I test thess cmds on centos7 and works ok. Please provide your OS and version.
And on linux, your can use -l for linux mode, then you can combine cmds with &, like this.

# ./multissh -l -cmds "cd /home&&ls&&exit" -hosts "192.168.88.101" -u root -p password

When I add “-l” for linux mode，It worked！ Thanks！
