When you do a ps -ef to see a command line, it is often truncated after about 50 characters. How do you get more complete information?
> which pargs /bin/pargs > pargs 12345
“man pargs” for more info. Shows all the command line arguments as well as environment variables etc.
> ps eww -p 12345 or > tr '\0' '\n' < /proc/12345/environ
