You can use the ps command to see what processes you’re running.
If you’re not sure what processes you’re running, use the ps command to see what you’re up to:
% ps PID TT STAT TIME COMMAND 15047 r5 S 0:00 -csh (tcsh) 15052 r5 S 0:00 xcalc 7648 s6 S 0:00 -csh (tcsh) 15058 s6 R 0:00 ps
This tells me that I’m running two shell programs and one xcalc window. ps also tells me that I’m running ps.
The caveat is that ps doesn’t know about everything you’re doing. For example, right now the most resource-intensive program I’m running is FrameMaker, but ps didn’t tell me about it. It also didn’t mention the xbiff program I’m running. The reason is that I exited the xterm window I started these programs in, and ps usually only displays processes associated with a terminal.
ps is very system-specific. The options on your system may vary, but on my system, I can use the -x command-line option to find all processes on the system that belong to me:
% ps -x PID TT STAT TIME COMMAND 3323 ? S 0:17 xlbiff 7628 ? I 0:00 in.rshd 7629 ? I 0:00 tcsh -c xterm -display opal:0 14869 ? S 0:10 /usr/local/frame/bin/sunxm.os.sparc/maker 14875 ? I 0:00 /usr/local/frame/bin/sunxm.os.sparc/ fm_misd -r 8 -w 11 -v 0 14878 ? I 0:00 /usr/local/frame/bin/sunxm.os.sparc/ fm_flb 15039 ? I 0:00 in.rshd 15040 ? I 0:00 tcsh -c xterm -display opal:0 15047 r5 I 0:00 -csh (tcsh) 15052 r5 I 0:00 xcalc 7648 s6 S 0:00 -csh (tcsh) 15071 s6 R 0:00 ps -x
