unclear what you are trying to accomplish here. If, for example, you are trying to pgrep for all processes that have 'bash' in the process name:
#!/bin/bash
aa='bash'
xx="pgrep -f ${aa} | wc -l"
echo $xx <<< shows the command in $xx
eval ${xx} <<< runs the command in $xx

trying to get the following to output
pgrep -f 'bash' | wc -l
the var $xx has the cmd...
something's missing to allow the backtics to run the cmd..
if the cmd is hadcoded.run, it works..
can't see what the homer simpson "doh" moment is!
thanks
#!/bin/bash
#
# ptest.sh

# use predefined variables to access passed arguments

# $1
aa=$1
aa='bash'
echo $aa " pp"
xx="pgrep -f '"${aa}"' | wc -l"
echo $xx <<< this dsplays the test pgrep
echo `$xx` << err msg
echo `${xx}` << err msg...
## trying to get -- pgrep -f 'bash' | wc -l <<
## i'm getting a Usage: pgrep [....] err msg..
