deleting a line but keeping the same file
Hi,

I want to delete a line in a file that contains a string. I tried:
grep -v "mystring" Myfile > Myfile

But this makes the Myfile empty. I read that I need to do something like:
grep -v "mystring" Myfile > Myfile.new
rm Myfile
mv Myfile.new Myfile

Is there a way to avoid creating a temporary file??

Thanks in advance.

Hi Laiko,


There is no such way.


Regards,
Vinod.

If you have GNU sed, which supports "-i" option, you can use:

Code:
sed -i "/mystring/d" Myfile
