how to install Bitcoin and bitcoin cash on the same ubuntu server?

I've installed bitcoin core as the documentation in bitcoin.org and its working great. then, I tried to install bitcoin-ABC manually as following:

1. wget bitcoin-cash-gnu.tar.gz
2. tar xzf bitcoin-cash-gnu.tar.gz
3. cd bitcoin-cash-gnu/bin
4. ls

bitcoin-cli bitcoin-qt bitcoin-tx bitcoind test_bitcoin

5. I have renamed bin directory files so it doesn't conflict with bitcoin-legacy.

bitcoinCash-cli bitcoinCash-qt bitcoinCash-tx bitcoinCashd test_bitcoinCash

6. then i've installed it on /etc/usr/bin

sudo install -m 0755 -o root -g root -t /usr/local/bin bitcoin-cash-gnu/bin/bin/*

Then I tried to run bitcoinCashd and

Command not found
