Help to search multiple pattern in file with grep/sed/awk
Hello All,

I have a file which is having below type of data,

Code:
Jul 19 2011        |    123456
Jul  19 2011       |    123456
Jul 20 2011        |    123456
Jul  20 2011       |    123456

Here I wanted to grep for date pattern as below, so that it should only grep "Jul 20" OR "Jul 20" pattern only,

Code:
Jul 20 ---> Single space in between Month & Date
Jul  20 ---> Double space between Month & Date

Also I want to pass the Mon & DD through variables.

Plese advise how o do this.

xzgrep

XZGREP(1)							     XZ Utils								 XZGREP(1)

NAME

       xzgrep - search compressed files for a regular expression

SYNOPSIS

       xzgrep [grep_options] [-e] pattern file...
       xzegrep ...
       xzfgrep ...
       lzgrep ...
       lzegrep ...
       lzfgrep ...

DESCRIPTION

       xzgrep  invokes	grep(1)  on  files which may be either uncompressed or compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1).  All
       options specified are passed directly to grep(1).

       If no file is specified, then standard input is decompressed if necessary and fed to grep(1).  When reading from standard  input,  gzip(1),
       bzip2(1), and lzop(1) compressed files are not supported.

       If  xzgrep  is  invoked as xzegrep or xzfgrep then egrep(1) or fgrep(1) is used instead of grep(1).  The same applies to names lzgrep, lze-
       grep, and lzfgrep, which are provided for backward compatibility with LZMA Utils.

ENVIRONMENT

       GREP   If the GREP environment variable is set, xzgrep uses it instead of grep(1), egrep(1), or fgrep(1).

SEE ALSO

       grep(1), xz(1), gzip(1), bzip2(1), lzop(1), zgrep(1)
