This assumes you have already configured the aws command line tool. If not, check out my article on Getting Started with the AWS CLI.
The aws lambda list-functions command can be used to list the Lambda Functions you have created.
aws lambda list-functions
And here is an example of how to limit the output using the --query option.
aws lambda list-functions --query 'Functions[?FunctionName==`myfunction`]'
Something like this should be returned.
{
"Functions": [
{
"TracingConfig": {
"Mode": "PassThrough"
},
"Version": "$LATEST",
"CodeSha256": "/ur2jHd199ldQbP+Y20sw3kIHhaWwnPY6CQvSwZ6Kco=",

}
]
}
The aws lambda get-function command can be used to list a specific function, including the function location.
~]$ aws lambda get-function --function-name myfunction
