The command should be one line

2. A bash command to search through the past 50 commands that a user has run via bash, and search for only ones containing "cd" or "ls". All other commands should be ignored. For example, say that the user has run a variety of different kinds of commands in the past 50 commands, and only 3 contain those keywords. Those would be: $ls-lta$cd/usr/lib$grep"cdna" In that case, if we ran the command, we should get: \$your_command cd /usr/lib grep "cdna" ls -lta The commands should be sorted via the sort command
