In bash, I have an array containing a list of links, e.g.
http://xkcd.com/archive
http://what-if.xkcd.com/
http://blag.xkcd.com/
http://store.xkcd.com/
I also have a variable named $URL. I would like to set the variable $URL to a random item in the list.
You could use RANDOM variable defined by bash:
URL=${URLLIST[ $(( RANDOM % ${#URLLIST[@]} )) ] }
where URLLIST is the an array containng your urls:
URLLIST=( \
"http://xkcd.com/archive" \
"http://what-if.xkcd.com/" \
"http://blag.xkcd.com/" \
"http://store.xkcd.com/" \
)
