as already answered:
ps ax | awk '/[/]slapd /{n++} END{print n}'
searching '[s]lapd' will avoid grep "auto-matching", but would still return
commands like "vim /etc/slapd.conf" or ./myscript-slapd
about pgrep, like the usual grep, it needs a better expression than the
process name, otherwise it would return the same results as a grep
however, a perfect match may be done looking for the exact path
('[/]usr/local/bin/slapd '), but would still fail when, for ex. running
`objdump /usr/local/bin/slapd -x'
also, if you want to count the number of outputed lines, using [p]grep and
wc makes two processes, while awk can do it all alone.
awk ftw!
