rcmorano / mu
Last active December 14, 2015 07:49
'mu' is a simple script to get real memory usage (not VSZ, not RSS but PSS) of a given PID or process pattern (uses pgrep).Check these didactic URLs for a nice explanation about memory consumption [1] and cache [2]:[1] http://emilics.com/blog/article/mconsumption.html[2] http://blog.scoutapp.com/articles/2010/10/06/determining-free-memory-on-lin…

'mutop' uses my other script 'mu' to sort any process listed in "ps aux" by memory usage. The last, the most [memory consumer]. COPY PASTE TO DOWNLOAD: wget -O /tmp/mutop.tgz https://gist.github.com/rcmorano/5053427/download; sudo mv /tmp/$(tar zxvf /tmp/mutop.tgz -C /tmp |grep mutop) /usr/local/bin/; sudo chmod +x /usr/local/bin/mutop

Last active January 4, 2016 14:48
Debian 'chef-server' bootstrap script that deploys with rvm, librarian (automagical cookbook download) and chef-solo. It's supposed to be easily maintenable since it completely relays on community cookbooks :] COPY PASTE: wget -O /tmp/bootstrap.tgz https://gist.github.com/rcmorano/5056474/download; bash /tmp/$(tar zxvf /tmp/bootstrap.tgz -C /tmp…

rcmorano / awk-print-column-if
Created May 10, 2013 19:53
Print a column selectively with #awk. Think about it like selecting a complete row (or just a column) when a column in the row matches your needs.
awk -F: '$NF == "/bin/tcsh" {print $1}' /etc/passwd
awk -F: '$1 == "johndoe" {print $1}' /etc/passwd
