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?

mv(1)							      General Commands Manual							     mv(1)

Name
       mv - move or rename files

Syntax
       mv [-i] [-f] [-] file1 file2

       mv [-i] [-f] [-] file... directory

Description
       The command moves (changes the name of) file1 to file2.

       If  file2  already  exists,  it is removed before file1 is moved.  If file2 has a mode which forbids writing, prints the mode and reads the
       standard input to obtain a line.  If the line begins with y, the move takes place.  If it does not, exits.  For further information, see

       In the second form, one or more files (plain files or directories) are moved to the directory with their original file-names.

       The command refuses to move a file onto itself.

Options
       -		   Interprets all following arguments as file names to allow file names starting with a minus.

       -f		   Force. This option overrides any mode restrictions or the -i switch.

       -i		   Interactive mode.  If a move is to supersede an existing file, the system prompts youw with the name of the	file  fol-
			   lowed  by  a question mark.	If you type a string that begins with y, the move occurs.  If you type any other response,
			   the move does not occur.

Restrictions
       If file1 and file2 lie on different file systems, must copy the file and delete the original.  In this case the owner name becomes that	of
       the copying process and any linking relationship with other files is lost.
