[Solaris]
1. 查看内核是32位还是64位:
# isainfo -kv
2. 查看程序执行时所有的系统调用:
# truss
3. 查看特定网络接口与特定主机间的流量:
# snoop -d host
4. 关闭beep:
# /usr/openwin/bin/xset b off
5. 查看文件来自哪个包:
# pkgchk -lp {file}
6.查看CPU的个数和频率:
# psrinfo -v

[OpenSolaris]
1. 恢复系统到初始安装时的快照:
$ pfexec mkdir /altroot
$ pfexec zpool import -R /altroot -f rpool
$ pfexec zfs rollback -R rpool/ROOT/opensolaris@install
$ pfexec reboot
2. 用live cd启动mount以前的opensolaris:
$pfexec su -
#zpool import -f rpool
#beadm mount opensolaris /a
3. OpenSolaris增加swap空间(32bit) [64bit无需将每个swap文件分割为2G]:
#
# Set the default swap rpool to 2G
#
swap -d /dev/zvol/dsk/rpool/swap
zfs set volsize=2G rpool/swap
#
# Create three more 2G rpool swap files
#
zfs create -V 2G rpool/swap1
zfs create -V 2G rpool/swap2
zfs create -V 2G rpool/swap3
vi /etc/vfstab (look like this)
/dev/zvol/dsk/rpool/swap - - swap - no -
/dev/zvol/dsk/rpool/swap1 - - swap - no -
/dev/zvol/dsk/rpool/swap2 - - swap - no -
/dev/zvol/dsk/rpool/swap3 - - swap - no -
/sbin/swapadd
