parrot_package_run(1)

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 =. (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 program. 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_package_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_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/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 environment 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
