grep within ksh program
Hi,
is there problem with grep command when using ksh?
I had the below command:
/usr/bin/grep \""$Mon $NewDD\"" /tmp/timemanager/intlog.$$ >> /tmp/timemanager/log.$$ 2>/dev/null

when I run ksh in debug mode, this command can not grep anything even the data is in the file.

+ /usr/bin/grep "Feb 9" /tmp/timemanager/intlog.12173
+ 1>> /tmp/timemanager/log.12173 2> /dev/null


But when I just type in the above command and it runs fine.( I think I have sh as default shell program at the prompt)

Any help would be apreciated!

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.
