Hi
I have a doubt, how can I know what process are run by an user?
I tried:
ps aux | grep username but since one of the running process (with hundred of thread) its running in a folder similar than the user name, it list me tons of process.
Ex: Username: test
thousand of threads running in ex: /var/test


How can I cut the list to only show me the process that "test" its running?

Something like

ps auxU username

?

Hi Alex

I tried that too

Let me show you

# ps auxU tomcat4

The username its tomcat4 but, since all the tomcat intances are running in /var/tomcat403 the ps aux list all the instances, and I want to list only the instances ran by the user tomcat4 :(

Try ps aux|grep ^username

The only problem is, piping seems to truncate the output to 80 columns.

Maybe linux's ps is different from freebsd's in that fashion (somehow):

# ps aux |grep mysql
root 179 0.0 0.0 644 252 con- I Wed07AM 0:00.01 /bin/sh /usr/local/bin/safe_mysqld
mysql 199 0.1 1.5 32800 15836 con- S Wed07AM 6:14.57 /usr/local/libexec/mysqld --basedir
# ps auxU mysql
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
mysql 199 0.0 1.5 32800 15836 con- S Wed07AM 6:14.60 /usr/local/libexec/mysqld --basedir=/u
# ps aux |grep ^mysql
mysql 199 0.1 1.5 32800 15836 con- S Wed07AM 6:14.96 /usr/local/libexec/mysqld --basedir

The U is supposed to show all processes belonging to mysql. Try 'ps uU tomcat4', see if that helps? Maybe the a is throwing it off...?

# ps uU mysql
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
mysql 199 0.4 1.5 32800 15836 con- S Wed07AM 6:15.16 /usr/local/libexec/mysqld --basedir=/u

Thanks Alex

ps uU tomcat4 worked great :)!
Thanks a lot.
