Add a new utility script for splitting files into 1GB chunks:
,split-1G - File splitting wrapper
- Splits one or more files into 1GB chunks with numeric suffixes
- Uses split(1) with --bytes=1G for consistent chunk sizes
- Generates 5-digit numeric suffixes (.00000, .00001, etc) for up to 99,999 parts
- Outputs verbose progress information during splitting
- Fails fast with set -e to catch errors during multi-file operations
- Added to tb-scripts package with coreutils as runtime dependency
This is useful for preparing large files for upload to services with file
size limits, or for splitting backups/archives into manageable pieces.
Example usage:
,split-1G large-backup.tar.gz
# Creates: large-backup.tar.gz.00000, large-backup.tar.gz.00001, ...
