I'm currently working on a script that uses curl's to check internet connectivity with and without a proxy being specified.
Basically what I'd like to achieve is having the script output fail or success according to the "method" used (direct or via proxy).
A very ugly way of doing it:
The script expects 2x arguments. The first one is the URL and the second one is the proxy address.
Whats a more dynamic way of writing that ugly if statement?
I'm receiving an exit code 64 in our batch scheduler (BMC product control-m) executing a PERL script on UX-HP. Can you tell me where I can find a list of exit codes and their meaning. I'm assuming the exit code is from the Unix operating system not PERL. (3 Replies)
#!/bin/ksh
application task run command //returns 0 if successful
if ; then echo "Ran Fine"
else echo "Didnt run"
fi
When I run the script, here is the output
Status code = 0
ksh: [0: not found.
Job didnt run
any suggestions? (4 Replies)

Hello all,
I need to print all the lines before a specific string and print a custom message 2 lines after that.
So far I have managed to print everything up the string, inclusively, but I can't figure out how to print the 2 lines after that and the custom message.
My code thus far is:... (4 Replies)
Hey, all!
Why is the "human readable" flag changing the behavior of du? And while I'm at it, can you make du only look at files, not directories. I often find myself wanting to find the largest file(s) in a dir or vol. Using 'find' itself, it seems you have to at least be able to guess the size of... (2 Replies)

curlopt_connect_to
CURLOPT_CONNECT_TO(3) curl_easy_setopt options CURLOPT_CONNECT_TO(3)NAME
CURLOPT_CONNECT_TO - Connect to a specific host and port instead of the URL's host and port
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CONNECT_TO,
struct curl_slist *connect_to);
DESCRIPTION
Pass a pointer to a linked list of strings with "connect to" information to use for establishing network connections with this handle. The
linked list should be a fully valid list of struct curl_slist structs properly filled in. Use curl_slist_append(3) to create the list and
curl_slist_free_all(3) to clean up an entire list.
Each single string should be written using the format HOST:PORT:CONNECT-TO-HOST:CONNECT-TO-PORT where HOST is the host of the request, PORT
is the port of the request, CONNECT-TO-HOST is the host name to connect to, and CONNECT-TO-PORT is the port to connect to.
The first string that matches the request's host and port is used.
Dotted numerical IP addresses are supported for HOST and CONNECT-TO-HOST. A numerical IPv6 address must be written within [brackets].
Any of the four values may be empty. When the HOST or PORT is empty, the host or port will always match (the request's host or port is
ignored). When CONNECT-TO-HOST or CONNECT-TO-PORT is empty, the "connect to" feature will be disabled for the host or port, and the
request's host or port will be used to establish the network connection.
This option is suitable to direct the request at a specific server, e.g. at a specific cluster node in a cluster of servers.
The "connect to" host and port are only used to establish the network connection. They do NOT affect the host and port that are used for
TLS/SSL (e.g. SNI, certificate verification) or for the application protocols.
In contrast to CURLOPT_RESOLVE(3), the option CURLOPT_CONNECT_TO(3) does not pre-populate the DNS cache and therefore it does not affect
future transfers of other easy handles that have been added to the same multi handle.
The "connect to" host and port are ignored if they are equal to the host and the port in the request URL, because connecting to the host
and the port in the request URL is the default behavior.
If an HTTP proxy is used for a request having a special "connect to" host or port, and the "connect to" host or port differs from the
requests's host and port, the HTTP proxy is automatically switched to tunnel mode for this specific request. This is necessary because it
is not possible to connect to a specific host or port in normal (non-tunnel) mode.
When this option is passed to curl_easy_setopt(3), libcurl will not copy the entire list so you must keep it around until you no longer use
this handle for a transfer before you call curl_slist_free_all(3) on the list.
DEFAULT
NULL
PROTOCOLS
All
EXAMPLE
CURL *curl;
struct curl_slist *connect_to = NULL;
connect_to = curl_slist_append(NULL, "example.com::server1.example.com:");
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_CONNECT_TO, connect_to);
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
curl_easy_perform(curl);
/* always cleanup */
curl_easy_cleanup(curl);
}
curl_slist_free_all(connect_to);
AVAILABILITY
Added in 7.49.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
