I earlier used to shebang with the path to bash : #!/usr/local/bin/bash Since my scripts sometimes needed to be ported to Linux and/or Cygwin, I often hacked the system with a symlink /bin/bash that pointed to the actual bash. Then I would use the symlink path - that worked under both FreeBSD and Linux. But a much better way now exists with env : #!/usr/bin/env bash The above shabang always works, no matter what the system, is fully portable, and is not too much typing either. Regards Manish Jain
