    Do you want to print the min value from column 3 only and the max value from column 4 only? Or if column 3 was: 1000, 120, 200 and column 4 was 100, 230, 10 would you want your results to be: sampleA 1000 10? Commented Aug 9, 2017 at 12:18
  • The max or min could be in column 3 or 4. Because this is DNA ORF information some reads are in reverse like the last line in the above example. Commented Aug 9, 2017 at 14:14
  • So in that case I believe both answers below wont work. NVM just noticed AFSHIN edited his answer. Commented Aug 9, 2017 at 14:30
  • awk's asort function will do the job Commented Aug 9, 2017 at 20:34
  • It appears that columns 1 and 2 have absolutely nothing to do with the output. Are the column 1 values identical in all rows? If not, I don't see how you can even define what the first field of output should be. Commented Aug 9, 2017 at 20:48
