Ice Nine

Ice IX is a command-line toolset for managing file and directory permissions. It allows you to "freeze" permissions by saving them to a mapping file, and later "melt" them to restore the original settings. With options for recursive operations and directory inclusion, ice nine provides a simple way to revert permissions across your file system.

Modes of Operation

1. Freeze

This mod captures the current permissions of specified files and directories, storing them in a mapping file. Mod also adds permissions set in config file (ice-nine).

Flag	Long Form	Description
-a	--appendto	Adds files to the mapping file.
-b	--by	Appends the mapping file with listed paths.
-d	--directories	Includes directories for quarantine.
-r	--recursive	Appends directories and their files recursively.

Examples

• Freezes permissions for all files and directories (-d) in some/directory/with/files/ recursively (-r) and appends the data to mappingfile (-a).

iceix *freeze -rd some/directory/with/files/ --appendto mappingfile

• Freezes permissions for files listed (-b) in listfile.txt and appends (-a) the data to mappingfile.

iceix *freeze --by listfile.txt --appendto mappingfile

• Freezes permissions for all files in the current directory (*) and appends (-a) the data to mappingfile.

iceix *freeze * --appendto mappingfile

2. Melt

This mod restores the permissions of files and directories based on the data stored in the mapping file created by *freeze. These commands help you preserve file permissions and restore them later, ensuring consistency across different sessions, deployments, or system states.

Flag	Long Form	Description
-b	--by	Reverses permissions using the mapping file.
-a	--all	Runs the mod for all log files.
-r	--recursive	Reverses directories and their files recursively.

Examples

• Restores permissions for all (-a) files and directories listed (-b) in mappingfile.

iceix *melt --all --by mappingfile

• Restores permissions recursively (-r) for all files in some/directory/ based on mappingfile (-b).

iceix *melt --recursive some/directory/ --by mappingfile

• Restores permissions for some/file based on mappingfile (-b).

iceix *melt some/file --by mappingfile

3. Config

This mod displays base permissions for *freeze action.

iceix *config # FILE_QUARANTINE_MOD=000 DIRECTORY_QUARANTINE_MOD=700

Important Note

• It is crucial to add the configuration file ice-nine to ~/.config/ or modify the CONFIG_FILE constant in the i9-freeze.sh script to match the location of the configuration file.

Installation

Scripts can be used directly without special intervention (after setting config file (Important Notes section)) in file placement, but to improve usability and provide global access, it is recommended to follow these installation steps:

1. Move the main script iceix.sh to /usr/bin.
2. Remove the .sh extension.
3. Set the executable permissions.
4. Ensure that the SCRIPTS_DIR constant is updated to correctly locate the path to the program's mod files (i9-freeze.sh and i9-melt.sh).

After installation, Ice IX will be readily accessible from any terminal session, allowing for easy management of file and directory permissions.
