I wrote a function to handle different cases of pause in shell scripts. You can simplify it for your needs.
Code:
pause() { # [1:timeout] [2:prompt]
local P T
[[ $1 =~ ^[0-9]+$ ]] && { T=$1; shift; }
P=${1:-Hit any key...}
echo -n "$P " >&2
if ((T))
then for ((P=$T; P>0; P--))
do read -sn 1 -p "($P) " -t 1 && break
tput cub $((${#P}+3))
done
else
read -sn 1
fi
echo >&2
return
}
Default prompt is given if none provided.
The plus is that it displays a countdown.
You can call it like
Code:
pause 10
to pause 10 seconds
if no time is given it just waits for hitting a key.

I need to put a small delay into a shell script. I'm looking for something smaller than "sleep" - a second is way too long. I want to sleep something like 10 milliseconds. I've tried "usleep" and "nanosleep", but the script doesn't recognize them.

pause
pause(2) System Calls pause(2)NAME
pause - suspend process until signal
SYNOPSIS
#include <unistd.h>
int pause(void);
DESCRIPTION
The pause() function suspends the calling process until it receives a signal. The signal must be one that is not currently set to be
ignored by the calling process.
If the signal causes termination of the calling process, pause() does not return.
If the signal is caught by the calling process and control is returned from the signal-catching function (see signal(3C)), the calling
process resumes execution from the point of suspension.
RETURN VALUES
Since pause() suspends thread execution indefinitely unless interrupted by a signal, there is no successful completion return value. If
interrupted, it returns -1 and sets errno to indicate the error.
ERRORS
The pause() function will fail if:
EINTR A signal is caught by the calling process and control is returned from the signal-catching function.
