filesplitter – split text files by line count

filesplitter is a command-line tool for dividing large text files into smaller files containing a specified number of lines. It is intended for situations where opening or processing a large text file as a single document is inconvenient.

The utility reads the source file sequentially and writes its contents into numbered output files. By default, each output contains 1,000 lines, apart from the final file, which contains any remaining lines.

Users can change the number of lines per output file and specify the character encoding used when reading the input. The program preserves the source filename extension and adds a numeric component to distinguish the resulting files.

filesplitter operates on text lines rather than arbitrary byte ranges. It is therefore suited to splitting large logs and other line-oriented text data, rather than dividing binary archives into fixed-size fragments.

This is free and open source software.

Key Features

• Divide large text files into smaller files.
• Use a default output size of 1,000 lines per file.
• Specify a different number of lines using -r or –row-count.
• Read the source filename using -f or –filename.
• Select the source text encoding using -e or –encoding.
• Use UTF-8 as the default input encoding.
• Process the source file line by line.
• Create sequentially numbered output files.
• Retain the original filename extension in generated files.
• Write remaining lines to the final output file.
• Display progress messages identifying output files as they are created.
• Report the total number of files generated.
