Attached is a program to compile, cache and execute D source code files or 'pseudo shell scripts' (using the she-bang syntax with dmd v0.146 or above) on Linux systems.

It will cache the executable in the /tmp directory by default and will re-compile the executable if any of the source file, the compiler or rdmd itself is newer than the cached executable. It can optionally use gdmd if specified, but uses dmd by default.

# rdmd --help
        rdmd [D compiler arguments] [rdmd arguments] progfile.d [program

rdmd arguments:
        --help                  This message
        --force                 Force re-compilation of source code [default
= do not force]
        --compiler=(dmd|gdmd)   Specify compiler [default = dmd]
        --tmpdir=tmp_dir_path   Specify directory to store cached program
and other temporaries [default = /tmp]

        dmd or gdmd must be in the current user context $PATH
        rdmd does not support execution of D source code via stdin
        rdmd will only compile and execute files with a '.d' file extension
