Thanks Ahamad,
But this does not seem to be working for me. Please provide alternatives.
Looking to run the below in parallel on all databases, rather then one after one

Code:
for Db in `grep -v \# /etc/oratab|cut -d\: -f1|egrep -v "+ASM"`
do
export ORACLE_SID=$Db
sqlplus -s /nolog <<EOF
connect / as sysdba
startup
exit
EOF
done

lzegrep

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)
