You can use both unified and context format diffs with this program.
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.
-# RANGE, --hunks=RANGE
-p n, --strip-match=n
-i PATTERN, --include=PATTERN
-x PATTERN, --exclude=PATTERN
To sort the order of touched files in a patch, you can use:
lsdiff patch | sort -u | \ xargs -rn1 filterdiff patch -i
To show only added files in a patch:
lsdiff -s patch | grep '^+' | \ cut -c2- | xargs -rn1 filterdiff patch -i
To show the headers of all file hunks:
lsdiff -n patch | (while read n file do sed -ne "$n,$(($n+1))p" patch done)
