Intro

TCL-Expect scripts are an amazingly easy way to script out laborious tasks in the shell when you need to be interactive with the console. Think of them as a "macro" or way to programmaticly step through a process you would run by hand. They are similar to shell scripts but utilize the .tcl extension and a different #! call.

Setup Your Script

The first step, similar to writing a bash script, is to tell the script what it's executing under. For expect we use the following:

#!/usr/bin/expect

A definitive guide for installing Apache-httpd server without root privileges | Only for unix-like systems

During the work of my thesis I had to run php based applications on a linux server where I had no root privileges. Hence I dug up on the web and I present to you

a way to install apache httpd at any desired location.

./configure --enable-file-cache --enable-cache --enable-disk-cache --enable-mem-cache 
--enable-deflate --enable-expires --enable-headers --enable-usertrack 
--enable-cgi --enable-rewrite --enable-so --enable-vhost-alias  
--with-apr=/home/nisal/apache/httpd-2.4.17/srclib/apr-1.5.2/ --with-apr-util=/home/nisal/apache/httpd-2.4.17/srclib/apr-util-1.5.4/ 
--prefix=/home/nisal/apache/httpd-2.4.17/

##Git commands I encountered throughout my git-experience

####Best Git practices

1. Always review what's in the staging area before commiting to make sure you would only add/commit whats intended to be committed -> Saves you from pushing undesired objects to remote.

git status | git diff --cached

2. Always fetch from remote before working in order to avoid (future) conflicts ####Regular git workflow for creating/adding/committing/pushing new files to (remote) repository
