I want my machine to automatically download some files. That doesn't have to be very efficient. So I decided to do this with a bash script.
It works so far when I encode the URL hardly. But I want to get the files retrieved in irregular order and I thought I would use simple variables. How do I get the random number into my variable?
data_link0="https://example.com/target1.html" data_link1="https://example.com/target2.html" data_link2="https://example.com/target3.html" data_link3="https://example.com/target4.html" useragent0="Mozilla/5.0 (iPhone; CPU iPhone OS 10_0_1 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) Version/10.0 Mobile/14A403 Safari/602.1" useragent1="Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_3) AppleWebKit/604.5.6 (KHTML, like Gecko) Version/11.0.3 Safari/604.5.6" useragent3="Mozilla/5.0 (Windows 7; ) Gecko/geckotrail Firefox/firefoxversion" wget --user-agent="$user_agent[$((RANDOM % 3))]" "$datei_link$((RANDOM % 3))"
unfortunately does not work.
