Top Forums UNIX for Beginners Questions & Answers Splitting a file based on negative and positive numbers Post 303034642 by RudiC on Wednesday 1st of May 2019 02:57:19 PM

Some input and desired output samples might help.
I don't see the split nor the csplit tool to distribute lines to different target files based on a single field's contents. Try instead
Code:
awk -F"|" '{print > ($6<0?"NEG.TXT":"POS.TXT")}' file

If you don't want the sixth field to be the selector but the non-predetermined field labeled "F", use nezabudka's proposal to determine the relevant field number. Make sure there's only one field labeled "F"!
