Creating Command Prompt aliases and shortcuts Using Windows DOSKEY.

The following describes the steps to run a batch script that creates aliases using DOSKEY when opening command prompt. The batch file also creates an alias command that can be used to create aliases during the command line session.

Steps

1. Create a Batch file with the commands
2. Create shortcut that will run cmd with the batch file as input to the /k switch
   
   

Create a Batch file with the commands

• Open Notepad and copy the section between the markers and paste into notepad
  save the file to %USERPROFILE%\cmdrc.cmd
  ==== copy from @echo off to @echo on ====

  @echo off

  DOSKEY alias=if ".$*." == ".." ( DOSKEY /MACROS ) else ( DOSKEY $* )

  DOSKEY ls=DIR $* 

  DOSKEY cp=COPY $* 

  DOSKEY xcp=XCOPY $*

  DOSKEY mv=MOVE $* 

  DOSKEY clear=CLS

  DOSKEY h=DOSKEY /HISTORY

  DOSKEY history=DOSKEY /HISTORY

  ::compound commands

  set REPOS=%USERPROFILE%\Repos

  DOSKEY repos=cd /d %REPOS%$Tdir /a:d /b

  DOSKEY waffle=cd /d %REPOS%$Tdir /a:d /b$Tcd waffle$Tdir /a:d $Tgit branch

  DOSKEY bw=cd /d %REPOS%$Twaffle-build.cmd

  @echo on

  ==== copy from @echo off to @echo on ====

• Customise your shortcuts
• Place command separator as $T 
• when you edit the cmdrc.cmd file run it again
• %USERPROFILE%\cmdrc.cmd

Create a Shortcut to run the resource file

• Open Windows Explorer and create a New Shortcut
• Open the Shortcut Properties
• Select the General Tab and Name the Shortcut e.g.
• DosKey Alias - Command Prompt
  
  
  
  
  
  
• Select the Shortcut Tab and set the Target
• %windir%\system32\cmd.exe /k %USERPROFILE%\cmdrc.cmd
  

Tips on using the new alias batch file

Place command separator as $T in usual batch as an && or ||

This line "DOSKEY repos=cd /d %USERPROFILE%\repos$Tdir /a:d" in the batch below

In the command prompt window; the execution flow will result in the following when USERPROFILE is c:\users\myusername\repos

1. change to the device C:  

2. change to the directory to c:\users\myusername\repos

3. list directories only

Creating an alias 

while in the command prompt is opened using the Target as described above, you can create alias using the alias command.

alias lsb=DIR /b $*

Testing the new alias 

lsb c:\windows

Windows 10 Upgrade cheat sheet

Decide if you want Windows 10 32-bt or 64-bit
64-Bit if you want to be able to nearly run ALL software available, both 32-bit and 64-bit software
32-Bit if you only want to be able to run 32-bit software
If you don't have an OS on the Device, You'll need another Device for the Installation Media Download

Use a 32GB Flashdrive 
 Follow the steps in the follow link: http://www.microsoft.com/en-gb/windows/windows-10-upgrade
Click Get Started
Download GWXWebWindows.exe to your Device
On your Device, click GWXWebWindows.exe
Follow this page: https://www.microsoft.com/en-gb/software-download/windows1
Click whichever installation you want on your Device

Download Tool Now (32-bit version)

downloads the file named: MediaCreationTool.exe

Download Tool Now (64-bit version)

ORACLE: Database Links

Creating a Database Link

create database link [LINK_NAME] connect to [USER_ID] identified by [PASSWORD] using '[TNS_NAME]';

example

RDB=((DESCRIPTION...)

create database link RDB_LINK connect to RDB identified by RDB_USER using 'RDB';

ORACLE: Generating CSV output

CSV output to file

set linesize 130

set pagesize 0

set echo off

set wrap off

set heading off

-- get databases users

-- output to file in the same directory as where you have opened SQL*Plus

spool database_users.csv

select u.user_id || ',' || u.surname || ',' || u.forenames

from user u,

where LOWER(u.user_id) like '%a%'

BASH - Archiving Directories

Archive Directories

#!/bin/bash

# Loop through all directories within the current directory
# tar and gzip all files into a single tarball file
for dir in *
do
    if [ -d "${dir}" ] then
        echo "archiving ${dir} with tar -zcvf"
        echo "tar -zcvf \"${dir}\".tar.gz \"${dir}\""
        dest=`echo ${dir} | tr -t '[ ]' '[_]'`
        echo "dest is now ${dest}"
        tar -zcvf "${dest}".tar.gz "${dir}"
        rm -rf "${dir}"

Perl RegEx: Updating files

Using the Perl Interpreter to update a single file

perl -p -i -e 's{^([^\b\w\t]*)(.*)(openApplication)([^>]*)(.*) Form Menu(.*)$}{\1\2\3\4}' $APACHE_DOCS/$APP_URI/index.html



Using xargs to pass command line parameters to perl

cd /usr/local/adobe/central/

egrep -ir csr00001 * | cut -d: -f1 | xargs perl -p -i -e 's/csr00001/$ENV{HOSTNAME##.*}/g'

Some Crypto in Anger - using JCE and BouncyCastle JCE Provider

OutputStream out = new ObjectOutputStream(new FileOutputStream("encrypter.key"));

// Serialize the secret to a byte array

ByteArrayOutputStream bos = new ByteArrayOutputStream();

ObjectOutput objectOutput = new ObjectOutputStream(bos);
 objectOutput.writeObject(secret);

objectOutput.close();

// Get the bytes of the serialized object and use them as the inputstream

InputStream is = new ByteArrayInputStream(bos.toByteArray());
streamEncrypter.encrypt(is, out);
