How to check whether a long time task running properly? (How to launch a function after given time while a command is running)?
I'm writing a bash script to download some files regularly. I'd like to informed while a successful download is started.
But I couldn't make it right.
#!/bin/bash
URL="http://testurl"
FILENAME="/tmp/test"
function is_downloading() {
sleep 11
echo -e "$DOWNLOADING" # 0 wanted here with a failed download but always get empty
if [[ $DOWNLOADING -eq 1 ]]; then
echo "Send Message"
# send_msg
fi
}
while [[ 0 ]]; do
is_downloading &
DOWNLOADING=1
curl --connect-timeout 10 --speed-time 10 --speed-limit 1 --location -o "$FILENAME" "$URL"
DOWNLOADING=0
echo -e "$DOWNLOADING"
sleep 3600
done
