test wordcount

Hello

I want to run this test:

If wordcount of a command is 0 then echo XXXX else echo YYYYY

if [ `cat /tmp/foobar.txt | awk '{print $2}' | grep database | grep -v `df -k |grep /dev/dsk | awk '{print $6}'` | wc -l` != 0 ]; then echo "all devices are created on RAID10"; else echo "Some devices are created on non-RAID10"; fi

I receive this message
-bash: command substitution: line 1: syntax error near unexpected token `|'
-bash: command substitution: line 1: ` | wc -l'
Usage: grep -hblcnsviw pattern file . . .
awk: can't open !=
-bash: [: missing `]'
Some devices are created on non-RAID10

Can you please advise?

bash$ cat /tmp/foobar.txt | awk '{print $2}' | grep database | grep -v `df -k |grep /dev/dsk | awk '{print $6}'` | wc -l

grep

GREP(1) 						      General Commands Manual							   GREP(1)

NAME

       grep - search a file for lines containing a given pattern

SYNOPSIS

       grep [-elnsv] pattern [file] ...

OPTIONS

       -e     -e pattern is the same as pattern

       -c     Print a count of lines matched

       -i     Ignore case

       -l     Print file names, no lines

       -n     Print line numbers

       -s     Status only, no printed output

       -v     Select lines that do not match

EXAMPLES

       grep mouse file	   # Find lines in file containing mouse

       grep [0-9] file	   # Print lines containing a digit

DESCRIPTION

       Grep  searches  one  or	more  files (by default, stdin) and selects out all the lines that match the pattern.  All the regular expressions
       accepted by ed and mined are allowed.  In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or  1
       occurrences,  and  |  can  be used between two regular expressions to mean either one of them.  Parentheses can be used for grouping.  If a
       match is found, exit status 0 is returned.  If no match is found, exit status 1 is returned.  If an error is detected,  exit  status  2	is
       returned.
