I need to make a script to extract the number that are not in a file.
Example:
I have file-A that has 100000 (70000-799999) numbers. And a file-B with number that already are in the system. Now I need to know/get the numbers that are not in system.
I was thinking something like this:
cat file-A | grep -v "file-b" >> file-C but it is not posible to grep -v from a text file. Maybe a loop file ?

filterdiff
FILTERDIFF(1)FILTERDIFF(1)NAME
filterdiff - extract or exclude diffs from a diff file
SYNOPSIS
filterdiff [-i PATTERN] [-p n] [--strip=n] [--addprefix=PREFIX]
[-x PATTERN] [--verbose] [-v] [-z] [-# RANGE | --hunks=RANGE]
[--lines=RANGE] [--annotate] [--format=FORMAT] [--as-numbered-lines=WHEN]
[file...]
filterdiff {--help | --version | --list | --grep ...}
DESCRIPTION
You can use filterdiff to obtain a patch that applies to files matching the shell wildcard PATTERN from a larger collection of patches. For
example, to see the patches in patch-2.4.3.gz that apply to all files called lp.c:
filterdiff -z -i '*/lp.c' patch-2.4.3.gz
If neither -i nor -x options are given, -i '*' is assumed. To remove lines from a file that are not part of a patch, you might do this:
filterdiff message > patch
Note that the interpretation of the shell wildcard pattern does not count slash characters or periods as special (in other words, no flags
are given to fnmatch). This is so that ``*/basename''-type patterns can be given without limiting the number of pathname components.
You can use both unified and context format diffs with this program.
OPTIONS -i PATTERN
Include only files matching PATTERN. All other lines in the input are suppressed.
-x PATTERN
Exclude files matching PATTERN. All other lines in the input are displayed.
-p n When matching, ignore the first n components of the pathname.
-# RANGE | --hunks=RANGE
Only include hunks within the specified RANGE. Hunks are numbered from 1, and the range is a comma-separated list of numbers or
``first-last'' spans; either the first or the last in the span may be omitted to indicate no limit in that direction.
--lines=RANGE
Only include hunks that contain lines from the original file that lie within the specified RANGE. Lines are numbered from 1, and the
range is a comma-separated list of numbers or ``first-last'' spans; either the first or the last in the span may be omitted to indi-
cate no limit in that direction.
--annotate
Annotate each hunk with the filename and hunk number.
--format=unified|context
Use specified output format.
--strip=n
Remove the first n components of pathnames in the output.
--addprefix=PREFIX
Prefix pathnames in the output by PREFIX.
--as-numbered-lines=before|after
Instead of a patch fragment, display the lines of the selected hunks with the line number of the file before (or after) the patch is
applied, followed by a TAB character and a colon, at the beginning of each line. Each hunk except the first will have a line con-
sisting of ``...'' before it.
-v, --verbose
Always show non-diff lines in the output. By default, non-diff lines are only shown when excluding a filename pattern.
-z Decompress files with extensions .gz and .bz2.
--help Display a short usage message.
--version
Display the version number of filterdiff.
--list Behave like lsdiff(1) instead.
--grep Behave like grepdiff(1) instead.
EXAMPLES
To see all patch hunks that affect the first five lines of a C file:
filterdiff -i '*.c' --lines=-5 < patch
To see the first hunk of each file patch, use:
filterdiff -#1 patchfile
To see patches modifying a ChangeLog file in a subdirectory, use:
filterdiff -p1 Changelog
To see the complete patches for each patch that modifies line 1 of the original file, use:
filterdiff --lines=1 patchfile | lsdiff |
xargs -rn1 filterdiff patchfile -i
To see all but the first hunk of a particular patch, you might use:
filterdiff -p1 -i file.c -#2- foo-patch
If you have a very specific list of hunks in a patch that you want to see, list them:
filterdiff -#1,2,5-8,10,12,27-
To see the lines of the files that would be patched as they will appear after the patch is applied, use:
filterdiff --as-numbered-lines=after patch.file
You can see the same context before the patch is applied with:
filterdiff --as-numbered-lines=before
patch.file
Filterdiff can also be used to convert between unified and context format diffs:
filterdiff -v --format=unified context.diff
