Siebel 16 and Oracle cache Server issue

Siebel 16 has scripts to list/start/stop cache server under /siebel/16/ses/gtwysrvr/bin folder but when I am trying to use list_cs it is returning garbage characters.

pipe@lnxapp31:/siebel/16/ses/gtwysrvr->. ./siebenv.sh

pipe@lnxapp31:/siebel/16/ses/gtwysrvr->cd bin

pipe@lnxapp31:/siebel/16/ses/gtwysrvr/bin->./list_cs -r /siebel/16/ses

pipe@lnxapp31:/siebel/16/ses/gtwysrvr/bin->­æ¥æ®ã´ â½åä±æ´çæbel/16/ses
