Try piping the output of ps to less or another pager that can scroll horizontally. - Andrew matador matador wrote:
I saw a strange behaviour on "ps" and on "top" output in Mac OS X 10.4.9 Version. Let's see how it is: rfc-1918:~ xxx$ ps aux > ps_output rfc-1918:~ xxx$ cat ps_output USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND xxx 587 8.0 5.4 185848 28488 ?? S 2:55PM 7:20.43 /Applications/iTune xxx 196 0.7 2.0 186176 10324 ?? S 11:04AM 2:36.06 /Applications/Utili . . we can see that "ps" doesn't print completely the path. So if we pipe the "ps" with "grep" something if the path it's long we can find the specific process. rfc-1918:~ xxx$ cat ps_output | grep iTunes rfc-1918:~ xxx$ cat ps_output | grep iTune xxx 587 8.0 5.4 185848 28488 ?? S 2:55PM 7:20.43 /Applications/iTune xxx 185 0.0 0.2 124980 880 ?? S 10:26AM 0:00.22 /Applications/iTune If we let the terminal window wider we are still limited by monitor width. Linux user would like to use "top" command...but... 60 coreservic 0.0% 0:03.27 3 114 163 924K 11.7M 2.95M 40.3M 57 WindowServ 5.1% 9:54.91 2 343 646 5.82M- 32.7M- 33.6M- 242M- 50 DirectoryS 0.0% 0:01.10 4 65 40 372K 1.01M 1.09M 30.1M we can see that "top" have the same problem, it truncates the process name. These issues open an user-space rootkit scenario.
