Shell Programming and Scripting

I am trying write a script that takes user input date in the format "Mar 18". If it is march1 it is like "Mar 1" . Once i take this input i will go back to my log files and search for any failed transactions recorded that day. If there are then i will send it to a file and mail it.

I am struggling with date part, rest of the script is ready. I tried this for current date, but enhancement is to take user input.

Thanks,
Gundu

why are you focalizing on date format?

you may ask to the user to enter the date like this 20050301 as argument of the command ex:

your_script 20050301

after you can manage the date argument to transform it to match the expression you're grepping in the log files

OK I can input like 2005-03-18, i need help comparing this string with date in log file. How can i do that.

Gundu

try with strptime() function

I don't find samples to know how to use it...

I guess you should be able to do something like this:

Code:

my_var=strptime("my_string","date format",tm)

I didn't understood what "tm" stands for :-/

What does the date look like in the logfile?

my log file has date format : 2005-03-18

if it is ok to input the date in that format then this should work for sh, ksh or bash
I have written assuming ksh

Code:

#!/bin/ksh
LOGFILE="/log/files/error"   # update this to the path of your logfile
EMAIL="someone@somewhere.com"  # update this to your email address


grep ${1} $LOGFILE | uuencode transactions.txt | mailx -s "Matched Transactions for date ${1}" ${EMAIL}

Without knowing what a failed transaction looks like I can't suggest how you would filter out any other information.
