csantanapr commented on issue #3138: Add bash kind action
URL: https://github.com/apache/incubator-openwhisk/pull/3138#issuecomment-366863338
 
 
   Recent changes to dockerSkeleton runtime now allows for better support for bash actions.
   Using `--native` with a simple script is the recommend way for bash actions.
   
   For example:
   
   bash.sh reads  a line from \<STDIN\>
   ```
   $ cat bash.sh
   #!/bin/bash
   read ARGS
   A=`echo "$ARGS" | jq '."a"'`
   B=`echo "$ARGS" | jq '."b"'`
   C=`echo "$ARGS" | jq '."c"[0]'`
   RES=$(($B + $C))
   echo A is $A
   echo "{ \"result\": \"$RES\" }"
   ```
   ```
   wsk action update bash bash.sh --native
   ```
   ```
   ok: updated action bash
   ```
   
   ```
   wsk action invoke bash -p a A -p b 123 -p c '[1,2,3]' -r
   ```
   ```json
   {
       "result": 124
   }
   ```
   ```
   wsk activation logs --last --strip
   ```
   ```
   A is "A"
   ```
   
   docs will update to reflect this new usage.
