When I want to find out specific process information, I usually use ps aux | grep PATTERN. There are several drawbacks, but the most annoying one for me are the missing coloumn headlines. Therefore, I made this little alias and put it into my global bash.bashrc file:
alias psgrep=’ps u | head -n 1; ps aux | grep -v grep | grep’
This enables a psgrep command which can be used like grep (since that is exactly what it is).
Maybe some of you know an even better way? Cheerio!
