+## Bash Scripts to test Watson AI Services
+
+This folder contains bash scripts that are using **curl** command to call Watson APIs as explained on Watson getting started pages.
+
+Test whether **curl** is installed. Run the following command on the command line. 
+
+```bash
+curl -V
+```
+
+If the output lists the curl version with SSL support, you are all set otherwise install it.
+
+```bash
+sudo apt install curl
+```
+To run a script, 
+* change to the folder where you have the scripts:
+```bash
+cd ~/TJBOT/bash_tests
+```
+* type **./** followed by the name of script file then space then your api-key for the related service
+
+```bash
+./tone_analyzer_4.sh pomy6gsgO4kmjtNa3eiuhg7haziujhyf0Ps8WxTrIom6
+```
+
+example output:
+
+```json
+{"utterances_tone":[
+
+    {"utterance_id":0,
+        "utterance_text":"Hello, I'm having a problem with your product.",
+        "tones":[{  "score":0.686361,

+    {"utterance_id":1,
+        "utterance_text":"OK, let me know what's going on, please.",
+        "tones":[{  "score":0.92724,

+                    "tone_name":"Polite"}]},
+
+    {"utterance_id":2,"utterance_text":"Well, nothing is working :(",
+        "tones":[{  "score":0.997795,
+                    "tone_id":"sad",
+                    "tone_name":"Sad"}]},
+
+    {"utterance_id":3,"utterance_text":"Sorry to hear that.",
+        "tones":[{  "score":0.730982,
+                    "tone_id":"polite",
+                    "tone_name":"Polite"},
+
+                 {  "score":0.672499,
+                    "tone_id":"sympathetic",
+                    "tone_name":"Sympathetic"}]}
+    ]
+}
+```
+
+Please note the following:
+
+* api-key is the only parameter that you need to pass to the script
+* script output will be either text in json format or a file that will be written to a subfolder
+* scripts are modified version from what is given by Watson getting started to make it easier to understand
+* service URLs are embedded inside the script, you might need to change it if you are using different service version
+* you can get more details/help/examples on Watson Portal.
