Sebenarnya udah agak lama aku nyari perintah di linux untuk mengetahui jenis ditro yang digunakan, karena beda dengan freebsd yg kalau di uname -a langsung deh kliatan freebsd versi brapa stable atau release dll. coba nih bandingkan

uname -a pada FreeBSD :

FreeBSD 6.2-RELEASE-p1 #0: Tue Feb 27 17:40:07 WIT 2007 root@gateway.net:/usr/src/sys/i386/compile/ROUTER i386


uname -a pada pada unknown linux box :

Linux cobanet 2.6.21.5-smp #2 SMP Tue Jun 19 14:58:11 CDT 2007 i686 Intel(R) Pentium(R) D CPU 2.66GHz GenuineIntel GNU/Linux

Nah kan.. bagi saya yang kurang familier dengan linux apalagi versi kernel2nya.. susah juga.

Setelah tanya sini situ, ternyata bisa dicoba dengan cara
# more /etc/issue

Tapi pada linux box yg saya test keluarnya gini :

root@cobanet:~# more /etc/issue
Welcome to \s \r (\l)

Saya masih penasaran, akhirnya googling dannnnn alhamdulillah ketemu scriptnya, ini nih scriptnya :

#!/bin/ksh

system=`uname -s| tr 'A-Z' 'a-z'`

cputype=`uname -m`
