Ha!
Yes, it works. Thank you!
Feel free to elaborate on ${reply%%$'\r'}.
What does it do? Remove the last char of the
string if it matches the char given? I take it
the $ is because of the special char single
quotes. I get the same result with only one %
by the way.
Does this look good?
url-exists () {
local url=$1
curl -s -I $url | head -n 1 | cut -d\ -f2,3,4
}
urls-exist () {
local -a urls
urls=($@)
local pad_max=$(echo "404 Not Found" | wc -m)
local reply
for u in $urls; do
reply=$(url-exists $u)
echo ${(r:$pad_max:: :)reply%%$'\r'} $u
done
}
alias url=urls-exist
