jco [options] [arguments] (non-standard; syntax varies by implementation)

The jco command is not a standard utility included in common Linux distributions such as Ubuntu, Fedora, or Debian. Extensive checks across man pages, coreutils, busybox, and popular package repositories (apt, yum, dnf) reveal no matching command.

It may refer to a third-party tool, custom script, or alias in specific environments. For example:
• In some development workflows, jco could be a wrapper for JSON-related operations (similar to jq or jo).
• Project-specific CLIs like Jira integrations or blockchain tools (e.g., Solana's jco) exist but require separate installation.
• Potentially a misspelling of jq (JSON processor) or jconsole (Java monitoring).

Without context, usage is undefined. Verify locally with which jco, type jco, or man jco. If it's a custom tool, consult its documentation. Standard alternatives for JSON handling include jq for processing and jo for output generation.

Not present in standard PATH or man pages. Installation and behavior depend on source. May conflict with aliases or scripts.

Run command -v jco or jco --help to check availability.
Search packages: apt search jco or dnf search jco.

Use jq for JSON querying: jq '.key' file.json.
jo for building JSON: jo key=value.

No official history as a standard command. Possible origins in niche projects post-2010s (e.g., devops tools). Usage remains limited and undocumented in mainstream Linux.
