Cat out at given offset with given count/length in different formats
I have huge json and other text files and i have to look sometimes is
something wrong with this files. For example json reader raised exceptions
and so on. And then i have to look why. And for this case i wrote this
small tool.
I know i can you existing great tools like sed and awk and so on. But
sometimes this great command line tools are a little oversized for me and
and i like to code in C++. So why not a tiny tool like this to solve this
task.
