<p>Basically I am trying to write a script to stress test my server and ensure a command is running. My script is not working as intended. Below is the script. Basically the commands the script is executing are not being run asynchronously nor are their output being written to the results file. Any suggestions?</p> <pre><code>#Script to load test the swift command on a linux box numOfTests=100 echo "Starting Swift Load Tester ($numOfTests iterations)" mkdir /srv/www/htdocs/audiotest/stress_test mkdir /srv/www/htdocs/audiotest/half_sec_test mkdir /srv/www/htdocs/audiotest/sec_test echo "This is the prompt text" > /srv/www/htdocs/audiotest/prompt.txt echo "Beginning Stress Test..." #Clear results text file echo "" > results.txt for((i=0; i < numOfTests; i++)) do (time /opt/swift/bin/swift -n Allison-8kHz -o /srv/www/htdocs/audiotest/stress_test/$i.wav -f /srv/www/htdocs/audiotest/prompt.txt &) >> results.txt 2>&1 done echo "Done" echo "Beginning 1/2 second interval test..." for((i=0; i< numOfTests; i++)) do (time /opt/swift/bin/swift -n Allison-8kHz -o /srv/www/htdocs/audiotest/half_sec_test/$i.wav -f /srv/www/htdocs/audiotest/prompt.txt &) >> results.txt 2>&1 sleep .5 done echo "Done" echo "Beginning 1 second interval test..." for((i=0; i< numOfTests; i++)) do (time /opt/swift/bin/swift -n Allison-8kHz -o /srv/www/htdocs/audiotest/sec_test/$i.wav -f /srv/www/htdocs/audiotest/prompt.txt &) >> results.txt 2>&1 sleep 1 done echo "Done" echo "Load Testing Completed" </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
