semver-compare-cli

CLI wrapper of the semver-compare library

Compare two semver version strings on the command line. The exit code is 0 (equal), 1 (greater), or 2 (smaller). In addition, a predicate can be added that's applied when comparing the two version.

The project is a wrapper around the semver-compare library.

Usage

Direct comparison

For a direct comparison of two versions the following exit codes are possible:

• 0 versions are equal
• 1 the first version is larger than the second version
• 2 the first version is smaller than the second version

Example, exit code is 2 because the first version is smaller than the second version:

semver-compare 1.0.0 1.0.1

Comparison with predicate

For a comparison with a predicate the following exit codes are possible:

• 0 predicate applies to the comparison of the two version
• 1 predicate doesn't apply

The following predicates are supported that shall be placed between the two version numbers:

• eq: equal
• ge: greater than or equal
• gt: greater than
• le: lower than or equal
• lt: lower than

Example, exit code is 1 because the first version is smaller than the second version:

semver-compare 1.0.0 ge 1.0.1
