+\section{An Introduction to the CLI}
+
+\subsection{Conventions}
+
+The command-line API will be referred to as the API.
+
+\subsection{Preliminaries}
+
+Logging into Ledger-SMB (1.2+) updates a row in the users\_conf table
+containing your account configuration defaults and other information.
+The implication for API users of LSMB is that you must login as part
+of running API scripts. For security purposes, it is recommended that
+scripts prompt for a password rather than storing it.
+
+All scripts included in the documentation can also be found in the doc/samples
+directory.
+
+Consider a simple example:
+
+ cd /usr/local/ledger-smb
+./ct.pl "login=name\&path=bin\&password=xxxxx\&action=search\&db=customer"
+
+The cd command moves your terminal session's current working directory into
+the main Ledger-SMB directory. Then the Ledger-SMB perl script ct.pl is called
+with one long line as an argument. The argument is really several variable=value pairs
+separated by ampersands (\&). The value for the login variable is the username
+that Ledger-SMB is to use, and the value for the password variable is the plaintext password.
+
+To build our examples we will use a username of "clarkkent" who has a password
+of "lOis,lAn3".
+
+ cd /usr/local/ledger-smb
+./ct.pl "login=clarkkent\&path=bin\&password=lOis,lAn3\&action=search\&db=customer"
+
+If we execute these commands we will get the html for the search form for
+the customer database. This result isn't useful in itself, but it shows we
+are on the right track.
+
+
+\subsection{First Script: lsmb01-cli-example.sh}
+
+With a working example, we can start to build reproducible routines that we can grow
+to do some useful work.
+
+This is a bash script which:
+
+ 1. sets NOW to the current working directory
+ 2. prompts for and reads your Ledger-SMB login
+ 3. prompts for and reads (non-echoing) your Ledger-SMB password
+ 4. changes directory to /usr/local/ledger-smb
+ 5. constructs login and logout commands and a transaction command
+ 6. logins into ledger-smb (in a real program, output would be checked for
+ success or failure)
+ 7. executes the transaction
+ 8. logs out of ledger-smb (although this is not necessary)
+ 9. returns to the original working directory
+10. exits
+
+Running lsmb01-cli-example.sh produces:
+
+\$ lsmb01-cli-example.sh
+
+Ledger-SMB login: clarkkent
+
+Ledger-SMB password:
+
+\begin{verbatim}
+<body>
+
+<form method=post action=ct.pl>
+
+<input type=hidden name=db value=customer>
+
+<table width=100%>
+ <tr>
+ <th class=listtop>Search</th>
+.
+.
+.
+\end{verbatim}
+
+A script like this would work well for simple batch transactions, but
+bash is not a very friendly language for application programming.
+
+
+A nicer solution would be to use a language such as perl to drive the
+command line API.
+

+\subsection{Second Script: lsmb02-cli-example.pl}
+
+Our second script is written in perl and logs you in but it still uses the API
+in its simplest form, that is, it builds commands and then executes them. This
+type of script can be used for more complex solutions than the simple bash script
+above, though it is still fairly limited. If your needs require, rather than have
+the script build and then execute the commands it could be written to generate a
+shell script which is executed by hand.
+
+This script begins by prompting for your Ledger-SMB login and password. Using
+the supplied values a login command is constructed and passed into the runLScmd
+subroutine. runLScmd changes directory to /usr/local/ledger-smb/ for the length
+of the subroutine. It formats the command and executes it and returns both the
+output and error information to the caller in a scalar.
+
+The script checks to see if there was an error in the login, exiting if there was.
+
+Next, the script reads some records which are stored in the program following the
+\_\_END\_\_ token. It takes each record in turn, formats it then feeds each transaction
+through runLScmd and looks at the results for a string that signals success.
+
+Once all the transactions are processed, runLScmd is called one last time to
+logout and the script exits.
