Running a speed test would be interesting of course, but I point to an advantage for most of us: with 32 bit uids the /var/log/lastlog file can become enormous. Fortunately (for systems that support sparse files), it is sparse. The example below also demonstrates that cp preserves sparseness by default. /var/log: cp lastlog lastlog2 /var/log: cat lastlog > lastlog3 /var/log: ls -l lastlog* -rw-rw-rw- 1 p-humble sw 3055044 Mar 13 11:23 lastlog -rw-rw-rw- 1 p-humble sw 3055044 Mar 13 12:06 lastlog2 -rw-rw-rw- 1 p-humble sw 3055044 Mar 13 12:07 lastlog3 /var/log: du lastlog* 64 lastlog 64 lastlog2 2880 lastlog3 Pierre -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
