Using this command you can track a moment when usb device was attached.

sort is way slow by default. This tells sort to use a buffer equal to half of the available free memory. It also will use multiple process for the sort equal to the number of cpus on your machine (if greater than 1). For me, it is magnitudes faster.
If you put this in your bash_profile or startup file, it will be set correctly when bash is started.
$ sort -S1 --parallel=2 /dev/null && alias sortfast='sort -S$(($(sed '\''/MemF/!d;s/[^0-9]*//g'\'' /proc/meminfo)/2048)) $([ `nproc` -gt 1 ]&&echo -n --parallel=`nproc`)'
Alternative
$ echo|sort -S10M --parallel=2 &>/dev/null && alias sortfast="command sort -S$(($(sed '/MemT/!d;s/[^0-9]*//g' /proc/meminfo)/1024-200)) --parallel=$(($(command grep -c ^proc /proc/cpuinfo)*2))"
# find assumes email files start with a number 1-9
# sed joins the lines starting with " " to the previous line
# gawk print the received and from lines
# sort according to the second field (received+from)
# uniq print the duplicated filename
# a message is viewed as duplicate if it is received at the same time as another message, and from the same person.
The command was intended to be run under cron. If run in a terminal, mutt can be used:
mutt -e "push otD~=xq" -f $folder
Using awk, find duplicates in a file without sorting, which reorders the contents. awk will not reorder them, and still find and remove duplicates which you can then redirect into another file.
This is a quick and easy way of encrypting files in a datastream, without ever really creating an output file from gpg. Useful with cron also, when file(s) have to be sent based on a set schedule.
This is a beginning script. You can create a file with > filename. You can also use diff to compare output run at different times to verify no change in your files. I apologize in advance if this is too simple. For some it should be a start.
