read is a command found on Unix and Unix-like operating systems such as Linux. It reads a line of input from standard input or a file passed as an argument to its -u flag, and assigns it to a variable. It is built into shells such as Bash.[1]
Usage[edit]
The read command is used to take input from the user in shell scripts. It has a built in $REPLY variable for storing replies, but can save to other variables.[2]
Configuration[edit]
The command supports several options via flags. It can be configured to issue a message using -p instead of needing to use the echo command. It can also superficially hide text using the -s flag, limit the amount of characters with -n, store the result in an array with -a, and timeout after a certain amount of time with -t.[2]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
