eDebug

eDebug is a web-based debugger built specifically for bash scripts, bringing the kind of interactive debugging experience developers expect from modern IDEs to shell scripting. Shell scripts have always been harder to debug than code in other languages. There's no built-in debugger in bash that matches what you get with Python, JavaScript, or any compiled language. Developers typically resort to echo statements scattered through their code, set -x traces that produce overwhelming output, or manual inspection of intermediate files. eDebug changes this by providing breakpoints, variable watching, and step-by-step execution through a visual interface that runs in your browser. You see exactly what your bash code is doing at each stage of execution, with full visibility into variable state.

Shell scripts often start as simple automation but grow into complex systems that handle deployments, data pipelines, backup routines, or server administration tasks. A script that began as ten lines to restart a service becomes five hundred lines managing multiple services, checking dependencies, handling errors, and logging outcomes. When something goes wrong in a script of that size, tracking down the issue can mean inserting print statements throughout the code, running the script repeatedly with different inputs, and piecing together what happened from scattered output across terminal sessions. eDebug replaces this trial-and-error approach with structured debugging. You set a breakpoint where you suspect the problem lies, run the script, and examine the state of every variable when execution pauses. Then you step forward one line at a time, watching how values change.

Installation happens through a single command piped from the eDebug website, keeping setup minimal. The cloud-based architecture means there's no local debugger daemon to install, configure, or maintain. Your scripts run with the debugger attached, and the web interface communicates with the execution environment to control flow and retrieve state. This approach works particularly well for scripts running on remote servers or in cloud environments where installing traditional debugging tools might be impractical, restricted by security policies, or simply more hassle than it's worth. You can debug scripts on production servers, in containers, or across SSH sessions without pre-installing anything beyond the initial curl command.

The variable watching capability addresses one of the most tedious aspects of bash debugging and probably saves more time than any other feature. In traditional bash debugging, you might add echo statements for every variable you care about, rerun the script, scroll through output to find the values, realize you forgot to print something important, add another echo, and repeat the cycle. With eDebug, you declare which variables to watch, and their values update in real time as you step through code. You see immediately when a variable takes an unexpected value, remains empty when it should have been populated, or gets overwritten by a later assignment. String manipulations, command substitutions, and arithmetic operations all become visible in their results.

Breakpoint functionality lets you skip past the parts of your script that work correctly and pause execution exactly where problems occur. This is especially valuable in scripts that process files, iterate over large datasets, perform network operations, or execute time-consuming commands before reaching the problematic section. Rather than waiting through the entire execution or temporarily commenting out earlier code blocks (and hoping you remember to uncomment them later), you jump directly to the relevant lines and inspect state from there. You can set multiple breakpoints to catch execution at different points, comparing state across locations to understand how values evolve.

Step-by-step execution reveals control flow that can be surprisingly opaque in bash. Conditional statements with complex test expressions, nested loops, function calls, subshell operations, and pipe chains all become visible as discrete steps you can observe individually. When a script behaves differently than expected, stepping through shows exactly which branch of an if statement was taken, how many times a loop iterated, where a function returned early, or how subshell variable scoping affected your values. This visibility transforms debugging from educated guessing into methodical inspection where you can verify assumptions against reality.

The positioning as a cloud debugger reflects how scripts are actually deployed and run in modern infrastructure. Automation runs across distributed systems, inside containers, on serverless platforms, and through CI/CD pipelines where you may not have direct terminal access. Being web-based means you can debug from any machine with a browser, without needing the same local environment where the script runs. For teams managing automation across multiple servers, cloud providers, or container orchestration systems, this accessibility removes friction from the debugging workflow. An online demo is available directly on the eDebug website for developers who want to try the interface before integrating it into their own scripts.
