Starting ISA by /opt/IBM/ISA/ISA5/start_isa.sh script I obtained following error message:
./start_isa.sh: 40: ./start_isa.sh: function: not found
USAGE:
start_isa.sh [<tool_id>]
./start_isa.sh: 44: ./start_isa.sh: Syntax error: "}" unexpected
FIX is quite simple
The problem was that ./start_isa,sh use #!/bin/sh directive. Change the directive to #!/bin/bash on the first line of the ./start_isa,sh script.
