Using this command you can track a moment when usb device was attached.
if you don't want to show string "version?, then use awk or cut filter it: apt-cache show pkgname | grep -i "version:" | awk '{ print $2 }'
we can also use regex to search many packages and show their versions:
apt-cache search pkgregex | grep -i "version:"
curl inet-ip.info -> 113.33.232.62\n
curl inet-ip.info/ip -> 113.33.232.62
curl inet-ip.info/json -> JSON print
curl inet-ip.info/json/indent -> JSON pretty print

You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token.
This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use:
`awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'`
You must adapt the command line to include:
* $MFA_IDis ARN of the virtual MFA or serial number of the physical one
* TTL for the credentials

Looks up a word on merriam-webster.com, does a screen scrape for the FIRST audio pronunciation and plays it.
USAGE: Put this one-liner into a shell script (e.g., ~/bin/pronounce) and run it from the command line giving it the word to say:
$ pronounce lek
If the word isn't found in merriam-webster, no audio is played and the script returns an error value. However, M-W is a fairly complete dictionary (better than howjsay.com which won't let you hear how to pronounce naughty words).
ASSUMPTIONS: GNU's sed (which supports -r for extended regular expressions) and Linux's aplay. Aplay can be replaced by any program that can play .WAV files from stdin.
KNOWN BUGS: only the FIRST pronunciation is played, which is problematic if you wanted a particular form (plural, adjectival, etc) of the word. For example, if you run this:
$ pronounce onomatopoetic
you'll hear a voice saying "onomatopoeia".
Playing the correct form of the word is possible, but doing so might make the screen scraper even more fragile than it already is. (The slightest change to the format of m-w.com could break it).
Sends the "USR1" signal every 1 second (-n 1) to a process called exactly "dd".
The signal in some systems can be INFO or SIGINFO ...
look at the signals list in: man kill
