Bash shortcuts from PUTTY

Ctlr + A - go to the beginning of line

Ctrl + E - go to the end of line

Ctrl + W - delete a word

Alt + f - Move forward

Alt + B - move backwords

Alt + BackSpace - Delete backward from cursor

down arrow - browser command history backwords

up arrow - browse command history upwards

Ctrl + r - Recall command

Ctrl + z - Suspend/ Stop the command

Search the history backwards

Ctrl + l - clear the screen



Here "2T" means Press TAB twice

$ 2T - All available commands(common)
$ (string)2T - All available commands starting with (string)
$ /2T - Entire directory structure including Hidden one

alternative of net use command on the cmd prompt on Windows

Open a Command Prompt window.
Type the following command line:
PUSHD ServerSharepath

where \\Server\Share\path is the network resource to which you want to map a drive letter.

As soon as you do, the PUSHD command will instantly map a drive letter to the network resource and then change to that drive right in the Command Prompt window. When you’re done, just type POPD and the mapped drive letter will be disconnected and you’ll return to your original drive.

Keep in mind that, the PUSHD command allocates drive letters from Z: on down and will use the first unused drive letter that it finds.

what was the point of the previous one

well to have the best possible format for your history - html ; )

perl /usr/bin/parseHistoryFile.pl --verbose --html /home/$USER/.mozilla/firefox/8sllsdks.default/history.dat > /var/www/tmp.html

Note - the 8sllsdks.default is something else on your system
and you would have to replace $USER with your user name

parse automatically firefox history file

#
# This is a program that can read the Mozilla URL history file --
# normally $HOME/.mozilla/default/*.slt/history.dat -- and prints out
# a list of URLs and their time of last access. With no arguments,
# it prints lines like
#
# 1078333826 1 http://www.jwz.org/hacks/
#
# where the first number is a ctime (number of seconds since Jan 1 1970 GMT)
# and the second number is how many times this URL was visited. The URLs are
# printed most-recent-first.
#
# With -vv, it prints all the information known about each URL,
# including time of first visit, last visit, document title, etc.
#
# With --html, it produces HTML output instead of plain text.
#
# With "--age 2H", it limits itself to URLs that were loaded within the
# last two hours. Likewise with "sec", "min", "day", "month", etc.
#
##############################################################################
#
# And Now, The Ugly Truth Laid Bare:
#
# In Netscape Navigator 1.0 through 4.0, the history.db file was just a
# Berkeley DBM file. You could trivially bind to it from Perl, and
# pull out the URLs and last-access time. In Mozilla, this has been
# replaced with a "Mork" database for which no tools exist.
#
# Let me make it clear that McCusker is a complete barking lunatic.
# This is just about the stupidest file format I've ever seen.
#
# http://www.mozilla.org/mailnews/arch/mork/primer.txt

# http://www.jwz.org/doc/mailsum.html
# http://bugzilla.mozilla.org/show_bug.cgi?id=241438
#
# In brief, let's count its sins:
#
# - Two different numerical namespaces that overlap.
#
# - It can't decide what kind of character-quoting syntax to use:
# Backslash? Hex encoding with dollar-sign?
#
# - C++ line comments are allowed sometimes, but sometimes // is just
# a pair of characters in a URL.
#
# - It goes to all this serious compression effort (two different
# string-interning hash tables) and then writes out Unicode strings
# without using UTF-8: writes out the unpacked wchar_t characters!
#
# - Worse, it hex-encodes each wchar_t with a 3-byte encoding,
# meaning the file size will be 3x or 6x (depending on whether
# whchar_t is 2 bytes or 4 bytes.)
#
# - It masquerades as a "textual" file format when in fact it's just
# another binary-blob file, except that it represents all its magic
# numbers in ASCII. It's not human-readable, it's not hand-editable,
# so the only benefit there is to the fact that it uses short lines
# and doesn't use binary characters is that it makes the file bigger.
# Oh wait, my mistake, that isn't actually a benefit at all.
#
# Pure comedy.

193 - install mysql
194
195 - configure mysql - add users , create databases on mysql
196
197 - configure Apache
198
199 - install myPhpAdmin
200
201 - configure myPhpAdmin
202
203
204
205 1.Install Apache
206
207 #INSTALL APACHE
208

216 #install PHP mod_php for Apache
217 sudo apt-get install php5 libapache2-mod-php5
218
219 echo '
<?php echo "Haaudi World"; ?>' > /var/www/test.php
220 open http://localhost/test.php - > you should see Haudi World
221
222 2. Install mySQL
223
224 #if installation of previous packages has failed
225
226 dpkg --configure -a
227 sudo /etc/init.d/apache2 stop | start | restart
228
229 #install mysql server
230 sudo apt-get install mysql-server
231 #when prompted type in your password
232
233 #if not prompted the command to get to the mysql prompt is :
234
235 mysql -uroot -pmysql
236
237 #set the password with the following:
238 mysql> SET PASSWORD FOR '
root'@'localhost' = PASSWORD('SecretPass');
239 #run the mysql with:
240 mysql -uroot -pSecretPass
241
242 #view the databases
243
244 show databases ;
245
246 #create a database with one table
247
248 create database testdb ;
249
250 use db_test
251
252 CREATE TABLE tb_testtable(
253 column0 INT PRIMARY KEY AUTO_INCREMENT,
254 column1 VARCHAR(100),
255 column2 VARCHAR(10) ) TYPE=INNODB;
256
257 3. Intall php
258
259 #install the php admin
260 sudo apt-get install libapache2-mod-auth-mysql php5-mysql
261 #when prompted configure the type of servers
262
263 #Other php modules usefull for development
264 apt-get install php5-gd
265 apt-get install php5-ldap
266 apt-get install php5-mysql
267 apt-get install php5-openssl
268 apt-get install php5-pear
269
270 4. Install phpMyAdmin
271
272 Download the latest stable build of phpMyAdmin [[http://surfnet.dl.sourceforge.net/sourceforge/phpmyadmin/phpMyAdmin-2.11.3-all-languages.tar.bz2]]
273
274 #place the tar under a phpMyAdmin folder (you would have to create it mkdir /var/www/phpMyAdmin ) under your doc root folder
275
276 mv /home/user/downloads/phpMyAdmin-2.11.3-all-languages/ /var/www/phpMyAdmin
277
278 tar -xvf phpMyAdmin-2.11.3-all-languages.tar.bz2
279
280 #configure the most sipliest (not sucure !!!) setup
281

292 $i++;
293 $cfg['
Servers'][$i]['auth_type'] = 'cookie';
294 ?>
