linecounter

An easy to use and fast tool that counts the number of lines from files.

Think of it as wc -l and grep -c merged in a single tool with compressed file support. It also doesn't count lines on unsupported files format (because yes, wc -l gives you the number of text lines in a video), and nicely formats the output.

For now, it's already faster than things like zcat myfile.gz | wc -l or zgrep -c '>' myHugeFastaFile.gz. However, it's way slower than a simple wc -l or grep -c. Help's needed to figure out why!

Supported compression format:

• gzip
• bzip2

Installation
