我怎么知道我安装了哪个版本的 gjslint？

Question

This may be a dumb question, but I cannot figure it out. Doing gjslint --help does not provide the answer, and --version is not a valid flag.

Any ideas?

Answer 1

Run this command:

cat `which gjslint` | grep [0-9] --color=always

or

cat $(which gjslint) | grep [0-9] --color=always

Answer 2

This one-liner prints out only the version number, convenient eg. if you want to use it in a script:

which gjslint | xargs cat | grep "ENTRY-SCRIPT" | sed 's|.*closure-linter==\([.0-9]*\).*|\1|'
