I've been following the instructions for testing AWS CodeBuild locally which has been fine until I run the codebuild_build.sh script in PowerShell. This is an example of what the command looks like:
.\codebuild_build.sh -i dockerimage -a artefactDirectory
A Command Prompt window gets opened to run the script, but is closed immediately afterwards, so I don't have enough time to see the generated output.
Is there anything I can do to either keep this window open longer, or ideally output to the PowerShell window?
I've tried piping to file, but this results in an empty file, which I suspect is because the output is put into the cmd window. And I can't spot anything in the script which would cause it to prefer a cmd window over PowerShell.
Here's the codebuild_build.sh AWS script:
#!/bin/bash
function allOSRealPath() {
if isOSWindows
then
path=""
case $1 in
.* ) path="$PWD/${1#./}" ;;
/* ) path="$1" ;;
* ) path="/$1" ;;
esac
echo "/$path" | sed -e 's/\\/\//g' -e 's/://' -e 's/./\U&/3'
else
case $1 in
/* ) echo "$1"; exit;;
* ) echo "$PWD/${1#./}"; exit;;
esac
fi
}
function isOSWindows() {
if [ $OSTYPE == "msys" ]
then
return 0
else
return 1
fi
}
function usage {
