 ## Architecture
@ -45,33 +39,7 @@ Deploy using interactive script:
 ### Single-File Design
 The entire application logic resides in `jrunner/src/main/java/jrunner/jrunner.java`. This is a monolithic command-line tool with no abstraction layers or separate modules.

-### Dual Mode Operation (v1.1+)
-
-The tool operates in two modes:
-
-**Query Mode** (new in v1.1):
- Activates automatically when destination flags are not provided
- Outputs query results to stdout in CSV or TSV format
- Silent operation - no diagnostic output, just clean data
- Designed for piping to visidata, pspg, less, or other data tools
- Format controlled by -f flag (csv or tsv)
-
-**Migration Mode** (original functionality):
- Activates when destination flags are provided
- Reads from source, writes to destination with batched INSERTs
- Shows progress counters and timing information
-
 ### Data Flow
-
-**Query Mode:**
-1. Parse command-line arguments (-scu, -scn, -scp for source)
-2. Read SQL query from file specified by -sq flag
-3. Connect to source database via JDBC
-4. Execute source query and fetch results (fetch size: 10,000 rows)
-5. Output results to stdout in CSV or TSV format
-6. Close connection and exit
-
-**Migration Mode:**
 1. Parse command-line arguments (-scu, -scn, -scp for source; -dcu, -dcn, -dcp for destination)
 2. Read SQL query from file specified by -sq flag
 3. Connect to source and destination databases via JDBC
@ -100,36 +68,23 @@ Command-line flags:
 - `-scu` - source JDBC URL
 - `-scn` - source username
 - `-scp` - source password
- `-dcu` - destination JDBC URL (migration mode only)
- `-dcn` - destination username (migration mode only)
- `-dcp` - destination password (migration mode only)
+- `-dcu` - destination JDBC URL
+- `-dcn` - destination username
+- `-dcp` - destination password
 - `-sq` - path to source SQL query file
- `-dt` - fully qualified destination table name (migration mode only)
+- `-dt` - fully qualified destination table name
 - `-t` - trim text fields (default: true)
- `-c` - clear target table before insert (default: true, migration mode only)
- `-f` - output format: csv, tsv (query mode only, default: csv)
+- `-c` - clear target table before insert (default: true)

 ## Key Implementation Details

-### Mode Detection
-Query mode is automatically detected at runtime (line 131) by checking if all destination flags (dcu, dcn, dcp, dt) are empty. This allows seamless switching between query and migration modes without explicit mode flags.
-
-### Query Mode Output (v1.1+)
-Query mode uses dedicated output methods:
- `outputQueryResults()` - Dispatches to format-specific methods
- `outputCSV()` - RFC 4180 compliant CSV with proper quote escaping
- `outputTSV()` - Tab-separated with tabs/newlines replaced by spaces
- All output goes to stdout; no diagnostic messages in query mode
- Helper methods: `escapeCSV()` and `escapeTSV()` for proper formatting
-
-### Batch Size (Migration Mode)
-INSERT statements are batched at 250 rows (hardcoded around line 324). When the batch threshold is reached, sql is prepended with "INSERT INTO {table} VALUES" and executed.
+### Batch Size
+INSERT statements are batched at 250 rows (hardcoded at line 324). When the batch threshold is reached, sql is prepended with "INSERT INTO {table} VALUES" and executed.

 ### Error Handling
 SQLException handling prints stack trace and exits immediately with System.exit(0). There is no transaction rollback or partial failure recovery.

 ### Performance Considerations
- Result set fetch size is set to 10,000 rows (line 190)
- Progress counter prints with carriage return for real-time updates (migration mode only)
- Timestamps captured at start and end for duration tracking (migration mode only)
- Query mode has no progress output to keep stdout clean for piping
+- Result set fetch size is set to 10,000 rows (line 173)
+- Progress counter prints with carriage return for real-time updates
+- Timestamps captured at start (line 174) and end (line 368) for duration tracking

-## Quick Start
+## install java jdk. 
+find downloads page and get latest tarball.
+https://www.oracle.com/java/technologies/downloads/

