See the bottom section for a Windows version of this function. call random function to generate from 1-300 (uniq - without repetition) and use 'head -num tail -1' to get that line and redirect to new file.

Python-based function, adapted from scai's answer:.POSIX-compliant function based on awk, sort, and cut, adapted from the OP's own answer:.This is important when piping the function output to a pipe that is closed early, such as when piping to head. The functions take extra steps to handle SIGPIPE in the usual way (quiet termination with exit code 141), as opposed to breaking noisily.The functions take not only stdin input, but alternatively also filename arguments.The existing answers are packaged into flexible shell functions: Free online tools are available on Home to improve text in a few clicks.This answer complements the many great existing answers in the following ways: Get rid of a large amount of routine work thanks to the quick formatting of texts of any type and size. Text Converter does not require payment or registration. Use the tool for your work tasks an unlimited number of times.

Additionally, functions are available for removing duplicate parts of text, grouping paragraphs and clearing lines from spaces. The syntax: traintestsplit (x,y,testsize,trainsize,randomstate,shuffle,stratify) Mostly, parameters x,y,testsize. You can quickly swap paragraphs between each other.
