Array problems in CSH

Shell Programming and Scripting
1

Hi all,

I want to use some commands and I wrap them into an array, like follows:

set ALIAS_AR = ( "ls -ltr|wc -l"       \
                       "ps -ef|grep -v grep |grep tty|wc -l"     \
                       "who|wc -l"    )

Then I use a while loop to call every step:

set no = 1
while ( $no <= $#ALIAS_AR )
if ( `$ALIAS_AR[$no]` == 7 ) then
  echo "true"
else
  echo "False"
endif
@ no++
end

And the script can't be ran as there are several problems, like
ls: invalid option -- '|'

Can anyone give me a suggestion about this?
PS: the above code is just demo, I want to use the pre-stored command to retrieve the status of running time.

Thanks

I mean how I can use the commands list in an array, or even aliases I created...

I just realized that this is not a problem about array, it is problem just like follows:
set CMD = "ls -ltr|wc -l"
`$CMD` or $CMD are all wrong, can any one give me a solution if I want to use the command like this way?

The simplest way you can do this is like this

for ex:
CMD="ls -l | wc -l"

echo $CMD | /bin/sh
