I would like to delete all the lines not only one line?,

FYI, the file2 has 2 time the same value repetead.. for that I would like to delete both lines
All the solution's provided works perfect.

but i prefer rwuerth's solution. grep -vf

Code:
$ cat file2
A          2915.0  7325.01212 75   2   5248969 78 46

$ cat file1

merge

merge(1)						      General Commands Manual							  merge(1)

NAME

       merge - three-way file merge

SYNOPSIS

       file1 file2 file3

DESCRIPTION

       combines  two  files  that are revisions of a single original file.  The original file is file2, and the revised files are file1 and file3.
       identifies all changes that lead from file2 to file3 and from file2 to file1, then deposits the merged text into file1.	If the	option	is
       used, the result goes to standard output instead of file1.

       An  overlap  occurs  if both file1 and file3 have changes in the same place.  prints how many overlaps occurred, and includes both alterna-
       tives in the result.  The alternatives are delimited as follows:

	      lines in file1
	      lines in file3

       If there are overlaps, edit the result in file1 and delete one of the alternatives.

       This command is particularly useful for revision control, especially if file1 and file3 are the ends of two branches that have file2  as  a
       common ancestor.

EXAMPLES

       A typical use for is as follows:

	      1.   To  merge  an  RCS branch into the trunk, first check out the three different versions from RCS (see co(1)) and rename them for
		   their revision numbers: 5.2, 5.11, and 5.2.3.3.  File 5.2.3.3 is the end of an RCS branch that split off the trunk at file 5.2.

	      2.   For this example, assume file 5.11 is the latest version on the trunk, and is also a revision  of  the  "original"  file,  5.2.
		   Merge the branch into the trunk with the command:

	      3.   File  5.11  now  contains  all  changes  made on the branch and the trunk, and has markings in the file to show all overlapping
		   changes.

	      4.   Edit file 5.11 to correct the overlaps, then use the command to check the file back in (see ci(1)).
