Question Comparison and editing of files using awk.(And also a possible bug in awk for loop?)
I have two files which I would like to compare and then manipulate in a way.

File1:

Code:
pictures.txt 1.1 1.3
dance.txt 1.2 1.4
treehouse.txt 1.3 1.5


File2:
Code:
pictures.txt 1.5 ref2313 1.4 ref2345 1.3 ref5432 1.2 ref4244
dance.txt 1.6 ref2342 1.5 ref2352 1.4 ref0695 1.3 ref5738 1.2 ref4948 1.1
treehouse.txt 1.6 ref8573 1.5 ref3284 1.4 ref5838 1.3 ref4738 1.2 ref4573 1.1

What I want is the file and the version number to be printed into a file between the two version numbers in shown in file1. So the output should be:


Code:
pictures.txt 1.3 ref5432 1.2 ref4244 1.1
dance.txt 1.4 ref0695 1.3 ref5738 1.2 ref4948
treehouse.txt 1.5 ref3284 1.4 ref5838 1.3 ref4738


Also, rdcwayx identified a possible bug in the awk for loop which no one seems to have picked up on:

Code:
$ awk 'BEGIN {for (i=1.5;i>=1.2;i-=0.1) print i}'
1.5
1.4
1.3

$ awk 'BEGIN {for (i=15;i>=12;i-=1) print i}'
15
14
13
12

In the first example there should be 4 outputs, however only 3, whilst in the 2nd one we get all 4.

ECACCESS-FILE-MOVE(1p)					User Contributed Perl Documentation				    ECACCESS-FILE-MOVE(1p)

NAME

       ecaccess-file-move - Move or Rename ECaccess Files

SYNOPSIS

       ecaccess-file-move -version|-help|-manual

       ecaccess-file-move [-debug] source-ecaccess-file target-ecaccess-file

DESCRIPTION

       Allow moving an ECaccess File. When the move occurs within the same ECaccess File System then it is a rename. When the move occurs across
       two different ECaccess File Systems then first a copy is done and then a delete of the original file is done (e.g. similar to ecaccess-
       file-copy ... -erase).

       The source-ecaccess-file and target-ecaccess-file are in the form [domain:][/user-id/]path. Please read the "Shell commands -> File
       Management" section of the "ecaccess" guide for more information on the ECaccess File System.

ARGUMENTS

       source-ecaccess-file
	       The source ECaccess File name.

       target-ecaccess-file
	       The target ECaccess File name.

OPTIONS

       -version
	       Display version number and exits.

       -help   Print a brief help message and exits.

       -manual Prints the manual page and exits.

       -debug  Display the SOAP messages exchanged.

EXAMPLES

       ecaccess-file-move ec:test1.txt ec:test2.txt

       Rename the test1.txt file in the ECFS directory of the authenticated user in test2.txt.

       ecaccess-file-move ec:test1.txt home:test2.txt

       Copy the test1.txt file from the ECFS directory of the authenticated user to the test2.txt file in the $HOME directory of the authenticated
       user, then delete the test1.txt file from ECFS.
