Result
#!/bin/bash
echo "-----------DAY 5------------"
day=$(date)
greet="Welcome to BuildingTHEITGUY"
echo "$day"
echo "$greet"
echo "Topic - Installing Apps from Script"
echo '###Checking Update..'
apt-get update # To get the latest package lists
echo '###Installing Toilet..'
apt-get install toilet -y
echo "---------xxxxxx--------------"
DAY 4
In this script, we call about the system full IP information IPv4 and IPv6 also called in Linux inet for IPV4 and inet6 IPV6, once we call this information we can filter this by grep command like match certain keyword in this output.
#!/bin/bash
echo "-----------DAY 1------------"
day=$(date)
ip=$(ip a | grep inet)
greet="Welcome to BuildingTHEITGUY"
echo "$day"
echo "$greet"
echo "Topic - Getting INFO"
echo "---------xxxxxx--------------"
echo "$ip"
echo "--------STAY TUNE------------"
DAY 4DAY 3
#!/bin/bash
echo "-------------DAY 3---------------"
day=$(date)
linver=$(lsb_release -a | grep Release)
size=$(free -h)
echo "CURRENT VERSION $linver"
echo "SERVER INFO $size"
echo "--------STAY TUNE------------"
DAY 2
If you learn or see the bash script first time, you can notice the first line of the script starts with #! Its called SHEBANG #!
which used tell the Linux OS, which interpreter to use to parse the rest of the file.
Today Hint – We will find the version as output using $(command)
#!/bin/bash
echo "-----------DAY 2-------------"
day=$(date)
linver=$(lsb_release -a)
echo "DAY 2 $day"
echo "Topic - Version"
echo "My Bash Version is $BASH_VERSION"
echo "My linux Version is $linver"
echo "---------STAY TUNE----------"
DAY 1
Bash or Shell, whatever we call it can do magic, it can be a text file containing a series of commands and just give the output, what you want.
Today Hint – Echo in bash used to throw the output.
#!/bin/bash
echo "------------DAY 1--------------"
day=$(date)
greet="Welcome to BuildingTHEITGUY"
echo "$day"
echo "Topic - ECHO"
echo "$greet"
echo "---------STAY TUNE-------------"
