# rpm -qa | grep perl perl-HTML-Parser-3.55-1.fc6 perl-Net-Telnet-3.03-5 perl-LDAP-0.33-4.el5_8 perl-XML-LibXML-1.58-6
其它经常使用命令整理例如以下:
df –F ufs –o i
isalist –v
对于“/proc”中文件可使用文件查看命令浏览其内容,文件里包括系统特定信息:
主机CPU信息:Cpuinfo
主机DMA通道信息:Dma
文件系统信息:Filesystems
主机中断信息:Interrupts
主机I/Oport号信息:Ioprots
主机内存信息:Meninfo
Linux内存版本号信息:Version
备注: proc – process information pseudo-filesystem 进程信息伪装文件系统
