Here in this article i am going to mentions a small script to convert octal number to decimal numbers. We are going to test this script in linux.I have tested it on RedHat Linux.
In this article I we will use (()) and bc commands to do my task.
You may be excited to know that there are several tips and tricks to do that and here i am going to mention all those.
Trick1: Use (()) brace expatiation.
Here I am going to create a file octa.sh using vim editor. and write the below code.
#!/bin/bash
read -p “enter OCT number: ” OCT1
echo “The decimal value of $HEX1 is $((8#$HEX1))”
Now Change permissions of script:
chmod +x octa.sh
Now run the shell script
#./octa.sh
Trick2: Using bc command
#!/bin/bash
read -p ” enter OCT number: ” OCT1
echo “ibase=8; $OCT1” | bc
Save above file as octatodec.sh
Change permissions to this script now and execute as follows
chmod +x octatodec.sh
Executing shell script
./oct2dec.sh
