Shell Programming and Scripting

I am writing a ksh script in cygwin though it could just as easily be bash and am trying to make an alert for myself where the bell rings many times like

Code:

print '\a'

or

Code:

echo '^G'

except I want it to ping me many times not just once. For some reason doing

Code:

print '\a\a\a\a\a\a\a\a\a\a'

or similar doesn't work and I don't want a scenario where I am doing a loop around something like

Code:

print '\a'
sleep 1'

as the pause is not wanted. Is there any easy way to do it?

Thanks.

Since you want 1 line bash:

Code:

 
 for (( i=0 ; i < 100 ; i++ )); do     echo '^G'; done

I already tried a loop and it didn't work. The bell rings once. In fact my loop was almost identical to yours. Googling around had me find a line like this:

Code:

cat `cygpath -W`/Media/ding.wav > /dev/dsp

But it also didn't work.

Are you on Cygwin?

The problem is indeed to have a proper pause.

Even without a pause the loop works: but not as you expect. Try:

Code:

for i in {1..150000}; do print '\a'; done

Bye

Code:

while : ; do echo "^G" ; perl -e 'use Time::HiRes "usleep"; usleep 1250000;' ; done

or

Code:

while : ; do print "\a" ; perl -e 'use Time::HiRes "usleep"; usleep 1250000;' ; done

Under cygwin both pdksh and bash support decimal sleep durations, try

Code:

sleep 0.25

or

Code:

sleep 0.5
