Automating Mercurial Workflows with Shell Scripting

The commit history is clean, but the process that made it is not. Your shell scripts hold the real story, and when they work with Mercurial, the story is faster, safer, and repeatable.

Mercurial shell scripting lets you automate every part of the workflow: cloning, branching, merging, tagging, pushing. By combining hg commands with Bash or another POSIX shell, you can build powerful, portable workflows that remove human error.

Start with the basics. Every Mercurial command can be called in a script the same way you run it in the terminal. For example:

#!/bin/bash
REPO_PATH="/path/to/repo"
cd "$REPO_PATH"|| exit
hg pull -u
hg status

This short script updates the repository and shows current changes with no manual input. Add conditionals to control behavior:

if hg status | grep -q 'M'; then
 hg commit -m "Automated commit"&& hg push
fi

Scripts can manage branches with precision:

hg update feature-branch
hg merge default
hg commit -m "Merge default into feature-branch"

You can chain these routines into CI pipelines or trigger them with hooks. Mercurial hooks allow you to run shell scripts automatically before or after events like commits or pushes. This helps enforce code quality, run tests, or deploy without relying on memory or manual steps.

Security and stability matter. Always quote variables, check exit codes, and run set -e in scripts where safe termination is better than silent failure. Keep .hgrc clean for consistent behavior across environments.

Mercurial shell scripting is not just automation. It’s infrastructure for your version control process. It reduces mistakes, speeds delivery, and keeps teams aligned without slowing them down.

You can see these techniques in action and integrate them into real workflows without setup overhead. Go to hoop.dev and run your Mercurial shell scripts live in minutes.
