Issues with comparing 2 files timestamps
Hi,

Im trying to write a script to first check a directory and if the filename has "ACK" in it do nothing and exit but if it has "ORD" in the filename then compare it with a dummy file created 2 minutes previous and see which one is newer

Im getting a few errors which im unsure how to rectofy any help would be much appreciated

Code:
     1  #!/bin/bash 
     2  #This is a script to alert by email if we havn't received any responces from Sangers in the last 2 minutes
     3
     4  SD= /export/home/tjmoore/sangersdummy.log
     5  SL= /export/home/tjmoore/sangerslog.log
     6  SL1= /export/home/tjmoore/sangerslog1.log
     7  ORD= cat /export/home/tjmoore/sangerslog3.log
     8  SAF= /export/home/tjmoore/sangersalert.log
     9
    10  touch /export/home/tjmoore/sangersdummy.log
    11  echo "We have not received any responses from Sangers within the last 2 minutes" > /export/home/tjmoore/sangersalert.log
    12
    13  ls -t /apps/sangerstest | head -1 > /export/home/tjmoore/sangerslog.log
    14  echo "/apps/sangerstest/" > /export/home/tjmoore/sangerslog1.log
    15  paste -d '\0' $SL1 $SL > /export/home/tjmoore/sangerslog3.log
    16
    17  if grep "ORD.xml" $SL
    18  then
    19  if ls -t $SD $ORD | head -1 | grep "ORD.xml"
    20  then
    21  /usr/local/bds/mailsend.s mailx "Sangers Responses Alert" <email addres> <email address> /export/home/tjmo
ore/sangersalert.log
    22  else
    23  exit;
    24  fi

Errors im receiving are:

Code:
bash-3.00# /export/home/tjmoore/sangers_alert_test2
/export/home/tjmoore/sangerslog.log: line 1: Test: command not found
/export/home/tjmoore/sangerslog1.log: line 1: /apps/sangerstest/: is a directory

There are several issues here:
  1. You can't have spaces after the "=" in shell variable assignments on lines 2-8. The way you have written these lines, you are setting those environment variables to empty strings while you execute the commands in the files named on those lines (and the first three diagnostic messages you're seeing errors you're getting from the commands in those files. If that is what you intended to happen, then you need to debug those command files before trying to debug this one.
  2. I don't understand what you're trying to do with the "cat" on line 7, but I'm guessing that you should just remove the cat and the spaces on both sides of it.
  3. And, the final diagnostic message comes from having an if statement on lines 17 and 19, but only one fi statement (on line 24) to terminate both of them.
I'm not making any attempt to debug the rest of your script since I'm not sure what you're trying to do with the issues raised above.

Hope this helps,
Don

From the first look, remove the spaces from both side of "=" and re-run the script

Code:
     4  SD= /export/home/tjmoore/sangersdummy.log
     5  SL= /export/home/tjmoore/sangerslog.log
     6  SL1= /export/home/tjmoore/sangerslog1.log
     7  ORD= cat /export/home/tjmoore/sangerslog3.log
     8  SAF= /export/home/tjmoore/sangersalert.log

Although I can't follow your code, the error msgs look like you're executing your log files. There's certainly one fi missing in your code. Pls post the execution log (set -vx) and the contents of all files.

Date conversion help from dd/mm/yyyy to dd/Mon/yyyy i.e. 28/10/2012 to 28/Oct/2012
Hi I have a problem with Date format in my code.

1st I am trying to convert today's date to yesterday's using

YESTERDAY3=`perl -e '@y=localtime(time()-86400); printf "%04d/%02d/%02d",$y[5]+1900,$y[4]+1,$y[3];$y[3];'`

And once it is done I am trying to using the yesterday date in a grep command to compare a logfile. But, the date format in logfile is 28/Oct/2012.

Could you please help me convert 28/10/2012 to 28/Oct/2012.

Thank You!
