How do I count the number of lines output in a bash command?

You can count the lines of output in bash using the following command: <command> | wc -l
Replace <command> with the command whose output you want to count the lines of. The | symbol is a pipe, which sends the output of the command to the wc command. The -l option tells wc to count the number of lines in the input. The result will be the number of lines of output from the original command.
