shell command for pausing

Hi,

Is there a shell command that will "sleep" until a key is pressed (similar to getch() in C)?

Thanks,

Toshi

You can use:
read -n1

Or slightly better:
read -sn1 -p "Press any key to continue..."

Thanks,

read works fine in bash, but what about csh and tcsh ?

I would appreciate any help,

Toshi

I don't tend to write anything in shells other than bash but you could always start bash to run it:
bash -c "read -sn1"

If you want something that will work in all shells then you'll need an additional program such as pak.c:

Code:

#include <stdio.h>



int main(void)

{

 printf("Press any key to continue...");

 while (getchar() == EOF);

 printf("\n");

 return 0;

}

gcc -o pak pak.c

Thanks a lot!

bash -c "read -sn1" is perfect.
