[Linux] コマンド検索パス一覧を表示する時はecho $PATH | tr ":" "\n"で見やすく出力

環境変数$PATHに設定してあるコマンド検索パスの一覧をechoコマンドで出力する際に、単にecho $PATHだと改行が無くて見辛かったのでtrコマンドも合わせて改行させた。

echo $PATH

$ echo $PATH
/usr/local/opt/openssl/bin:/Users/rintaronakamura/Library/Android/sdk/platform-tools:/Users/rintaronakamura/Library/Android/sdk/tools:/Users/rintaronakamura/.sdkman/candidates/gradle/current/bin:/Users/rintaronakamura/.rbenv/shims:/Users/rintaronakamura/.rbenv/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/share/dotnet:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/usr/local/bin/postgres:/Users/rintaronakamura/.nodebrew/current/bin
