SQL*Plus command line history completion - RLWRAP
Doc ID: 460591.1
Purpose

The SQL*Plus, the primary interface to the Oracle Database server, 
provides a powerful yet easy-to-use environment for querying, defining, and controlling data.
However, some command-line utilities, for example bash, provide features such as:

- command history (up/down arrow keys)
- auto completion (TAB key)
- searchable command line history (Ctrl+r)

The scope of this bulletin is to provide these features to SQL*Plus.

Scope and Application

For all SQL*Plus users, but in particular for Linux platforms as this note has been written thinking at that Operating System. In any case this idea can work on other OSs as well.
SQL*Plus command line history completion

SQL*Plus users working on Linux platforms have the opportunity to use a readline wrapper "rlwrap". rlwrap is a 'readline wrapper' that uses the GNU readline library to allow the editing of keyboard input for any other command. Input history is remembered across invocations, separately for each command; history completion and search work as in bash and completion word lists can be specified on the command line. Since SQL*Plus is not built with readline library, rlwrap is just doing the job.

- 'rlwrap' is really a tiny program. It's about 24K in size, and you can download it from the official developper (Hans Lub) website http://utopia.knoware.nl/~hlub/uck/rlwrap/

What do you need to compile and run it
A newer (4.2+) GNU readline (you can get it at ftp://ftp.gnu.org/gnu/readline/)
and an ANSI C compiler. 
rlwrap compiles and runs on many Unix systems and on cygwin.

Installation should be as simple as:

./configure
make
make install
 

Compile rlwrap statically

If you don't have the root account you can compile rlwrap statically
and install it under $HOME/bin executing this command:

CFLAGS=-I$HOME/readline-6.0 CPPFLAGS=-I$HOME/readline-6.0 LDFLAGS=-static ./configure --prefix=$HOME/bin
make
make install

where $HOME/readline-6.0 is the 'readline' source location

 



A different option and if your are using Linux, it is to download the newest source rpm package from e.g.: http://download.fedora.redhat.com/pub/epel/5/SRPMS/rlwrap-0.37-1.el5.src.rpm and build the binary rpm package by

# rpm -ivh rlwrap-0.37-1.el5.src.rpm
# cd /usr/src/redhat/SPECS/
# rpmbuild -bb rlwrap.spec
# cd ../RPMS/<arch>/
and then you can install it as any other rpm package by e.g.

# rpm -ivh rlwrap-0.37-1.x86_64.rpm
 

- After installing the package, you should to configure a user's environment so that it makes use of the installed utility, add the following line in '/etc/bashrc' (globally) or in '${HOME}/.bashrc' (locally for the user). Change '<path>' with the right path of your rlwrap:

alias sqlplus='<path>/rlwrap ${ORACLE_HOME}/bin/sqlplus'
The modified .bashrc won't take effect until you launch a new terminal session or until you source .bashrc. So shut down any terminals you already have open and start a new one.

If you now launch SQL*Plus in exactly the way you've used so far, you should be able to type one SQL command and submit it, and then immediately be able to press the up-arrow key and retrieve it. The more SQL commands you issue over time, the more commands rlwrap will remember. As well as just scrolling through your previous SQL commands, you can press 'Ctrl+r' to give you a searchable command line history.


You can also create your own '${HOME}/.sqlplus_completions' file (locally)or '/usr/share/rlwrap/sqlplus' file (globally) with all SQL reserved words (or in case whatever you want) as your auto-completion list (see rlwrap man page for dettails).

And example of '${HOME}/.sqlplus_completions' with some reserved words:

 

COPY PAUSE SHUTDOWN 
DEFINE PRINT SPOOL 
DEL PROMPT SQLPLUS 
ACCEPT DESCRIBE QUIT START 
APPEND DISCONNECT RECOVER STARTUP

Note: 
You can use 'rlwrap' with all Oracle command line utilities such as Recovery Manager (RMAN) , Oracle Data Pump (expdp), ASM command (asmcmd), etc. 

i.e.: 


alias rman='/usr/bin/rlwrap ${ORACLE_HOME}/bin/rman' 
alias expdp='/usr/bin/rlwrap ${ORACLE_HOME}/bin/expdp'
alias asmcmd='/usr/bin/rlwrap ${ORACLE_HOME}/bin/asmcmd'

HOWTO - general workflow




Basic commands and getting started

Git Data Flow
1) Current Working Directory	<-- git init <project>
2) Index (cache)				<-- git add .
3) Local Repository				<-- git commit -m "<comment>"
4) Remote Repository

Client side setup
http://git-scm.com/downloads   <-- download here 

git config --global user.name "karlarao"
git config --global user.email "karlarao@gmail.com"

Common commands
git init awrscripts				<-- or you can just cd on "awrscripts" folder and execute "git init"
git status
git add . 						<-- add all the files under the master folder to the staging area
git <filename>					<-- add just a file
git rm --cached <filename>		<-- remote a file
git commit -m "initial commit"	<-- to commit changes (w/ comment), and save a snapshot of the local repository 
                                             * note that when you modify, you have to do a "git add ." first..else it will say no changes added to commit
git log							<-- show summary of commits
vi README.md        <-- markdown format readme file, header should start with #

git diff
git add .				
git diff --cached				<-- get the differences in the staging area, because you've already executed the "add"..

