Howto create a file
Hi folks,

How do we create a file using shell script?
i mean to say that do we use
is it a good approch to do
echo "abc" >file
echo "xxxx" >>file

or is there any better method?

Thanks,
Amit

try this

Code:
cat > 111

After this type text and press ^d to save a file.

Both approaches are correct what really matter is your choice.
you can create file using ">" operator and later you can append on same file with ">>" operator.

If you need a file with a certain size, use dd command or check the man pages depending on your needs.
The last thing I needed was to create 150GB file, I did it like that :
Code:
dd if=/dev/zero of=150g bs=1073741824 count=150
