read without any parameters will only continue if you press enter  The DOS pause command will continue if you press any key  Use read    n1 if you want this behaviour

If you just need to pause a loop or script  and you re happy to press Enter instead of any key  then read on its own will do the job   do stuff read do more stuff   It s not end-user friendly  but may be enough in cases where you re writing a quick script for yourself  and you need to pause it to do something manually in the background

Yes to using read - and there are a couple of tweaks that make it most useful in both cron and in the terminal    Example   time rsync  options  read -n 120 -p  Press  Enter  to continue       echo       The -n 120 makes the read statement time out after 2 minutes so it does not block in cron     In terminal it gives 2 minutes to see how long the rsync command took to execute   Then the subsequent echo is so the subsequent bash prompt will appear on the next line   Otherwise it will show on the same line directly after  continue     when Enter is pressed in terminal

read -n1 is not portable  A portable way to do the same might be       trap  stty   stty -g stty -icanon   EXIT     LC ALL C dd bs 1 count 1  gt  dev null 2 gt  amp 1      lt  dev tty   Besides using  read  for just a press ENTER to continue prompt you could do   sed -n q  lt  dev tty

read does this   user host    read -n1 -r -p  Press any key to continue     key       user host       The -n1 specifies that it only waits for a single character  The -r puts it into raw mode  which is necessary because otherwise  if you press something like backslash  it doesn t register until you hit the next key   The -p specifies the prompt  which must be quoted if it contains spaces   The key argument is only necessary if you want to know which key they pressed  in which case you can access it through  key   If you are using Bash  you can also specify a timeout with -t  which causes read to return a failure when a key isn t pressed  So for example   read -t5 -n1 -r -p  Press any key in the next five seconds     key if        -eq  0     then     echo  A key was pressed   else     echo  No key was pressed   fi
