add option to remove verbose header and footer (need this for batch scripting) about ps_mem

[pixelb]

The closest you can get currently I think is:
ps_mem -s -p $(pgrep -d, -f php) | tail -n+3 | head -n-3

[pixelb]

ps_mem --show-cmdline -p $(pgrep -d, -f php-cgi)

excuse me, what I'm about is something like this

[root@dokonlin ~]# ps_mem --no-headers-footers --show-cmdline -p $(pgrep -d, -f php)
332.0 KiB + 936.0 KiB =   1.2 MiB	php-fpm: master process (/etc/php-fpm.conf)
660.0 KiB +   4.3 MiB =   4.9 MiB	php-fpm: pool www               (5)
 34.5 MiB +   1.9 MiB =  36.4 MiB	php-fpm: pool apache            (3)
