Insert text into a file using shell script
Hi,

I need to insert "Hello World" text into a file called hai.txt using shell scripting. Kindly help me.

For eg: If I open the file hai.txt by giving linux command cat hai.txt, the content of the file should have the text Hello World in it.

Thanks

You can redirect the output of echo to file.
Code:
echo "Hello world." > Hi.txt

for creating new file/overriding data into file
Code:
echo "Hello World" > hai.txt

for appending data into file
Code:
echo "Hello World" >> hai.txt
