Just in case ... if writing new scripts, it's advisable to use 'j',
which various tar programs are settling on, migrating away from 'y'.
Hrm, OpenBSD tar(1) uses -I with a parameter for something else:
-----------------------------< cut here >-------------------------------
-I file This is a positional argument which reads the names of
files to archive or extract from the given file,
one per line.
-----------------------------< cut here >-------------------------------
Unfortunately, some quick googling hasn't turned up any evidence to back
up my assertion re '-j'. :^( Ah, hold on, FreeBSD 4 box, tar(1) manual
page, states:
-----------------------------< cut here >-------------------------------
COMPATIBILITY
The -y is a FreeBSD localism. The GNU tar maintainer has now choosen -j
as the offical bzip2(1) compression option in GNU tar 1.13.18 and later.
The -I option is for compatibility with Solaris's tar.
