My Bash scripting crash course

Bash scripting automates repetitive tasks.

Create a file called script.sh:

#!/bin/bash
echo "Hello World"

Make it executable:

chmod +x script.sh

Run it:

./script.sh

Variables:

name="Raheel"
echo $name

Conditionals:

if [ -f file.txt ]; then
echo "File exists"
fi

Loops:

for i in 1 2 3
do
echo $i
done

Bash scripting saves time and reduces manual errors.

Automate once. Run forever. Happy Bash scripting!
