I was facing the same issue while configuring SWSE, it was failing at the step UpdateMimeTypes
Siebel version 22.214.171.124
Web Server - OHS 11g
OS - Oracle Linux 4 update 5
Below step helped resolve my issue, hopefully it will help here

You need to open scripts under sweapp/install_script/install and check whether it is written "head -1" command syntax or "head -n 1"
Please check on this. If it mentioned as "head -1" , replace all scripts to use "head -n 1"
