Show progress during dd copy

Ok, this is actually a copy and paste post thus credit is due where credit is deserved: Linux Commando.

The quick-and-dirty trick: open a new terminal and enter:

$ kill -INFO <PID of dd process>

NOTE: do not use USR1 on Mac OS X!

The “output” will be printed on the console where dd is actually running:

$ dd if=/path/to/file of=/dev/sdb1 bs=1M
0+14 records in
0+14 records out
204 bytes (204 B) copied, 24.92 seconds, 0.0 kB/s

[131028 update]: in fact $ sudo pkill -INFO -n -x dd seems to be a much quicker, and easy to remember, one-liner.

List all files in a directory, order by date

Nothing original, the Internet is full of good recommendations, but I had to come up with my own answer:

cd to the upper-level directory
run: find . -type f -print0 | xargs -0 ls -rtl | awk '{print $6 " " $7 " " $8 " " $9}'

Explanation:

find recursively looks for regular files starting from the current directory, output is a long uninterrupted list
xargs is used to pass the above output to ls which will display in reverse order, by time, in long format
awk will select only the relevant fields
