The only ready-made way I know of to display a process's command line arguments from a shell under Solaris is the program 'pargs'. Neither version of 'ps' shipped with Solaris reports to you that it has truncated its output when it does so. The manpages say that 'ps' displays the process command line, but it does not always do this. So the doco is wrong. Worse, when ps truncates its output, yielding potentially plausible but certainly false command lines, it doesn't tell you that it's lying to you! Silent failures are the worst kind. I haven't observed the same failure under Linux using the procps tools. /usr/ucb/ps also truncates the command lines it displays, though its limit is longer than that of /usr/bin/ps.
