Top Forums Shell Programming and Scripting Remove or rename based on contents of file Post 302943592 by Don Cragun on Sunday 10th of May 2015 09:23:49 PM

I'm lost.

The first line in file1.txt has DTE3504500000004 in field 5. From your description (with the 1st field on that line being No Match), the last four lines of file2.txt should have been removed; not the 3rd and 4th lines.

The second line in file1.txt has DTE3504500000005 in field 5. Since that string does not appear in file2.txt, why should anything in file2.txt be changed because of that line?
