Official JtR doesn't have support for cracking RAR files in-built.

If you are using jumbo then first run rar2john tool on your RAR files
rar2john testabc.rar > rardump
Then run john on the generated rardump file.
john --format=rar rardump
Using jumbo should be faster than your shell script. However cracking
RAR files is extremely slow in general.
