Hello guys,

Thanks very much for your replies, now I feel I am closer

I tried what you suggested, but it seems that I am losing lines when retrieving the information, let me explain:

My script is doing the following:

Code:
log_exec=`$path_ds_ex/dsjob -logdetail $proyecto $job`
#(doing this because need to use this many times later on)
 
numtimes=`echo $log_exec | grep "Waiting for job" | grep "to start" | wc -l `
echo $numtimes

Result for this is: 1


Otherwise, if I do this:

Code:
log_exec=`$path_ds_ex/dsjob -logdetail $proyecto $job`
 
numtimes=`$path_ds_ex/dsjob -logdetail $proyecto $job | grep "Waiting for job" | grep "to start" | wc -l `
echo $numtimes

Now result is correct: 24


On the other hand, I tried the code fpmurphy suggested, but got nothing at all!

Code:
echo "$log_exec" | while read a b c d e f; do
  if [[ "$a $b $c" == "Waiting for job"  && "$e $f" == "to start" ]]
    then
        echo "$d"
    fi
done

Can you please guys advice?

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.
