Hi

The while loop seems to do the job, however I am now left with two or more outputs depending upon files found. For example when tested there were two files so grep was performed for both and output two values. Can these be summed up in the code?

Code:
 CAPmS-slc01 266.6666666000
CAPmS-slc01 16.6666666000

Also this loop still takes the last files but not one minute ago. To clarify i am trying to achieve what Robin listed below:
  • Files timestamped as the previous minute to now (ie. if I'm at 12:53, I want all 12:52 files, even if they are 90 seconds old

Hi,

just found a dirty solution for this. copy the files based on date:

Code:
mydate=`date +"%H:%M"`
 for i in `ls -lrt am1slc01_* | grep $mydate | awk '{print$9}'`; do cp $i /home/nms/scripts/CDRs/slc01; done
for i in `ls -lrt am1slc02_* | grep $mydate | awk '{print$9}'`; do cp $i /home/nms/scripts/CDRs/slc02; done

then do the required grep and delete files

Now the next step is to copy the files from one minute ago

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
