Yes, that's a "Parameter Expansion / Remove matching suffix pattern".


man bash:
Quote:
${parameter%word}
${parameter%%word}
Remove matching suffix pattern. The word is expanded to produce a pattern just as in pathname expansion. If the pattern matches a trailing portion of the
expanded value of parameter, then the result of the expansion is the expanded value of parameter with the shortest matching pattern (the ``%'' case) or the long”
est matching pattern (the ``%%'' case) deleted.