## shortcuts
git commit -a -m "short commit"		<-- combination of add and commit
git log --oneline					<-- shorter summary
git status -s						<-- shorter show changes

Exclude file
https://coderwall.com/p/n1d-na/excluding-files-from-git-locally

Integration with Github.com

Github.com setup
go to github.com and create a new repository
on your PC go to C:\Users\Karl
open git bash and type in ssh-keygen below
ssh-keygen.exe -t rsa -C "karlarao@gmail.com"		<-- this will create RSA on C:\Users\Karl directory
copy the contents of id_rsa.pub under C:\Users\karl\.ssh directory
go to github.com -> Account Settings -> SSH Keys -> Add SSH Key
ssh -T git@github.com								<-- to test the authentication
Github.com integrate and push
go to repositories folder -> on SSH tab -> copy the key
git remote add origin <repo ssh key from website>
git remote add origin git@github.com:karlarao/awrscripts.git
git push origin master
Github.com integrate with GUI
download the GUI here http://windows.github.com/
login and configure, at the end just hit skip
go to tools -> options -> change the default storage directory to the local git directory C:\Dropbox\CodeNinja\GitHub
click Scan For Repositories -> click Add -> click Update
click Publish -> click Sync
for existing repos, you can do a clone
git clone git@github.com:<name>/<repo>

github pages

sync the repo to github pages
cd ~ubuntu/telegram/
git config --global user.name "karlarao"
git config --global user.email "karlarao@gmail.com"
git add .
git status # to see what changes are going to be commited
git commit -m "."
git remote add origin git@github.com:karlarao/telegram.git
git push origin master
# git branch gh-pages # this is one time
git checkout gh-pages # go to the gh-pages branch
git rebase master # bring gh-pages up to date with master
git push origin gh-pages # commit the changes
git checkout master # return to the master branch
access the page at http://karlarao.github.io/<repo>/

render HTML file in github without git pages

http://stackoverflow.com/questions/8446218/how-to-see-an-html-page-on-github-as-a-normal-rendered-html-page-to-see-preview


track a zipfile based script repo, useful for blogs or sites

add this on your crontab 
# refresh git with the <script> scripts
0 4 * * * /home/karl/bin/git_<script>.sh

$ cat /home/karl/bin/git_<script>.sh
cd ~/github/<script directory>
rm <script>.zip
wget http://<site>.com/files/<script>.zip
unzip -o <script>.zip -d ~/github/<script directory>
git config --global user.name "karlarao"
git config --global user.email "karlarao@gmail.com"
git add .
git commit -m "."
#git remote add origin git@github.com:karlarao/<script>.git
git push origin master

then make sure to favorite the repo to get emails!


Branch, Merge, Clone, Fork

Branching	<-- allows you to create a separate working copy of your code 
Merging		<-- merge branches together
Cloning		<-- other developers can get a copy of your code from a remote repo
Forking		<-- make use of someone's code as starting point of a new project


-- 1st developer created a branch r2_index
git branch								<-- show branches
git branch r2_index						<-- create a branch name "r2_index"
git checkout r2_index					<-- to switch to the "r2_index" branch
git checkout <the branch you want to go>	* make sure to close all files before switching to another branch

-- 2nd developer on another machine created r2_misc
git clone <ssh link>					<-- to clone a project
git branch r2_misc
git checkout r2_misc
git push origin <branch name>	<-- to update the remote repo

-- bug fix on master
git checkout master
git push origin master

-- merge to combine the changes from 1st developer to the master project
	* conflict may happen due to changes at the same spot for both branches
git branch r2_index
git merge master

	* conflict looks like the following:
		<<<<<<< HEAD
		1)
		=======
		TOC:
		1) one
		2) two
		3) three>>>>>>> master
git push origin r2_index

-- pull, synchronizes the local repo with the remote repo
	* remember, PUSH to send up GitHub, PULL to sync with GitHub
git pull origin master

Some notes on forking:
  • Let's say you get assigned as a collaborator on a private repo called REPO1
  • If REPO1 gets forked as a private REPO2 by another guy, instantly you'll also be part of that REPO2
  • When the original creator delete you as a collaborator on REPO1 you will no longer see anything from that but you will still get access to REPO2

HOWTO rename a repo

what happens when I rename a git repo? do you have any advice on properly renaming a git repo?
I have pretty good news for you — since 2013, GitHub automatically redirects people from the old repo to the new repo. (There are some caveats, so read on.) Please read the Stack Overflow answer that starts with "since May 2013" on this page:

http://stackoverflow.com/questions/5751585/how-do-i-rename-a-repository-on-github

Here is the GitHub announcement of the redirect feature:

https://github.com/blog/1508-repository-redirects-are-here

https://help.github.com/articles/renaming-a-repository/

Note, it is still recommended that you update your local repository to specifically point at the new repository. You can do that with a simple:

git remote set-url origin https://github.com/YourGitHubUserName/NewRepositoryName.git

(where you replace YourGitHubUserName and NewRepositoryName with the appropriate information)

Ideally, your collaborators will also update their local repositories, but it's not an immediate requirement unless you are going to re-use the old repository name (which will break redirects and I don't recommend doing that).
