Java How to stop infinite loop
Im unable to stop the below infinite loop (bash script). Can someone tell me why this isnt responding to signals eg: ctrl+c (SIGINT) or ctrl+z

Code:
 c=0
 test_loop() {
     c=$(($c+1))
     echo "count value is : $c "
     sleep 1
     test_loop
 }

Im using: SunOS 5.10

PS: If run this as a script then it is responding to kill signals, but running in command line makes it unresponsive

How is this function called in the script
This code by itself will not run in a loop.
That's just a function definition.

bmk: when I execute the code in command line it isnt responding, but when i put in the script im able to bring it down by pressing ctrl+c. So your suggestion aint working for me.

elixir_sinari: yes off-course we need to call the function.

Code:
solaris$ :>  test_loop

Is it possible for you to post what you type in and show how the function has gone "rogue".

elixir_sinari: I just type "test_loop" and hit enter
the function is a recursive one (calls itself) hence you need a if condition in the function body so that it can be terminated when a certain condition is met(e.g when $c reaches a specific value).

@codemaniac, I think the OP knows that obvious fact. He is just asking for a way to stop the loop.

@Arun_Linux, I don't seem to be having any problem stopping the loop in bash 4.1 on cygwin using SIGINT.
