Subject: string overwrites string when echoed
Date: Sat, 09 Sep 2017 14:55:23 +0200 [thread overview]
Message-ID: <86o9qkqbes.fsf@zoho.com> (raw)
Here is a problem that really puzzles me.
I re-wrote the original DWIM function, that
branched on $#, into two function to identify
the issue. Now I know where the issue is - the
commented lines - but not why it
happens. Ideas?
TIA.
url-exists () {
local url=$1
curl -s -I $url | head -n 1 | cut -d\ -f2,3,4
}
alias url=url-exists
urls-exist () {
local -a urls
urls=($@)
local reply
for u in $urls; do
reply=$(url $u)
echo "$u $reply" # works
echo "$reply $u" # doesn't work, $u overwrites $reply
done
}
alias urls=urls-exist
