3.4 bin

When the programs have been installed, the binary executables have been placed in $ADFBIN, typically $ADFHOME/bin, with names like 'adf.exe', 'band.exe', and so on. There will also be files 'adf', 'band'. The latter are scripts that execute the binaries.

You should use the script files, rather than the executables directly. The script files take care of several convenient features (like the BASIS key described in the ADF User's Guide), and they provide a correct environment for running in parallel. See also the sample run scripts and the Examples document.
