GO lang update packages

 go list -u -m all

go list -u -m -json all (*returns json format)

 it lists all the dependencies of your Go project along with available updates. However, it does not update any packages itself; it simply informs you about potential updates.

for example:

github.com/pkg/errors v0.9.1 [v0.9.2] 

golang.org/x/sys v0.0.0-20220315054443-0e35b0f21f97 [v0.0.0-20220315190503-a33c662eeddc]

sh

Copy code

go get -u <package-path>

Replace <package-path> with the path of the package. For example, to update github.com/pkg/errors, run:

sh

Copy code

go get -u github.com/pkg/errors

2. Install a Specific Version

If you need to install a specific version, append the version number with an @ symbol:

sh

Copy code

go get <package-path>@<version>

For example, to install version v0.9.2 of github.com/pkg/errors:

sh

Copy code

go get github.com/pkg/errors@v0.9.2

go mod tidy

This command will clean up the go.mod and go.sum files, removing any unused dependencies and ensuring everything is in order.

4. Verify the Update

Check your go.mod file to ensure the dependency has been updated to the expected version.

#!/bin/bash

# List all modules with available updates

modules=$(go list -u -m -json all | jq -r 'select(.Update) | .Path + "@" + .Update.Version')

# Update each module

for module in $modules; do

    echo "Updating $module"

    go get $module

done

# Tidy up the dependencies

go mod tidy

echo "All packages updated successfully."
