Usage: pkgdiff [OPTION] FILE1 FILE2
|
|
Show which files are new and which are removed between two tar archives.
|
|
The tar archives may be uncompressed, or compressed with gzip, bzip2,
|
|
xz, or lzip. Also works with .rpm and .deb.
|
|
|
|
--help display this help and exit
|
|
-c use ANSI color with default tree mode
|
|
-a show simple text (ASCII) diff of package file lists
|
|
|
|
By default, the trees are drawn with in crude ASCII with no color. For
|
|
the full-color effect, try something like this:
|
|
|
|
pkgdiff -c package1 package2 | less -r
|
|
|
|

|

# --help doesn't return
