Top Forums UNIX for Beginners Questions & Answers How to copy only some lines from very big file? Post 302965782 by RudiC on Wednesday 3rd of February 2016 04:15:48 AM
Old 02-03-2016
As no samples are available, I have to guess there is something special with the input file. Did you test the suggestions with a simplified (abbreviated) dummy input file, possibly created copying a section of the original? Please post a (small but representative) hexdump of the input. Should look like
Code:
od -tx1c file
0000000  23  65  6d  70  6e  6f  0a  65  6e  61  6d  65  0a  6a  6f  62
          #   e   m   p   n   o  \n   e   n   a   m   e  \n   j   o   b
