Bone Study Notes

When we enter a new Linux server environment, we should quickly learn the basic hardware and software information of the server. The following is an example:

# Clear

# Dmidecode | grep Product (Server Model)
Product Name: Lenovo WQ R510 G6
Product Name: DPX1066RK
# Cat/proc/cpuinfo | grep name | cut-f2-d: (which indicates there are 8 CPUs ?)
Intel (R) Xeon (R) CPU E5410 @ 2.33 GHz
Intel (R) Xeon (R) CPU E5410 @ 2.33 GHz
Intel (R) Xeon (R) CPU E5410 @ 2.33 GHz
Intel (R) Xeon (R) CPU E5410 @ 2.33 GHz

Intel (R) Xeon (R) CPU E5410 @ 2.33 GHz
Intel (R) Xeon (R) CPU E5410 @ 2.33 GHz
Intel (R) Xeon (R) CPU E5410 @ 2.33 GHz
# Cat/proc/cpuinfo | grep physical (Originally 4-core, indicating only 2 CPUs)

If you are using the SecureCRT software to log on to the server, the above commands do not need to be typed one by one. As shown below, you can write a vbs script, then Run the vbs Script in secureCRT-Script-Run. is it very important ?!
Linux_info (root). vbs

ASP/Visual Basic Code
# $ Language = "VBScript"
# $ Interface = "1.0"
