It doesn’t.
This works:
94 ssh root@$hostbase "
95 PS4='(${hostbase%%.*})++++ '
96 set -ex
97 psql -U veraweb -h 127.0.0.1 veraweb
98 rm -rf /var/lib/tomcat$tomcat/webapps/veraweb
99 rm -rf /var/lib/tomcat$tomcat/webapps/vwor
100 " <core/src/main/files/upgrade.sql
Here, $hostbase and $tomcat are expanded locally. Full code:
https://evolvis.org/plugins/scmgit/cgi-bin/gitweb.cgi?p=veraweb/veraweb.git;a=blob;f=upload.sh;h=b8b0cf92ad36dbc929afd86effe44d9bec888344;hb=HEAD
If you wish for no local expansion, quote locally, such as:
ssh -l luser remotehost '
command1
command2
…
'
Quote any ‘'’ inside as “'\''”, that’s it. (Easily done, for
example in AT&T ksh93/GNU bash/mksh: ${cmd//\'/\'\\\'\'})
