Larger Script Organization

Script Layout

Pick a Shape

As scripts grow, project layout matters. A single-file script can stay small, while a project layout separates entry points, helpers, and tests.

Program

Play the script to choose the layout and see the planned entry point and directories.

script_layout_plan.sh 
#!/usr/bin/env bash

layout=
if [ "$layout" = "project" ]; then
    entry="bin/deploy"
    dirs="bin lib test"
else
    entry="./deploy.sh"
    dirs="."
fi
echo "$layout:$entry:$dirs"

#!/usr/bin/env bash

layout=
if [ "$layout" = "project" ]; then
    entry="bin/deploy"
    dirs="bin lib test"
else
    entry="./deploy.sh"
    dirs="."
fi
echo "$layout:$entry:$dirs"
layout Layout is the file and directory shape of the script project.
entry point The entry point is the executable script users run.
test directory A larger layout makes room for tests beside helpers and entry points.
