One -w switches from 80 column width to 132 column width,
Okay, I was able to duplicate your problem. It is due to the output of 'ps'
being truncated to 80 columns, the default terminal size. You are likely
running a wide terminal display on your interactive session (as I do)
yep, TeraTerm on Windows, very wide display.
but cron will see the default
Oh, besides (or instead of) using the -w flag, you might also consider just
shorting the width of the output lines. Since you don't need all the
information between the user and command fields, you could just use:
if ( ps -ax -o user,command | grep -iq "^root.*master" ) ; then

Well, it was just a guess. :) I tested against my 'named' daemon, using the
code you supplied and it works fine.
same code works fine for my AV daemon, but not for the MTA daemon

Trying to write a little watch-dog/keep-alive script for a couple of
related daemons, an MTA and an SMTP AV scanner.
This snippet works fine...
if ( ps aux | grep -i "^root.*master" ) > /dev/null

... when run from the command line, the echo text
