Full Discussion: Sleep till grep find the string

you could simply wait, till files with the name pattern occur. It could be useful to add a timeout to avoid your script to wait forever...

Code:
#! /usr/bin/bash
 cd /IN/service_packages/SMS/cdr/received
 MYDATE=`date +"%Y%m%d%H%M"`

while ! { find . -mindepth 1 -maxdepth 1 -name "cubic-live-slc-a_ACS_${MYDATE}*" | grep . ; } ; do sleep 10 ; done
  
 #get the value then divide by 60
#DAPS_SLC01
data=`grep "CALL TYPE=D" cubic-live-slc-a_ACS_$MYDATE* | wc -l`
echo Data:
r=`echo "scale=3; $data/60" | bc | sed -e 's/^\./0./;s/[0]*$//g'`
echo DAPS_SLC-a $r
 #DAPS_SLC02
data1=`grep "CALL TYPE=D" cubic-live-slc-b_ACS_$MYDATE* | wc -l`
r=`echo "scale=3; $data1/60" | bc | sed -e 's/^\./0./;s/[0]*$//g'`
echo DAPS_SLC-b $r
 #DAPS Total
r=`echo "scale=3; ($data + $data1)/60" | bc | sed -e 's/^\./0./;s/[0]*$//g'`
echo DAPS_Total $r

zegrep

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.
