sed命令无法通过SSH使用

Question

Consider the following command:

ssh MACHINE sed -i 's#\[ "\$JBOSS_MODE" = "standalone" \]#\[ "\$JBOSS_MODE" = "sim_standalone" \]#' /tmp/sim-wildfly

When I run this command from the command line, I get this error:

sed: -e expression #1, char 3: unterminated `s' command

However, when I SSH into that particular machine first, and then run the sed part of the command, it works fine:

> ssh MACHINE
> sed -i 's#\[ "\$JBOSS_MODE" = "standalone" \]#\[ "\$JBOSS_MODE" = "sim_standalone" \]#' /tmp/sim-wildfly

Any idea why this would happen?

EDIT: I believe it has something to do with how I'm escaping characters, because I just tried simple test replacement with no escaped characters and it worked fine. I tried double-escaping, but that didn't work either.

Try ssh with here-doc to avoid crazy escaping:

ssh -t -t MACHINE <<'EOF'
sed -i 's#\[ "\$JBOSS_MODE" = "standalone" \]#\[ "\$JBOSS_MODE" = "sim_standalone" \]#' /tmp/sim-wildfly
exit
EOF
