Hi Rudi,

Yes, looping this will be good, however, in the output I am getting one extra <\/td> after every entry. O/p in the email attached: Below is the code:

Code:
#!/bin/bash

DT=(20170811 20170831)
for i in 0 1

do echo "<table border=1>"

mysql test -e "select c.CenterID,a.MIC,c.ExchangeName,a.CountryCode,a.EventDate,a.EventDayOfWeek,b.eventName from exch_calendar_event a left join exch_calendar_eventName b on a.EventID=b.ID left join exch_calendar_mic c on a.MIC=c.MIC where EventDate=DATE_FORMAT(${DT[$i]},'%Y%m%d') order by a.MIC;" |
         while read LINE
          do  echo "<tr><td>${LINE// /<\/td><td>}</td></tr>"
         done
         echo "</table><br>"
done >> mail.txt
cat header1 mail.txt footer | sendmail -t

Also, I could not understand the ${LINE// /<\/td><td>} part. Is it replacing the tab with </td><td>.

Please let me know. Once the output is sorted out, I need to optimize the script to run everyday which will fetch the data for today, t-1 and t-2 (provided all are business days).

For eg: If today is Tuesday, then the query will be executed 3 times for today, Monday, friday and send the output (if any) over email. No blank emails required.

Currently, I am just checking the output format with hardcoding the date, however, above is the overall requirement of the script.

Anyone can suggest me. Thanks in advance!!

gss_unwrap(3GSS)				  Generic Security Services API Library Functions				  gss_unwrap(3GSS)

NAME
gss_unwrap - verify a message with attached cryptographic message SYNOPSIS
cc -flag ... file ...-lgss [library ...] #include <gssapi/gssapi.h> OM_uint32 gss_unwrap(OM_uint32 *minor_status, const gss_ctx_id_t context_handle, const gss_buffer_t input_message_buffer, gss_buffer_t out- put_message_buffer, int *conf_state, gss_qop_t *qop_state); DESCRIPTION
The gss_unwrap() function converts a message previously protected by gss_wrap(3GSS) back to a usable form, verifying the embedded MIC. The conf_state parameter indicates whether the message was encrypted; the qop_state parameter indicates the strength of protection that was used to provide the confidentiality and integrity services. Since some application-level protocols may wish to use tokens emitted by gss_wrap(3GSS) to provide secure framing, the GSS-API supports the wrapping and unwrapping of zero-length messages. PARAMETERS
The parameter descriptions for gss_unwrap() follow: minor_status The status code returned by the underlying mechanism. context_handle Identifies the context on which the message arrived. input_message_buffer The message to be protected. output_message_buffer The buffer to receive the unwrapped message. Storage associated with this buffer must be freed by the application after use with a call to gss_release_buffer(3GSS). conf_state If the value of conf_state is non-zero, then confidentiality and integrity protection were used. If the value is zero, only integrity service was used. Specify NULL if this parameter is not required. qop_state Specifies the quality of protection provided. Specify NULL if this parameter is not required. ERRORS
gss_unwrap() may return the following status codes: GSS_S_COMPLETE Successful completion. GSS_S_DEFECTIVE_TOKEN The token failed consistency checks. GSS_S_BAD_SIG The MIC was incorrect. GSS_S_DUPLICATE_TOKEN The token was valid, and contained a correct MIC for the message, but it had already been processed. GSS_S_OLD_TOKEN The token was valid, and contained a correct MIC for the message, but it is too old to check for duplica- tion. GSS_S_UNSEQ_TOKEN The token was valid, and contained a correct MIC for the message, but has been verified out of sequence; a later token has already been received. GSS_S_GAP_TOKEN The token was valid, and contained a correct MIC for the message, but has been verified out of sequence; an earlier expected token has not yet been received. GSS_S_CONTEXT_EXPIRED The context has already expired. GSS_S_NO_CONTEXT The context_handle parameter did not identify a valid context. GSS_S_FAILURE The underlying mechanism detected an error for which no specific GSS status code is defined. The mecha- nism-specific status code reported by means of the minor_status parameter details the error condition. ATTRIBUTES
