note vek <p>Well, <code>lsof</code> does work on multiple operating systems including Linux and Solaris. For <a href="http://www.die.net/doc/linux/man/man8/lsof.8.html">example</a>, <code>lsof</code> revision 4.74 lists information about files opened by processes for the following UNIX dialects: <code> AIX 5.[123] Apple Darwin 6.x and 7.x for Power Macintosh systems BSDI BSD/OS 4.3.1 for x86-based systems DEC OSF/1, Digital UNIX, Tru64 UNIX 4.0, and 5.1 FreeBSD 4.[2-9], 4.1[01], 5.[012] and 6.0 for x86-based systems FreeBSD 5.[012] and 6.0 for Alpha, AMD64 and Sparc64 based systems HP-UX 11.00 and 11.11 Linux 2.1.72 and above for x86-based systems NetBSD 1.[456] and 2.x for Alpha, x86, and SPARC-based systems NEXTSTEP 3.[13] for NEXTSTEP architectures OpenBSD 2.[89] and 3.[0123456] for x86-based systems OPENSTEP 4.x Caldera OpenUNIX 8 SCO OpenServer Release 5.0.6 for x86-based systems SCO|Caldera UnixWare 7.1.4 for x86-based systems Solaris 2.6, 8, 9 and 10 </code></p> <p>The path to where <code>lsof</code> is installed my vary slightly but you can modify your code to pick the right one depending on which OS you are on at the time. So [McDarren]'s example should give you what you need.</p> <!-- Node text goes above.
