Conoscere chi usa la memoria con lo script ps_mem.py

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.
