Yes, that is how the script works.
The result of uname -n is being stored in HOST variable.
Then, the HOST is appended with "$ "(Dollar and a space). This is stored in PS1.

If I don't explain my issue well enough, I apologize ahead of time, extreme newbie here to scripting.

Hi all,
I'm not clear of this regexp command:
regexp {(\S+)\/+$} $String match GetString
From my observation and testing,
if $String is abc/def/gh
$GetString will be abc/def
I don't understand how the /gh in $String got eliminated.
Please help. Thanks (2 Replies)

curlopt_resolve
CURLOPT_RESOLVE(3) curl_easy_setopt options CURLOPT_RESOLVE(3)NAME
CURLOPT_RESOLVE - provide custom host name to IP address resolves
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESOLVE,
struct curl_slist *hosts);
DESCRIPTION
Pass a pointer to a linked list of strings with host name resolve information to use for requests 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 name resolve string should be written using the format HOST:PORT:ADDRESS where HOST is the name libcurl will try to resolve,
PORT is the port number of the service where libcurl wants to connect to the HOST and ADDRESS is the numerical IP address. If libcurl is
built to support IPv6, ADDRESS can of course be either IPv4 or IPv6 style addressing.
This option effectively pre-populates the DNS cache with entries for the host+port pair so redirects and everything that operations against
the HOST+PORT will instead use your provided ADDRESS. Addresses set with CURLOPT_RESOLVE(3) will not time-out from the DNS cache like ordi-
nary entries.
The provided ADDRESS set by this option will be used even if CURLOPT_IPRESOLVE(3) is set to make libcurl use another IP version.
Remove names from the DNS cache again, to stop providing these fake resolves, by including a string in the linked list that uses the format
"-HOST:PORT". The host name must be prefixed with a dash, and the host name and port number must exactly match what was already added pre-
viously.
DEFAULT
NULL
PROTOCOLS
All
EXAMPLE
CURL *curl;
struct curl_slist *host = NULL;
host = curl_slist_append(NULL, "example.com:80:127.0.0.1");
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_RESOLVE, host);
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
curl_easy_perform(curl);
/* always cleanup */
curl_easy_cleanup(curl);
}
curl_slist_free_all(host);
AVAILABILITY
Added in 7.21.3. Removal support added in 7.42.0.
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
