Snigdha OS Utilities Installation Instructions
|
||||
============================================
|
||||
|
||||
Thank you for installing Snigdha OS Utilities. Below are the steps and
|
||||
information regarding this package:
|
||||
|
||||
1. The following scripts are installed to /usr/local/bin:
|
||||
- snigdhaos-update.sh: A script for system update and maintenance.
|
||||
- snigdhaos-cleanup.sh: A script for cleaning up unused files and caches.
|
||||
- snigdhaos-backup.sh: A script for backing up important system files.
|
||||
- pacman: A script that intercepts the `pacman` command to use `snigdhaos-update.sh`.
|
||||
|
||||
2. Post-installation:
|
||||
- Ensure that the scripts in `/usr/local/bin` have the correct permissions.
|
||||
- If you want to use `snigdhaos-update.sh` as a replacement for `pacman -Syyu`, make sure that the `pacman` script is in place and executable.
|
||||
|
||||
3. Optional: You can create aliases or modify shell profiles to make usage more convenient.
|
||||
|
||||
Example usage:
|
||||
- Run `snigdhaos-update.sh` directly for system updates.
|
||||
- Use `snigdhaos-cleanup.sh` for system cleanup.
|
||||
- Use `snigdhaos-backup.sh` for backups.
