Running MySQL *.sql files in PHP Ask Question
Saved by uncleflo on February 15th, 2018.
I have two *.sql files that I use when creating a new web site database. The first file creates all the tables. The second file populates some default records. I would like to execute these files from PHP. I also use the Zend_Framework, if that will help accomplish this? Answer: This question comes up from time to time. There's no good solution for running a .sql script directly from PHP. There are edge cases where statements common in a .sql script can't be executed as SQL statements. For example, the mysql tool has builtin commands that are not recognized by the MySQL Server, e.g. CONNECT, USE, and DELIMITER.

Which characters need to be escaped in Bash? How do we know it?
Saved by uncleflo on February 7th, 2018.
Is there any comprehensive list of characters that need to be escaped in Bash? Can it be checked just with sed? In particular, I was checking whether % needs to be escaped or not. I tried this and worked fine, without escaping %. Does it mean % does not need to be escaped? Was this a good way to check the necessity? And more general: are they the same characters to escape in shell and bash?

How to Read a File Line by Line in a Shell Script
Saved by uncleflo on January 27th, 2017.
There are many ways to handle any task on a Unix platform, but some techniques that are used to process a file waste a lot of CPU time. Most of the wasted time is spent in unnecessary variable assignment and continuously opening and closing the same file over and over. Using a pipe also has a negative impact on the timing. In this article I will explain various techniques for parsing a file line by line. Some techniques are very fast and some make you wait for half a day. The techniques used in this article are measurable, and I tested each technique with time command so that you can see which techniques suits your needs.

Advanced Bash-Scripting Guide
Saved by uncleflo on October 28th, 2016.
This tutorial assumes no previous knowledge of scripting or programming, yet progresses rapidly toward an intermediate/advanced level of instruction... all the while sneaking in little nuggets of UNIX® wisdom and lore. It serves as a textbook, a manual for self-study, and as a reference and source of knowledge on shell scripting techniques. The exercises and heavily-commented examples invite active reader participation, under the premise that the only way to really learn scripting is to write scripts. This book is suitable for classroom use as a general introduction to programming concepts. This document is herewith granted to the Public Domain. No copyright!

GNU Parallel - GNU Project - Free Software Foundation
Saved by uncleflo on August 9th, 2014.
GNU Parallel For people who live life in the parallel lane. GNU parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU parallel can then split the input and pipe it into commands in parallel.

A shell script is a sequence of commands for which you have a repeated use. This sequence is typically executed by entering the name of the script on the command line. Alternatively, you can use scripts to automate tasks using the cron facility. Another use for scripts is in the UNIX boot and shutdown procedure, where operation of daemons and services are defined in init scripts. To create a shell script, open a new empty file in your editor. Any text editor will do: vim, emacs, gedit, dtpad et cetera are all valid. You might want to chose a more advanced editor like vim or emacs, however, because these can be configured to recognize shell and Bash syntax and can be a great help in preventing those errors that beginners frequently make, such as forgetting brackets and semi-colons.

HowTos/Network/SecuringSSH - CentOS Wiki
Saved by uncleflo on September 12th, 2013.
OpenSSH (or Secure SHell) has become a de facto standard for remote access replacing the telnet protocol. SSH has made protocols such as telnet redundant due, in most part, to the fact that the connection is encrypted and passwords are no longer sent in plain text for all to see. However, a default installation of ssh isn't perfect, and when running an ssh server there are a few simple steps that can dramatically harden an installation.

dd - writing zeros - general question
Saved by uncleflo on August 23rd, 2013.
Can't figure out why using dd to write zeros to a hard drive is so slow. Yesterday, I prepped a hard drive for a friend and did the standard command: dd if=/dev/zero of=/dev/sda The machine I used has a Core 2 Duo 2.4 Ghz cpu, 2 Gigs of DDR2 800 RAM, a new Intel mobo, and a Western Digital 250 gig. SATA drive with 16 meg. cache. The result was 30,482 seconds (approx. 8.5 hrs.) to write zeros to the entire 500 Gig. drive, at an average rate of 16.4 MB/sec.

Ubuntu Linux: How do I install .deb packages?
Saved by uncleflo on September 6th, 2011.
I am a new Ubuntu Linux use. I need to install a package called package.deb. I know I can use Synaptic package management to install packages from CD or Internet. But I want to install this special .deb file. So how can I install package? You need to use dpkg package manager from shell/command prompt. dpkg is a tool to install, build, remove and manage packages. dpkg itself is controlled entirely via command line parameters. For example -i use to install .deb file. How do I install .deb file? To install package called package.deb type the following command:

Installing .deb package through the terminal - Ubuntu Forums
Saved by uncleflo on March 9th, 2011.
How do I install a .deb package through the terminal because I can't use the GDebi Package installer because I get an error of corruption or permission. The package is on the my desktop and I would like to install it to /home/thieflock/appearance/kiba dock so what would that command line be? - If there is a problem installing with Gdebi, maybe you should try downloading it again.
