You can use mailx command for this purpose as example below

mailx -s &quot;Testing mailx commond&quot; surachal@dtac.co.th <<-EOF
Hello world

EOF

Actually, you should be able to do the same with mail (instead of using mailx):

mail -s &quot;Shell Generated Mail&quot; steview85 <<-EOF
Hello world
EOF

Note that &quot;EOF&quot; stands for &quot;end of file&quot;, but it is just a label here -- you can use another label if you prefer. The script reads as input (<<) until it hits the label indicated by the - and then passes a ctl-d (which is the true end of file - just like you do when you use the mail program interactively).

I don't know what you're trying to do, but knowing that ctl-d is the EOF mark gives you other options. You could write the content out to a file and then send that. Here's an example that demonstrates some possibilities:

rm -f mtmpfile
cat <<-EOF > mtmpfile
hello world
EOF
...
command >> mtmpfile
...
mail -s &quot;Mail from file&quot; steview85 < mtmpfile
rm -f mtmpfile

(Of course, you need to ensure you have permission to write to mtmpfile.)
