* Wrote basename
* Wrote basename.
* tar wouldn't create directory entries that don't end in '/',
now it does (fix thanks to Avery Pennarun <apenwarr@worldvisions.ca>)
now it does (thanks to Avery Pennarun <apenwarr@worldvisions.ca>)
* Several fixes from Pavel Roskin <pavel_roskin@geocities.com>:
- When `tail' fails to open a file it now exits.
- When `syslogd' is given the `-n' option it should still use
fork() for running klogd.
* nslookup types are now changed to u_int32_t (instead of uint32_t)
changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
* Fixed "du" so it gives the same answers as GNU "du" (busybox du used to
count hard-linked files more then once). Many thanks to
