Pattern

regexJS
\b[0-9a-f]{7,40}\b   (flags: g)

JavaScript / ECMAScript code

jsJavaScript
const re = new RegExp("\\b[0-9a-f]{7,40}\\b", "g");
const input = "commit 75d2cb0";
const matches = [...input.matchAll(re)];
console.log(matches.map(m => m[0]));

Uses `String.prototype.matchAll` for global iteration (Node 12+ / all modern browsers).

How the pattern works

Hexadecimal string of 7 to 40 lowercase characters, word-bounded. Covers Git's abbreviated SHAs and full SHA-1 hashes.
