Check These Out
Your platform may not have pv by default. If you are using Homebew on OSX, simply 'brew install pv'.
If you want to check that the spoof worked, type the same command as earlier:
$ifconfig en1 | grep ether
Now you will see:
$ether 00:e2:e3:e4:e5:e6
For the wired ethernet port:
$sudo ifconfig en0 ether 00:e2:e3:e4:e5:e6
More recent versions of the date command finally have the ability to decode the unix epoch time into a human readable date. This function makes it simple to utilize this feature quickly.
Converts any number of seconds into days, hours, minutes and seconds.
sec2dhms() {
declare -i SS="$1"
D=$(( SS / 86400 ))
H=$(( SS % 86400 / 3600 ))
M=$(( SS % 3600 / 60 ))
S=$(( SS % 60 ))
[ "$D" -gt 0 ] && echo -n "${D}:"
[ "$H" -gt 0 ] && printf "%02g:" "$H"
printf "%02g:%02g\n" "$M" "$S"
}
The command (above) will remove any duplicate rows based on the FIRST column of data in an un-sorted file.
The '$1' represents a positional parameter. You can change both instances of '$1' in the command to remove duplicates based on a different column, for instance, the third:
$ awk '{ if ($3 in stored_lines) x=1; else print; stored_lines[$3]=1 }' infile.txt > outfile.txt
Or you can change it to '$0' to base the removal on the whole row:
$ awk '{ if ($0 in stored_lines) x=1; else print; stored_lines[$0]=1 }' infile.txt > outfile.txt
** Note: I wouldn't use this on a MASSIVE file, unless you're RAM-rich ;) **
The above command will open a Remote Desktop connection from command line, authenticate using default username and password (great for virtual machines; in the exampe above it's administrator:password), create a shared folder between your machine and the other machine and configure resolution to best fit your desktop (I don't like full screen because it make the desktop panels to disappear). The command will run in the background, and expect to receive parameters. You should enter hostname or IP address as a parameter to the command, and can also override the defaults parameters with your own.
