Questo script in pyton, ps_mem.py, può risultare molto utile ogni qual volta si ha bisogno di sapere quanta memoria ogni singolo programma occupa. Per chi volesse provarlo:
$ wget https://www.pixelbeat.org/scripts/ps_mem.py
# mv ps_mem.py /usr/local/sbin/
# chmod 755 /usr/local/sbin/ps_mem.py
lo lanciamo con:
# ps_mem.py
il risultato è una lista minuziosa.
