding with quotes the variable I was piping into mailx.

I started with a list of processes from ps i.e. list="$(ps |grep some_process)".

Then when I tried to mail that out as follows, the newlines were obliterated:

echo $body | mailx -s "${subject}" [e-mail]

But, simply wrapping $body with quotes preserved the newlines:

echo "$body" | mailx -s "${subject}" [e-mail]

The accepted answer did not work for me when using the mail command, I had to use

\r

My whole command is

mail -s "SUBJECT" -aFrom:"[e-mail] "[e-mail]" <<< $( echo -e "Line1\rLine2")
