tarp

For example, you might want to sum the size of files in a tar file without doing string surgery.

tarp < example.tar | jq .Size | paste -sd+ - | bc
77857283

Or you might want to view some information that tar -tv hides from you, like PAX records:

< go-1.22-1.22.2-r1.apk gunzip | tarp | jq .PAXRecords | head
