Execute MySql script from the command line

Leave a comment

This tip is very similar to how to “Execute a SQL file via the MySQL command line in one line” only this time specifying the DB you want to execute the script against and being prompted for your password…

mysql -u user -p -h localhost MyDb < ~/SQL/script.sql

Using sed to view and replace text on a specific file in Linux

Leave a comment

Ever need to replace very specific text on a particular line in a very large file on Linux? Enter the sed command.

To view the line (let’s say line 864 in this case) in the specific file, issue this command…

$ sed -n '864'p myfile.txt

And let’s say you get back the string ” I hate cheese”. Since we all know that’s not true, you can use a different variation of the sed command to replace “hate” with “love” like so…

$ sed -i '864s/hate/love/' myfile.txt

And if you’re really curious on how this even came about, it was due to an error in the phpMyAdmin export.php script when you had to change “break 2” to “break” on line 846 as identified here: https://askubuntu.com/questions/928883/500-error-on-phpmyadmin-export-on-phpmyadmin-export-php/930975

Scary Chip Flaws Raise Spectre of Meltdown — Krebs on Security

Please be sure to update/patch every device you have. On most Windows machines, you should be able to do a manual reboot (Start -> Power -> Restart) and have the updates applied. On iOS you want to go to Settings -> General -> Software Update

The Most Dangerous Thing You Can Do While “Multitasking”

Leave a comment

So true. Please enable “DND while driving” on your phone! Both the iPhone and Android have the feature. I’ve been using it since I updated to iOS 11, and it works well. Just getting the notifications I found was a distraction, and since I can still get calls from my “favorites” it’s been a huge help.

Want to receive an email any time your linux server reboots? Just create this script…

sudo nano /usr/local/sbin/startupemail.sh

Here’s the code for the script…

#!/bin/sh

# Lets things startup
sleep 60

# Get info
IP="$(ifconfig | grep -A 1 'eth0' | tail -1 | cut -d ':' -f 2 | cut -d ' ' -f 1)"
HOSTNAME=`hostname`

#Send email
echo "IP: $IP, Host: $HOSTNAME" | mail -s "Server Started" [email protected]

Make sure to make it executable…

sudo chmod u+x /usr/local/sbin/startupemail.sh

Then add it to your /etc/rc.local file

Find the Members of an Active Directory Group

Leave a comment

The simplest way to get the list of users in an Active Directory group is to use the following command right from the command line:

NET GROUP "my_group" /DOMAIN

And yes, that is the work “DOMAIN”, not the domain you are in. The only value to change in the command is my_group

Ref: Is there a way to view the members of an Active Directory group if you aren’t a domain admin and can’t log into a domain controller?
