Help using curl command Update

mido45 has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks

I want some help in the following code:

for (my $i=1; $i<=$#array1;$i++){
`curl -G -x $array1[$i]:$array2[$i] http://www.google.com`;
}
[download]

The error

curl: no URL specified!

curl: try 'curl --help' for more information

sh: line 1: :8080: command not found

sh: line 2: http://www.google.com: No such file or directory

So how can I execute curl in the right way?

Thank You in advance

Update

Hello Monks

It worked as jwkrahn suggested

I am trying now to check the output of the curl for certain conditions

What do you think is better for graping the output of the curl $variable OR @array OR in any other way you see it wright

First: What's wrong with using backticks in a void context? Then you should probably do it like this: `for my $i ( 0 .. $#array1 ) { 0 == system 'curl', '-G', '-x', "$array1[$i]:$array2[$i]", 'http:/ +/www.google.com' or die "system 'curl' failed: $?"; }` [download]	[reply] [d/l]

As a general debugging approach, print out the lines before giving them to the shell, so you see whether your values in `@array` have the values you think they should have: `# don't use a C-style loop for my $i (0..$#array1) { my $cmd = "curl -G -x $array1[$i]:$array2[$i] http://www.google.co +m"; print "Running [$cmd]\n"; system( $cmd ) == 0 or warn "Couldn't run [$cmd]: $!/$?"; };` [download]	[reply] [d/l] [select]

Strange, I don't have a proxy available but the string is formatted correctly: perl -e @array1 = qw\|localhost\|; @array2 = qw\|8080\|; print `echo curl +-G -x $array1[0]:$array2[0] http://www.google.com`; [download] === shows === curl -G -x localhost:8080 http://www.google.com Celebrate Intellectual Diversity	[reply] [d/l]

Your strings have newlines in them?	[reply]
