Git object files are a zlib compressed data file type.
We can check this by running the file command. “6ae4147121f0165e7c0e309bad649c2c4d3a55” is our git file of interest.
$ file 6ae4147121f0165e7c0e309bad649c2c4d3a55
6ae4147121f0165e7c0e309bad649c2c4d3a55: zlib compressed data
The above link has helpful information. Easiest way I found was to install zlib-flate by installing qpdf with apt.
sudo apt install qpdf
We can now use the zlib-flate command with the -uncompress option to decompress the file and print the contents.
$ zlib-flate -uncompress < 6ae4147121f0165e7c0e309bad649c2c4d3a55 var b64 = (""); console.log(b64);
