Snippets:
Here you will find one-liners/snippets that I use in my
Linux bash console.

Generate a random 12 character password:
head -c 12 /dev/urandom | md5sum | head -c 12

Conditional checking if program is running:
pidof nginx>/dev/null && echo yes || echo no

Always reclaim or create the same screen session:
Put this line in your .bash_profile, 
replace 'Etherial' with your favorite screen name :)
[ -z "$STY" ] && screen -Rd "Etherial"

Strip empty lines and lines starting with # from file:
Don't forget to use the -i.bak to save a backup!
In this example the main file will be overwritten and 
the original file will be called sshd_config.bak
sed -i.bak '/^#/d;/^$/d' sshd_config

Show the CPU utilization:
ps -eo psr | sort | uniq -c | grep -v PSR |
awk'{print"CPU",$2,":",$1}'

Example output:
CPU 0 : 43
CPU 1 : 37
CPU 2 : 12
CPU 3 : 19

Use grep to find occurences with linenumbers
grep -in "query" *
