Bash While Read. Retrieve the message with the echo command: Write the command and press enter:
Bash While loop explained Candid.Technology
For a mixed awk/bash solution. Retrieve the message with the echo command: Negates it, so that the condition for the while loop then always fails. The_list=$ (.code.) while read line do echo $line done < $the_list. I've been banging my head against for wall for a while with this one. Type a sentence and press enter. The terminal returns to its normal state. Then echo number is equal to zero else echo number is not equal to 0 fi done. My assumption is when the while runs line variable is empty and it should be false and while loop exit but it does not. As example lets print all users from the /etc/passwd file:
Echo $reply the $reply variable stores the read command message. Echo $reply the $reply variable stores the read command message. Web it reads once; My assumption is when the while runs line variable is empty and it should be false and while loop exit but it does not. While [ $finished != true ]; The most direct fix is to explicitly compare $finished to the string true. Using the code above gives me error: I want to ssh into a set of machines and check whether they are available (accepting connections and not being used). I just started learning shell and confused on how a read line (variable) command reads the file in. I've been banging my head against for wall for a while with this one. Read the prompt waits for the user input.
