yes: Repeated Text

Written by Benjamin Cane on 2011-08-11

Ever feel like you are repeating yourself? Well with yes you can type a string only once and it will repeat; over and over and over and over and over again.


[[email protected] tmp]$ yes "yes will print repeated text"   
yes will print repeated text  
yes will print repeated text  
yes will print repeated text  
yes will print repeated text  
yes will print repeated text

So why would you want a command that prints text repeatedly? Ever run into situations like this?

[[email protected] somedir]$ rm -i *.txt  
rm: remove regular empty file `100.txt'? y  
rm: remove regular empty file `10.txt'?

While rm has a -f flag that will not ask you if you want to remove the file there are other commands/scripts that do not.

[[email protected] somedir]$ ls | wc -l  
[[email protected] somedir]$ yes y | rm -i *.txt  
**Output Truncated**  
[[email protected] somedir]$ ls | wc -l
