all all all have been dealing with Linux recently. Since I have a weak foundation in this area, I had to buy this book by Brother Niao and read it. It feels pretty good. I think the troublesome thing about Linux compared to Windows is that many things need to be controlled by commands. Of course, this is also the reason why many people like Linux. It is relatively short but powerful. In order to make it easier for everyone to find Linux-related commands, I will list the commands I know for your reference only:
System information
arch Display the processor architecture of the machine (1)
uname -m displays the machine's processor architecture (2)
uname -r displays the kernel version being used
dmidecode -q displays hardware system components - (SMBIOS / DMI)
hdparm -i /dev/hda list Architectural characteristics of a disk
hdparm -tT /dev/sda performs test read operations on the disk
cat /proc/cpuinfo displays CPU info information
cat /proc/interrupts displays interrupts
cat /proc/meminfo Verify memory usage
cat /proc/swaps Display which swaps are used
cat /proc/version Display the kernel version
cat /proc/net/dev Display network adapter and statistics
cat /proc/mounts Display the loaded file system
lspci -tv List PCI devices
lsusb -tv Display USB devices
date Display the system date
cal 2007 Display the calendar for 2007
date 041217002007.00 Set date and time - month, day, hour, minute, year, second
clock -w Save time modification to BIOS
Shutdown (system shutdown, restart and logout)
shutdown -h now Shut down the system (1)
init 0 Shut down the system (2)
telinit 0 Shut down the system (3)
shutdown -h hours:minutes & Shut down the system according to the scheduled time
shutdown -c Cancel the system shutdown according to the scheduled time
shutdown -r now Restart (1)
reboot Restart (2)
logout Logout
##Check whether the ssh service is installed: rpm -qa | grep ssh
Install ssh service: yum (-y) install ssh (redhat system such as: redhat , centos) or sudo apt -get install ssh (debian system such as: ubunt)
View the process the program is running: ps -ef | grep weblogic
Kill Process: kill -9 process number
Start ssh (generally called sshd) process: service sshd start or Use /etc/init.d/sshd start
Check the output file: tail -f nohup.out Background startup: nohup ./startWeblogic.sh |

scp fromfilePath tofilePath(userName@IP:/filePath) forExample: scp isportal_uum_sj.tar.gz.0928 root@172.16.66.18:/opt /apache-tomcat-6.0.37/webapps |
ntpdate cn.pool.ntp.org sysctl -w net.ipv4.tcp_tw_recycle=1
yum -y install gcc make gcc-c++ openssl-devel
