shell script not executing

Question

I am trying to run a shell script on unix, but I am getting an error specifying it can't be executed.

Command

Unix> Abc.ksh
ksh: Abc.ksh: cannot execute

Also tried

pcasvs17 >  ./Abc.ksh
ksh: ./Abc.ksh: cannot execute

The script starts with

 #!/bin/ksh

Any help is appreciated.

Answer 1

chmod +x Abc.ksh and try again with ./Abc.ksh
