I am looking to write the output of
cat /var/log/dpkg.log
to a file rather than viewing on the screen.
I have tried
cat /var/log/dpkg.log | file.txt
without any success.
Ultimately I want this command and
dmesg -T
to run automatically from a batch from a usb.
The usb has the "ID" of 0782:5551. Is it possible to get the "file.txt" (with the date and time included in filename) to be written to that same USB drive via it's "ID" since it could any "device' depending on its order?
The purpose of this is for a project to ultimately compare the file based on dates.

You seem to have 3 questions here: how to re-direct stdout, how to address a usb storage device, howe to put a date in a file-name. (We have a one question per question policy. But as many questions as you like.)

Indeed. Also, one usually writes files to the mounted filesystem, not to the device file itself. So it would bedmesg -T > /media/mounpoint/$(date +%Y%m%d%a%H%M).log. Auto-generated mount-points rely on partition IDs or labels and thus are usually stable.

$(date...) works perfectly, thanks.
If I can write to the same drive as where the bash was fun from that would be great.
