Invoking a command line with spaces from a variable in a Bash script [duplicate]

Answer 1

It is best not to use eval unnecessarily. Try not to put the command inside a variable. You can put the options as a variable though:

if [ ... ]
  string="Unix makefiles"
else
  string="MSYS Makefiles"
else
  string="...."
fi
cmake -G "$string" # Just call the command normally
