I have a directory dash7/
which contains multiple text files and I want to remove all lines containing the string D PRINT
from all those files.
How can I do that easily from the command-line?

You can achieve this rather easily with sed
which can happily look into multiple files
sed '/D PRINT/d' dash7/*
/D PRINT/
find a line with D PRINT
d
delete the linedash7/*
look in all the files in the directory dash7
(add the path to it, for example ~/dash7
if required)To actually change the files rather than print the edited text in the terminal, you need to add the -i
flag to modify in place
sed -i '/D PRINT/d' dash7/*
