Geçenlerde tesadüfen SysInfo isimli script set'ine rastladım.  Bu script set'i FreeBSD sisteminize ait en ince bilgileri raporlamak üzere Daniel Gerzo isimli bir üniversite öğrencisi tarafından bitirme tezi olarak yazılmış.

Oldukça kullanışlı olan bu script setini şu adresten indirebiliyorsunuz:  http://people.freebsd.org/~danger/sysinfo/. En son sürüm 1.0.2 olarak görünüyor. Script'in çıktısı epey detaylı, ben VMWare guest olarak kurulu olan bir FreeBSD 7.2'de çalıştırdım.

Çıktısı şu şekilde:

# sh sysinfo -a
