doing they other way is faster IDK HOW chatgpt said show'd me that code i tested it was much faster printf '%s\n' {0..250},.{0..10},.{0..10},.{0..10}, > >(cat > out1.txt) but then i changed it to this printf '%s\n' {0..250},.{0..250},.{0..10},.{0..10}, > >(cat > out1.txt) they second 0..10 to 0..250 and damn it failed to work XD
Why are you using cat here? Just directly write to the file.
