as we know, invoking grep after ps with first letter of the PROCESS enclosed in brackets [] (like this: ps -aux | grep [P]ROCESS), excludes grep PROCESS from the output. so, instead of typing those brackets manualy every time, we may use the code below:

   1  
   2  FIRST=`echo $1 | sed -e 's/^\(.\).*/\1/'`
   3  REST=`echo $1 | sed -e 's/^.\(.*\)/\1/'`
   4  ps -aux | grep "[$FIRST]$REST"

you may use it as separate shell-script -- like this:

   1  
   2  #!/bin/sh
   3  FIRST=`echo $1 | sed -e 's/^\(.\).*/\1/'`
   4  REST=`echo $1 | sed -e 's/^.\(.*\)/\1/'`
   5  ps -aux | grep -v "full/path/to/your/script" | grep "[$FIRST]$REST"

or just include it in your .bashrc or similar -- like this:

   1  
   2  function psg
   3  {
   4  FIRST=`echo $1 | sed -e 's/^\(.\).*/\1/'`
   5  REST=`echo $1 | sed -e 's/^.\(.*\)/\1/'`
   6  ps -aux | grep "[$FIRST]$REST"
   7  }
