実行すると”/usr/local/bin/screenfetch: line 1286: bc: command not found”とエラーが表示されました｡bcコマンドが必要なようです｡
bcは計算するコマンドのようです｡

再度実行するとエラーは解消されました｡
ターミナルにログインした時に表示するように設定しました｡シェルはbashなので.bashrcに記述します｡

if [ -f /usr/local/bin/screenfetch ]; then /usr/local/bin/screenfetch -d -pkgs -D "$(cat /etc/redhat-release)" -A "CentOS" fi |
Distributionに/etc/redhat-releaseの内容を表示するように変更しています｡
これにより不明なDistributionになってしまいロゴがペンギンになります｡
-Aでロゴを指定しています｡またPackagesもUnknownになるので非表示にしています｡
CPUが100.0°Cになっていますが検証用仮想マシンなので情報が取得できないためと思います｡
これでログインすると表示されるようになりました｡
