       So what is patchview? It is a wrapper of filterdiff for use with numbered files.

           patchview

       (without args) is equivalent to: lsdiff --number


           patchview -F2-
       (or with any other args) is equivalent to: filterdiff -F2- (or whatever arguments are supplied)

       There are two scripts for working with git (gitdiff and gitdiffview) and two for svn (svndiff and
       svndiffview).

           svndiff

           gitdiff

       (without args) will give the list of files modified

           svndiff -F1

           gitdiff -F1

       will show the patch of file #1

           svndiffview

           gitdiffview

       pipe all patches through filterdiff to vim - -R (in read-only mode, easy to quit), showing complete patch
       with color.

           svndiffview -F2

           gitdiffview -F2

       (or any other args) will pipe patch of file #2 to vim - -R

       We can make the following one-line script with the name difftotrunk.sh, to view the differences of two
       directories or svn repos (trunk and .)

           diff ../trunk . -ru -x .svn | patchview "$@"

           ./difftotrunk.sh , will show all different files and his number.

           ./difftotrunk.sh -F3,4 , will show the differences of files #3 and #4 only.

           ./difftotrunk.sh -F3 -#1 , will show only hunk #1 of file #3.

           ./difftotrunk.sh -F3 -#x1 , will show the differences of files #3 without hunk #1 (x means that exclude).

       patchview - Without options, show numbered files modified by the patch. With options, behave as
       filterdiff.

-n, --line-number
           Display the line number that each patch begins at. If verbose output is requested (using -nv), each
           hunk of each patch is listed as well.

           For each file that is modified, a line is generated containing the line number of the beginning of
           the patch, followed by a Tab character, followed by the name of the file that is modified. If -v is
           given once, following each of these lines will be one line for each hunk, consisting of a Tab
           character, the line number that the hunk begins at, another Tab character, the string “Hunk #”, and
           the hunk number (starting at 1).

           If the -v is given twice in conjunction with -n (i.e.  -nvv), the format is slightly different:
           hunk-level descriptive text is shown after each hunk number, and the --number-files option is
           enabled.

       -N, --number-files
           File numbers are listed, beginning at 1, before each filename.

       -#RANGE, --hunks=RANGE
           Only list hunks within the specified RANGE. Hunks are numbered from 1, and the range is a
           comma-separated list of numbers or “first-last” spans, optionally preceded by a modifier 'x' which
           inverts the entire range; either the first or the last in the span may be omitted to indicate no
           limit in that direction.

       --lines=RANGE
           Only list 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,
           optionally preceded by a modifier 'x' which inverts the entire range; either the first or the last in
           the span may be omitted to indicate no limit in that direction.

       -F=RANGE, --files=RANGE
           Only list files indicated by the specified RANGE. Files are numbered from 1 in the order they appear
           in the patch input, and the range is a comma-separated list of numbers or “first-last” spans,
           optionally preceded by a modifier 'x' which inverts the entire range; either the first or the last in
           the span may be omitted to indicate no limit in that direction.

       -pn, --strip-match=n
           When matching, ignore the first n components of the pathname.

       --strip=n
           Remove the first n components of the pathname before displaying it.

       --addprefix=PREFIX
           Prefix the pathname with PREFIX before displaying it.

       -s, --status
           Show file additions, modifications and removals. A file addition is indicated by a “+”, a removal by
           a “-”, and a modification by a “!”.

       -E, --empty-files-as-removed
           Treat empty files as absent for the purpose of displaying file additions, modifications and removals.

       -iPATTERN, --include=PATTERN
           Include only files matching PATTERN.

       -xPATTERN, --exclude=PATTERN
           Exclude files matching PATTERN.

       -z, --decompress
           Decompress files with extensions .gz and .bz2.

       -H, --with-filename
           Print the name of the patch file containing each patch.

       -h, --no-filename
           Suppress the name of the patch file containing each patch.

       -v, --verbose
           Verbose output.

       --help
           Display a short usage message.

       --version
           Display the version number of patchview.

       --filter
           Behave like filterdiff(1) instead.

       --grep
           Behave like grepdiff(1) instead.
