Slicy

A console utility that splits stdin into separate files. The names of the output files are generated from the current time according to the specified pattern. It is guaranteed that the files will be split at the end of the line ('\n' - 0x0A).

You can also set limits on the desired size of the output files; limits can be on both the minimum and maximum sizes.

If the generated path contains non-existent directories, then such directories will be created automatically.

Usage

slicy [-c COMPRESS_PROGRAM] [{-s|-S} SIZE] PATTERN
	[-c COMPRESS_PROGRAM]: compress output stream with specified command.
		Examples: gzip, 'gzip -9', zstd
	[-s SIZE]: do not create a new file until the current size exceeds

	SIZE: size specification. Examples:
