[Linux] application of reverse quotation marks (') in shellThe quotation mark (') is located at the top of the Tab key of the keyboard and the left side of the key 1. Note the difference between it and the single quotation mark (') on the left side of the Enter key. The reverse quotation mark (') is used to replace commands in Linux. Command replacement means that shell can insert the standard output of a command to any location in a command line. For example: Cl @ cl-
