xdelta

KDE.org asked how to use xdelta3. Like gzip with the additional -s SOURCE. Like gzip, -d means to decompress, and the default is to compress. For output, -c and -f flags behave likewise. Unlike gzip, xdelta3 defaults to stdout (instead of having an automatic extension). Without -s SOURCE, xdelta3 behaves like gzip for stdin/stdout purposes. See also.

Compress examples:

xdelta3 -s SOURCE TARGET > OUT
xdelta3 -s SOURCE TARGET OUT
xdelta3 -s SOURCE < TARGET > OUT

Decompress examples:

xdelta3 -d -s SOURCE OUT > TARGET
xdelta3 -d -s SOURCE OUT TARGET
xdelta3 -d -s SOURCE < OUT > TARGET
