NAME

       parrot_package_run - repeat a program within the package with the help of parrot_run

SYNOPSIS

       parrot_package_run --package-path your-package-path [command]

DESCRIPTION

       If  parrot_run  is  used  to repeat one experiment, one mountlist must be created so that the file access
       request of your program can be redirected into the package. parrot_package_run  is  used  to  create  the
       mountlist  and  repeat  your  program within the package with the help of parrot_run and mountlist. If no
       command is given, a /bin/sh shell will be returned.

OPTIONS

        -p, --package-path
              The path of the package.

        -e, --env-list
              The path of the environment file, each line is in the format of <key>=<value>. (Default:  package-
              path/env_list)

        -h, --help
              Show this help message.

EXIT STATUS

       On success, returns zero. On failure, returns non-zero.

EXAMPLES

       To repeat one program within one package /tmp/package in a bash shell:

               % parrot_package_run --package-path /tmp/package /bin/bash

       After  the execution of this command, one shell will be returned, where you can repeat your original pro‐
       gram. After everything is done, exit parrot_package_run:

               % exit

       You can also directly set your command as the arguments of parrot_package_run. In this case, parrot_pack‐
       age_run will exit automatically after the command is finished, and you do not need to use exit  to  exit.
       However, your command must belong to the original command set executed inside parrot_run and preserved by
       parrot_package_create.

               % parrot_package_run --package-path /tmp/package ls -al

       Here  is  a short instruction about how to make use of parrot_run, parrot_package_create and parrot_pack‐
       age_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/bash

       After  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  en‐
       vironment variables will be generated.  After everything is done, exit parrot_run:

               % exit

       Step 2: Using parrot_package_create to generate a package.

               % parrot_package_create --name-list namelist --env-path envlist --package-path /tmp/package

       At 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 /bin/bash

       After  the execution of this command, one shell will be returned, where you can repeat your original pro‐
       gram. After everything is done, exit parrot_package_run:

               % exit
