It depends on what date utility you're using. If you're on a system where the desciprtion of the -d option on the date man page is something like:
or if there is no -d option, you need to use one of the methods on the web site I referred you to in an earlier message in this thread. If you're on a system where the date man page description is something like:
Then you can use:
to get the time in seconds for the given dates specifed by having $value set to the second field on the two lines you're talking about and then convert the seconds since the Epoch to days since the Epoch and subtract. You can use "+%a" to get the abbreviated weekday name corresponding to the given dates.
Neither -d nor +%s are defined by the standards, so any use of either of these is not portable between different systems.
Hi,
I need some help figuring this out, I think it can be done using awk but I don't know how.
So, I want to take two input files, subtract some columns with each other and then output to a new results file.

bb-csvinfo.cgi
BB-CSVINFO.CGI(1) General Commands Manual BB-CSVINFO.CGI(1)NAME
bb-csvinfo.cgi - CGI program to show host information from a CSV file
SYNOPSIS
bb-csvinfo.cgi
DESCRIPTION
bb-csvinfo.cgi is invoked as a CGI script via the bb-csvinfo.sh CGI wrapper. Based on the parameters it receives, it searches a comma-
separated file for the matching host, and presents the information found as a table.
bb-csvinfo.cgi is passed a QUERY_STRING environment variable with the following parameters:
key (string to search for, typically hostname)
column (columnnumber to search - default 0)
db (name of the CSV database file in $BBHOME/etc/, default hostinfo.csv)
delimiter (delimiter character for columns, default semi-colon)
CSV files are easily created from e.g. spreadsheets, by exporting them in CSV format. You should have one host per line, with the first
line containing the column headings. Despite their name, the default delimiter for CSV files is the semi-colon - if you need a different
delimiter, invoke bb-csvinfo.cgi with the "delimiter=<character>" in the query string.
Example usage
This example shows how you can use the bb-csvinfo CGI. It assumes you have a CSV-formatted file with information about the hosts stored as
$BBHOME/etc/hostinfo.csv, and the hostname is in the first column of the file.
Use with the bbgen --docurl
The --docurl option to bbgen(1) sets up all of the hostnames on your Xymon webpages to act as links to a CGI script. To invoke the
bb-csvinfo CGI script, run bbgen with the option
--docurl=/cgi-bin/bb-csvinfo.sh?db=hostinfo.csv&key=%s
