Bash Script to View System Information on Linux Every Time You Log into Shell
|
||||
======
|
||||
|
||||
There are several commands in Linux to obtain system information such as processor information, manufacturer name, and serial number, etc,.
|
||||
|
||||
You may need to run several commands to collect this information.
|
||||
|
||||
Also, it is very difficult to remember all the commands and their options.
|
||||
|
||||
Instead you can write a **[shell script][1]** to customize the output based on your needs.
|
||||
|
||||
In the past we have written many **[bash scripts][2]** for a variety of purposes.
|
||||
|
||||
Today, we came up with a new shell script, which shows you the required system information every time you log into the shell.
|
||||
|
||||
There are six parts to this script, and more details below.
|
||||
|
||||
* **Part-1:** General System Information
|
||||
* **Part-2:** CPU/Memory Current Usage
|
||||
* **Part-3:** Disk Usage >80%
|
||||
* **Part-4:** List System WWN Details
|
||||
* **Part-5:** Oracle DB Instances
|
||||
* **Part-6:** Available Package Updates
|
||||
|
||||
|
||||
|
||||
We’ve added potential information to each area based on our needs. You can further customize this script to your needs if you wish.
|
||||
|
||||
There are many tools for this, most of which we have already covered.
|
||||
|
||||

### Bash Script to View System Information on Linux Every Time You Log into the Shell
|
||||
|
||||
This basic script will bring the system information to your terminal whenever you log into the shell.
|
||||
|
||||
```
|
||||
#vi /opt/scripts/system-info.sh
|
||||
|
||||
#!/bin/bash
|
||||
echo -e "-------------------------------System Information----------------------------"
|
||||
echo -e "Hostname:\t\t"`hostname`
|
||||
echo -e "uptime:\t\t\t"`uptime | awk '{print $3,$4}' | sed 's/,//'`
|
||||
echo -e "Manufacturer:\t\t"`cat /sys/class/dmi/id/chassis_vendor`
|
||||
echo -e "Product Name:\t\t"`cat /sys/class/dmi/id/product_name`
|
||||
echo -e "Version:\t\t"`cat /sys/class/dmi/id/product_version`
|
||||
echo -e "Serial Number:\t\t"`cat /sys/class/dmi/id/product_serial`
|
||||
echo -e "Machine Type:\t\t"`vserver=$(lscpu | grep Hypervisor | wc -l); if [ $vserver -gt 0 ]; then echo "VM"; else echo "Physical"; fi`
|
||||
echo -e "Operating System:\t"`hostnamectl | grep "Operating System" | cut -d ' ' -f5-`
|
||||
echo -e "Kernel:\t\t\t"`uname -r`
|
||||
echo -e "Architecture:\t\t"`arch`
|
||||
echo -e "Processor Name:\t\t"`awk -F':' '/^model name/ {print $2}' /proc/cpuinfo | uniq | sed -e 's/^[ \t]*//'`
|
||||
echo -e "Active User:\t\t"`w | cut -d ' ' -f1 | grep -v USER | xargs -n1`
|
||||
echo -e "System Main IP:\t\t"`hostname -I`
|
||||
echo ""
|
||||
echo -e "-------------------------------CPU/Memory Usage------------------------------"
|
||||
echo -e "Memory Usage:\t"`free | awk '/Mem/{printf("%.2f%"), $3/$2*100}'`
|
||||
echo -e "Swap Usage:\t"`free | awk '/Swap/{printf("%.2f%"), $3/$2*100}'`
|
||||
echo -e "CPU Usage:\t"`cat /proc/stat | awk '/cpu/{printf("%.2f%\n"), ($2+$4)*100/($2+$4+$5)}' | awk '{print $0}' | head -1`
|
||||
echo ""
|
||||
echo -e "-------------------------------Disk Usage >80%-------------------------------"
|
||||
df -Ph | sed s/%//g | awk '{ if($5 > 80) print $0;}'
|
||||
echo ""
|
||||
|
||||
echo -e "-------------------------------For WWN Details-------------------------------"
|
||||
vserver=$(lscpu | grep vendor | wc -l)
|
||||
if [ $vserver -gt 0 ]
|
||||
then
|
||||
echo "$(hostname) is a VM"
|
||||
else
|
||||
systool -c fc_host -v | egrep "(Class Device path | port_name |port_state)" > systool.out
|
||||
fi
|
||||
echo ""
|
||||
|
||||
echo -e "-------------------------------Oracle DB Instances---------------------------"
|
||||
if id oracle >/dev/null 2>&1; then
|
||||
/bin/ps -ef|grep pmon
|
||||
then
|
||||
else
|
||||
echo "oracle user does not exist on $(hostname)"
|
||||
fi
|
||||
echo ""
|
||||
|
||||
if (( $(cat /etc/*-release | grep -w "Oracle|Red Hat|CentOS|Fedora" | wc -l) > 0 ))
|
||||
then
|
||||
echo -e "-------------------------------Package Updates-------------------------------"
|
||||
yum updateinfo summary | grep 'Security|Bugfix|Enhancement'
|
||||
echo -e "-----------------------------------------------------------------------------"
|
||||
else
|
||||
echo -e "-------------------------------Package Updates-------------------------------"
|
||||
cat /var/lib/update-notifier/updates-available
|
||||
echo -e "-----------------------------------------------------------------------------"
|
||||
fi
|
||||
```
|
||||
|
||||
Once the above script is added to a file. Set the executable permission for the “system-info.sh” file.
|
||||
|
||||
```
|
||||
# chmod +x ~root/system-info.sh
|
||||
```
|
||||
|
||||
When the script is ready, add the file path at the end of the “.bash_profile” file in RHEL-based systems CentOS, Oracle Linux and Fedora.
|
||||
|
||||
```
|
||||
# echo "/root/system-info.sh" >> ~root/.bash_profile
|
||||
```
|
||||
|
||||
To take this change effect, run the following command.
|
||||
|
||||
```
|
||||
# source ~root/.bash_profile
|
||||
```
|
||||
|
||||
For Debian-based systems, you may need to add a file path to the “.profile” file.
|
||||
|
||||
```
|
||||
# echo "/root/system-info.sh" >> ~root/.profile
|
||||
```
|
||||
|
||||
Run the following command to take this change effect.
|
||||
|
||||
```
|
||||
# source ~root/.profile
|
||||
```
|
||||
|
||||
You may have seen an output like the one below when running the above “source” command.
|
||||
|
||||
From next time on-wards, you will get this information every time you log into the shell.
|
||||
|
||||
Alternatively, you can manually run this script at any time if you need to.
|
||||
|
||||
```
