I have the following command:
wash -n <groups> <<EOF
echo hi
echo bye <<BYE
<commands>
exit 0
BYE
exit 0
EOF
<commands>
where <groups>
are some groups and <commands>
are commands. I don't understand what <<EOF
and <<BYE
mean? Is it some label which the script jumps in case fails? What does this script do?
stdin
alongside the command in a script.
