Build status:

An implementation of the UNIX tail command in .Net.

If you just want to try it out I recommend installing tailDotNet using Chocolatey: https://chocolatey.org/packages/taildotnet. Simply open a command prompt with administrative privileges and type choco install taildotnet

Start tailing a file by typing tail -f someFileName.log in a command prompt.

Only interested of changes that contains "error"? Use the includefilter parameter:

tail -f someFileName.log --includefilter error or the shorthand form tail -f someFileName.log -i error

You can also exclude stuff from the tail output by using the excludefilter. Like so:

tail -f someFileName.log --excludefilter aCommonErrorMessageThatOccursAllTheTimeButYouDontBotherToFix
