checkver

POSIX shell script that checks whether the provided version fulfills the provided version requirement(s).

Installation

# Download the script and save it to /usr/local/bin
wget -O /usr/local/bin/checkver https://raw.githubusercontent.com/frenzox/checkver/main/checkver

# Make script executable
chmod +x /usr/local/bin/checkver

# Prove it works
checkver -V

You probably want to make sure the directory where you install checkver to is included in your PATH.

Usage

See examples from checkver -h:

Usage: checkver [OPTION] <version> <requirements,...>
Checks if the provided version fulfills the provided requirement(s)

Options:
  -h                 Display this help and exit
  -V                 Output version information and exit

Positional arguments:
  version            Version string to test, semver compliant
  requirement        Comma separated requirements string

Examples:
  checkver "1.0.1" "1.0.0"
  checkver "1.0.1" "^1.0.0"
  checkver "2.2.1" "~2"
  checkver "1.0.0" "=1.0.0"
  checkver "1.0.0" ">=1.0.0"
  checkver "1.5.0" ">1.0.0, <=2.0.0"

Supported operators for the requirement string:
 >, >=, <, <=, =, ~, ^

The semantics for the check follow the one from Cargo:
