Well, I saw a lot of advice on this but no real solution - just some debugging help.
At least from my own experience with Bash Scripting, I find that you can never use enough braces when referencing variables. So, the script should read: url="http://mypage" curl_opts="-x" curl ${url} -d \"mydata\" ${curl_opts} I would probably even go one further and use quotes in the final line as well, thus producing: curl "${url}"-d \"mydata\" "${curl_opts}" Please note that the single and double quotes have meanings as far as expansion. Also, the guys on IRC (#bash) are quite helpful - a great resource in addition to 'man bash'. $0.02 Ben ----- Original Message ---- > From: Xi Shen <davidshe...@googlemail.com> > To: gentoo-user <gentoo-user@lists.gentoo.org> > Sent: Mon, May 9, 2011 1:44:58 AM > Subject: [gentoo-user] [OT] bash script error > > It is not specific to Gentoo.
