I'm learning SED command. And while doing that i got to this place where i'm taking a copy of my existing file. The code i used is -
As expected, the file 'books.txt' is read , and lines with 'Storm' is put in to the new file 'Storm.txt'. However, it also throws the below error -
sed: read error: Bad file descriptor
Can someone help me understand why is it happening.
