Check These Out
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
If you are stuck behind a firewall and want to synchronize time with another server but you do not want to port forward NTP (which uses UDP) then this command is handy. It gets the time from a server and sets the local time. It is not that accurate but I can live with a second or so drift.
-k (kill option ) . To kill all processes accessing this port
The biggest advantage of this over the functions is that it is portable.
The solution to a year long (and extremely frustrating) problem I've had, caused by the fact that I only have one speaker; this command downmixes the stream to monophonic output, making sure I don't miss any of the music.
NOTE: When stream is in .m3u format, a -playlist option is required, as shown below:
$ mplayer -af pan=1:0.5:0.5 -channels 1 -playlist radiostream.m3u
This command works great with aliases for various channels in .bashrc. Sample below:
$ alias radio1='mplayer -af pan=1:0.5:0.5 -channels 1 radio1stream.pls'

-C is for compression.

Summarize established connections after netstat output.
Using tee and /dev/stderr you can send one command output to terminal before executing wc so you can summarize at the bottom of the output.
