% parrot_package_create --name-list namelist --env-list envlist --package-path /tmp/packageAfter executing this command, one package with the path of /tmp/package will be generated.
Here is a short instruction about how to make use of parrot_run, parrot_package_create and parrot_package_run to generate one package for your experiment and repeat your experiment within your package.
Step 1: Run your program under parrot_run and using --name-list and --env-list parameters to record the filename list and environment variables.
% parrot_run --name-list namelist --env-list envlist /bin/bashAfter the execution of this command, you can run your program inside parrot_run. At the end of step 1, one file named namelist containing all the accessed file names and one file named envlist containing environment variables will be generated. After everything is done, exit parrot_run:
Step 2: Using parrot_package_create to generate a package.
% parrot_package_create --name-list namelist --env-path envlist --package-path /tmp/packageAt the end of step 2, one package with the path of /tmp/package will be generated.
Step 3: Repeat your program within your package.
% parrot_package_run --package-path /tmp/package --shell-type bash ...After the execution of this command, one shell will be returned, where you can repeat your original program (Please replace --shell-type parameter with the shell type you actually used). After everything is done, exit parrot_package_run:
% exitYou can also add the dependencies recorded in a new namelist file, namelist1, into an existing package:
% parrot_package_create --name-list namelist1 --env-list envlist1 --new-env envlist1 --add /tmp/packageAfter executing this command, all the new dependencies mentioned in namelist1 will be added into /tmp/package, the new envlist, envlist1, will also be added into /tmp/package with the name specified by the --new-env option.
