<tr> <td><tt>`&hellip;`</tt></td> <td><ul><li>Triggers command substitution; equivalent to <tt>$(&hellip;)</tt>, but is somewhat more error-prone.</li></ul></td> </tr>

 

 

<tr> <td><tt>|</tt></td> <td>Pipe. Used for redirecting input to output. Specifically, it takes the output of the command on the left hand side, runs the program on the right side, and then passes the contents of the first command's output to the second, as if it were being typed from a keyboard. 'ls -l | grep Desk' is equivalent to running "grep Desk", and then manually typing what ls -l would have output. Every press of the return key would then trigger grep until ^D is pressed to pass the EOF.<!--I think that is a very intuitive way to think about it.--></td> </tr>
