KornShell logo KornShell

The KornShell language was designed and developed by David G. Korn at AT&T Bell Laboratories.

Emisar.dev logo Emisar.dev

One governed MCP server connects any AI agent to a finite action catalog, enforced on-host with pack trust, policy gates, human approvals, and a hash-chained audit trail.

Emisar is the last MCP server youโ€™ll need to install: a Zero-Trust gateway connecting Claude, Cursor, ChatGPT, and any AI agent to your infrastructure. One server handles production access, debugging, alerts, and internal operations, with new capabilities added as packs. Agents can inspect real production state, debug what they shipped, and help resolve incidents. Safe reads run automatically; policy allows, blocks, or routes risky actions for approval. No SSH keys, VPNs, remote shells, or standing shell access โ€” and every call is recorded.

KornShell features and specs

  • Compatibility
    KornShell (ksh) maintains backward compatibility with Bourne Shell (sh), making it easy for users familiar with sh to transition without altering their existing scripts substantially.
  • Advanced Scripting Features
    ksh offers advanced scripting capabilities such as associative arrays, floating-point arithmetic, and built-in regular expressions, providing more powerful and flexible scripting tools.
  • Job Control
    It provides robust job control, allowing users to manage and switch between multiple background tasks and processes easily.
  • Interactive Use
    ksh supports features like command aliasing, history manipulation, and inline editing, enhancing its utility in interactive command-line environments.
  • Performance
    ksh scripts often execute faster than those written in other shells like csh, due to more efficient resource management and execution mechanisms.

Possible disadvantages of KornShell

  • Complexity
    ksh is more complex compared to simpler shells like sh, making it potentially overwhelming for beginners or those seeking simplicity.
  • Portability
    Not all systems come with ksh pre-installed, and differences between ksh88 and ksh93 can lead to portability issues across different Unix-like systems.
  • Learning Curve
    Due to its rich feature set, ksh has a steeper learning curve, which could be a barrier for new users unfamiliar with shell scripting.
  • Limited Adoption
    Despite its capabilities, ksh is not as widely adopted as other shells like bash or zsh, meaning less community support and fewer resources available.
  • Licensing
    ksh is under the Common Public License, which may pose constraints for users or organizations compared to more permissively licensed shells.

Questions & Answers

As answered by people managing KornShell and Emisar.dev.

How would you describe the primary audience of your product?

Emisar.dev's answer:

emisar is for SRE, DevOps, platform engineering, infrastructure, and security teams that want AI agents to inspect and operate production systems. It is especially relevant to teams managing multiple Linux hosts, clusters, databases, cloud services, or regulated environments where unrestricted shell access and incomplete audit records are unacceptable.

Which are the primary technologies used for building your product?

Emisar.dev's answer:

The hosted control plane and operator interface use Elixir, Phoenix, LiveView, PostgreSQL, and Tailwind CSS. The host runner and MCP bridge are written in Go. Action packs use YAML and JSON Schema, while production infrastructure is managed with Terraform on Google Cloud. The system communicates through MCP, OAuth 2.1, TLS, and WebSockets.

Who are some of the biggest customers of your product?

Emisar.dev's answer:

  • Blitz.gg - game analytics for billions of matches and a pretty large infrastructure.

What's the story behind your product?

Emisar.dev's answer:

Founder Andrii Dryga spent a decade working as a CTO, full-stack engineer, SRE, and DevOps engineer. He experienced the cost of running the wrong command on the wrong cluster, while also seeing AI solve operational problems in seconds. emisar grew from the need to preserve both truths: AI agents are useful, and production access must remain bounded. Its answer is to give agents a reviewed catalog of operations instead of a blank terminal.

What makes your product unique?

Emisar.dev's answer:

emisar lets AI agents work on real infrastructure without giving them a shell. Agents choose from a finite catalog of typed, versioned actions. Policy decides what runs, what requires approval, and what is denied, while an outbound-only runner verifies the action again on the host. New capabilities arrive as packs behind the same MCP integration, and every request is recorded in both a searchable audit trail and a tamper-evident host journal. [

Why should a person choose your product over its competitors?

Emisar.dev's answer:

Choose emisar when you want an agent to keep investigating and handling routine operations without handing it SSH credentials or supervising every call. Compared with raw shell access, copy-paste workflows, or one-off MCP servers, emisar provides reviewed action contracts, host-level enforcement, risk-based policy, scoped access, approvals, pack integrity checks, and a durable audit trail. It is built specifically for governed infrastructure access rather than generic automation.

  • Trying to Set-up android9(ver6) in VirtualBox
    Well now I'm at the point that I see it's calling for the Korn shell, which I'm not directly familiar with, and seemed to stop on the mouse input driver. I'll change my VBox mouse device settings and see what happens from there... Source: over 4 years ago
