Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Depends on the version of ps as -C is not always for matching command names or even a valid option.

Comment by drizzt 272 weeks and 4 days ago

or per pid:

ps -ylC httpd | awk '{print $8}' | sed '1d'

Comment by unixx 272 weeks and 4 days ago

Estrange:

# ps -o rss -C httpd | tail -n +2 | (sed 's/^/x+=/'; echo x) | bc

1719572

So... 1719572 KB ~= 1679.26 MB?

# ./ps_mem.py | grep http

Private + Shared = RAM used Program

350.1 MiB + 7.2 MiB = 357.3 MiB httpd (201)

What's correct number? :/

Comment by tiagocruz 272 weeks and 4 days ago

This worked best for me. But I don't have bc installed.

ps -ylC httpd | awk '{print $8}' | sed '1d' | awk '{ total += $1 }END{ print total }'
