Top Forums Shell Programming and Scripting Grep a log file for the last 5 minutes of contents every 5 minutes Post 303030372 by RudiC on Friday 8th of February 2019 11:17:58 AM

The check= indicates something went wrong with your awk command as it delivered nothing on its stdout to be assigned to the variable. So

- why the "double quotes in double quotes" for the date command?
- why the extra precision in the date format?
- why the comma field separator?
- why the complicated matching?How about
Code:
check=$(awk -v d="$(date --date='-5 minutes' +'%Y-%m-%d %H:%M:%S')" '/HTTP\/1.0" 500 2042$/ {if ( d < $2 " " $3) error++} END {print error}' /tmp/test.log)

Name
       dp - parse dates RFC 822-style

Syntax
       /usr/lib/mh/dp [ -form file ] [ -format string ] [ -help ] [ -width columns ] dates

Description
       The command parses dates according to the ARPA Internet standard.  It also understands many non-standard formats, such as those produced by
       TOPS-20 sites and some UNIX sites using It is useful for seeing how MH will interpret a date.

       The program treats each argument as a single date, and prints the date out in the official RFC 822 format.  Hence, it is  usually  best	to
       enclose each argument in double quotes (") for the shell.

Options
       -form file
		 Overrides the default output format of The output is formatted according to the instructions in the specified file.  This must be
		 a format file; see

       -format string
		 Overrides the default output format of The output is formatted according to the instructions in the specified string.	This  must
		 be a format string; see

		 The  argument to the -format option must be interpreted as a single token by the shell that invokes Therefore, you should usually
		 place the argument to this option inside double quotes (").

       -help	 Prints a list of the valid options to this command.

       -width columns
		 Specifies the width of the screen in columns.

       The defaults for this command are as follows:

	      -width defaults to the width of the terminal

Examples
       This is the default format string used by
       %<(nodate{text})error: %{text}%|%(pretty{text})%>

       When an error is detected, this prints error: and the date that is in error.  Otherwise, it outputs the proper RFC 822 format of the date.
