Get primary IP of the local machine

Plenty of commands out there for finding external IP, but sometimes getting the [internal] IP bound to the NIC handling Internet traffic is useful. Probably not production worthy, but a useful quick kludge. Assumes IPv4 and no fancy routing. Show Sample Output

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

How to backup hard disk timely?

'data' is the directory to backup, 'backup' is directory to store snapshots. Backup files on a regular basis using hard links. Very efficient, quick. Backup data is directly available. Same as explained here : http://blog.interlinked.org/tutorials/rsync_time_machine.html in one line. Using du to check the size of your backups, the first backup counts for all the space, and other backups only files that have changed.

Store dirs to later be changed to independant of the last directory you were in. Also with managment tools.

Check out: help dirs help pushd help popd -- Cheers!
