+# NAME
+
+CURLOPT_PREQUOTE - commands to run before an FTP transfer
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PREQUOTE,
+                          struct curl_slist *cmds);
+~~~
+
+# DESCRIPTION
+
+Pass a pointer to a linked list of FTP commands to pass to the server after
+the transfer type is set. The linked list should be a fully valid list of
+struct curl_slist structs properly filled in as described for
+CURLOPT_QUOTE(3).
+
+Using this option multiple times makes the last set string override the
+previous ones. Set it to NULL to disable its use again.
+
+libcurl does not copy the list, it needs to be kept around until after the
+transfer has completed.
+
+While CURLOPT_QUOTE(3) and CURLOPT_POSTQUOTE(3) work for SFTP,
+this option does not.
+
+# DEFAULT
+
+NULL
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  struct curl_slist *cmdlist = NULL;
+  cmdlist = curl_slist_append(cmdlist, "SYST");
+
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin");
+
+    /* pass in the FTP commands to run */
+    curl_easy_setopt(curl, CURLOPT_PREQUOTE, cmdlist);
+
+    res = curl_easy_perform(curl);
+
+    curl_easy_cleanup(curl);
+  }
+  curl_slist_free_all(cmdlist);
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
