How can I pause my loop after x loops for x seconds?
My loop reads a list of IP addresses line by line. After 50 loops it should pause x seconds till the loop continues.

So you want us to write the script for you, instead of you searching Google how to use a loop with a counter and a conditional. – Jonny Henly Mar 07 '19 at 17:29

1You can put the `&&` inside a single `((...))` statement. `(( c++ && c == 50))`. However, do you want to pause *again* after another 50 lines? You need to reset the value of `c` to 0. An explicit `if` statement is probably cleaner: `if (( c == 50)); then c=0; sleep 60; else ((c++)); fi`. – chepner Mar 07 '19 at 17:52
