I use the number= s but I think it stems from the days when kill didn't take
the name= s=2E    It's easier for me to remember -1 and -9 than to remember= what
the mnemonics are=2E
Same here - there first time I saw the mnemonics were in = the built-in kill command in csh=2E    Which was usefule for "kil= l -cont"
 
but to this day, since = like Ron I grew on fifth/sixth/seventh edition which used numbers, the ones= that I remember and care about are screwed into my fingers=2E

I never have an issue with -1 vs -9 with kill, but = I do not have great story about how as a young engineer I wiped out the lif= e's work of visiting professor because Tektronix had the 0 and 1 keys next = to each other on one of the terminals they made=2E  It was the console= of our 11/60 and we had two RK05's and I fat fingured /dev/r=2E=2E=2E0 ins= tead of 1=2E  Bad stuff=2E