-The easiest way to get started on a new system:
-
-```bash
-git clone https://gitea.hptrow.me/pt/jrunner.git
-cd jrunner
-./setup.sh
 ```
-
-The setup script will:
- Check for Java 11+ (offers to install if missing)
- Verify Gradle wrapper is present
- Run a test build to ensure everything works
- Show you next steps
-
-## Manual Installation
-
-If you prefer to install dependencies manually:
-
-### Install Java JDK
-
-**Option 1: Package manager (recommended)**
-```bash
-# Ubuntu/Debian
-sudo apt update && sudo apt install openjdk-17-jdk
-
-# Fedora/RHEL
-sudo dnf install java-17-openjdk-devel
-
-# Arch
-sudo pacman -S jdk-openjdk
-```
-
-**Option 2: Manual download**
-Download from https://www.oracle.com/java/technologies/downloads/
-
-```bash
 wget https://download.oracle.com/java/19/latest/jdk-19_linux-x64_bin.tar.gz
-tar -xvf jdk-19_linux-x64_bin.tar.gz
-sudo mv jdk-19.0.1 /opt/
+tar -xvf downloaded_file
+```
+move the extracted folder to /opt
+put the extracted location in your path variable
+```
 export JAVA_HOME=/opt/jdk-19.0.1
 export PATH=$PATH:$JAVA_HOME/bin
 ```

-Test: `java --version`
+`java --version` to test

-### Install Gradle (optional)

+unzip -d /opt/gradle gradle-8.5-bin.zip
+export PATH=$PATH:/opt/gradle/gradle-8.5/bin

 ### using the deploy script (recommended)

+First, create the deployment directory:
 ```
+sudo mkdir -p /opt/jrunner
+```
+
+Then deploy:
+```
+# Deploy to /opt/jrunner (default, creates system-wide symlink)
 ./deploy.sh
+
+# Deploy to custom location (for testing, no symlink)
+sudo mkdir -p /opt/jrunner-test
+./deploy.sh /opt/jrunner-test
 ```

-The script will prompt you to choose:
-1. **Local install** - Fast, no sudo required, installs to `./jrunner/build/install/jrunner`
-2. **Global install** - Installs to `/opt/jrunner` with symlink at `/usr/local/bin/jrunner`
-3. **Custom directory** - Prompts for path with tab-completion support
-
-The script builds, extracts to a temporary location, and only updates the target directory after the build succeeds. This ensures your existing deployment stays intact if the build fails.

 ## usage

-### Query Mode (new in v1.1)
-
-Query mode outputs results to stdout for piping to visidata, pspg, or less. It activates automatically when destination flags are omitted.
-
-**Basic query to CSV:**
-```bash
-jrunner -scu "jdbc:as400://hostname" -scn user -scp pass -sq query.sql
+After deployment to default location:
+```
+jrunner -scu jdbc:postgresql://... -scn user -scp pass ...
 ```

-**Pipe to visidata:**
-```bash
-jrunner -scu "jdbc:as400://hostname" -scn user -scp pass -sq query.sql | visidata -f csv
+After deployment to custom location:
 ```
-
-**TSV format:**
-```bash
-jrunner -scu "jdbc:as400://hostname" -scn user -scp pass -sq query.sql -f tsv
+/opt/jrunner-test/bin/jrunner -scu jdbc:postgresql://... -scn user -scp pass ...
 ```
-
-**SQL Server example:**
-```bash
-jrunner -scu "jdbc:sqlserver://hostname:1433;databaseName=mydb" -scn user -scp pass -sq query.sql
-```
-
-**PostgreSQL example:**
-```bash
-jrunner -scu "jdbc:postgresql://hostname:5432/dbname" -scn user -scp pass -sq query.sql
-```
-
-### Migration Mode
-
-Full migration mode with both source and destination:
-```bash
-jrunner -scu jdbc:postgresql://source:5432/sourcedb \
-        -scn sourceuser \
-        -scp sourcepass \
-        -dcu jdbc:postgresql://dest:5432/destdb \
-        -dcn destuser \
-        -dcp destpass \
-        -sq query.sql \
-        -dt public.target_table
-```
-
-### Command-line flags
-
-**Source connection:**
- `-scu` - source JDBC URL
- `-scn` - source username
- `-scp` - source password
- `-sq` - path to source SQL query file
-
-**Destination connection (migration mode only):**
- `-dcu` - destination JDBC URL
- `-dcn` - destination username
- `-dcp` - destination password
- `-dt` - fully qualified destination table name
-
-**Options:**
- `-t` - trim text fields (default: true)
- `-c` - clear target table before insert (default: true)
- `-f` - output format: csv, tsv (query mode only, default: csv)
