[ale] mv files with tar??

[Charles Shapiro]

I've always thought that having extra cats cross your path was bad luck.
As written here, the extract-side tar will try to extract from the file
"1"; you probly meant "tar -x -b 1 -f -" there. I like seeing the files
scroll by, so I also add a "-v" to the extract side. The "&&" is a nice
touch; it means that the 2nd tar(1) will execute iff the 'cd' works
(e.g. the directory argument exists).

IIRC there are some special crunchy parts in HP-[S]UX to this command
string. Possibly an extra argument or two to the extract-side tar(1) to
make sure you get the source ownership instead of yourself ? In Linux's
tar it's "--same-owner". It might be worth a visit to the man page to
double check this. I remember that eventually I stuck it in a shell
alias to keep from having to memorize the HP quirks.
