Eclipsed launched a process for me, and I'd like to see the full command line used.

I tried "ps auxwww", but it seems to truncate the path to 4096 characters, is there any way to get PS to stop truncating the path, or to use another tool to find the full path?

Hmm, maybe the answer is to recompile the kernel? wtf. stackoverflow.com/questions/199130/… – Alex Black Mar 1 '12 at 19:11
For my case, which is a java app, you can use jconsole to get the full classpath it looks like – Alex Black Mar 1 '12 at 19:13
Is it possible to redirect it to a file and get the entire command line? – James Mar 1 '12 at 23:21
I don't think so, it looks like /proc/{PID}/cmdline is truncated at 4096 characters, a hard limit set in the kernel – Alex Black Mar 2 '12 at 2:16

cat /proc/{PID}/cmdline

Where {PID} is the process ID of the process in question.

/proc/*/cmdline doesn't contain a trailing newline, so echo $(< /proc/7851/cmdline ) gives more legible output. – Barton Chittenden Mar 1 '12 at 20:51

Arg. just read the stack overflow link that Alex Black posted... looks like proc/.../cmdline has the same 4096 character limit. – Barton Chittenden Mar 1 '12 at 21:22

pipe it into 'less' you should have no problems scrolling left and right :)

piping it into less doesn't solve the truncation issue. – Alex Black Mar 2 '12 at 2:16
huh, that worked for me. anyway, it looks like using proc (suggested above) looks like a great solution :) – ejes Mar 2 '12 at 14:37
The problem I hit was that proc is truncated to 4096 characters, did you find a way to get past that limit? – Alex Black Mar 2 '12 at 17:57
