Removing Columns From Output

darthtux · 08-01-2004, 03:33 AM

When I run the ps -ef command I get output. One line is:

Code:

user 12822     1  0 Jul31 ?        00:00:00 kalarmd -session 10a862bbf000106887608500000026650004

Now I need to remove everything to the right of the TIME column leaving only the CMD column.

So what will be left is

Code:

kalarmd -session 10a862bbf000106887608500000026650004

There are different numbers of columns for the processes on the right but I need all that.

Anyone know how to do this?

ps -eo cmdline

That *should* just spit out the full command line.

Remove the red part to make it work:

Code:

ps -eo cmd

Thank you very much. That worked.

Now how to I get only the first column or only the user? What I am trying to do is take the output of ps -ef *before* and *after* reboot (into two files), have only the user and cmd info from each file, do a diff and then paste. The resulting output being the difference in the two files. The PID's etc. will change so I only want to diff and paste the user and cmd info.

Then it's:

Code:

ps -eo user,cmd

You will likely have to sort prior to diffing.
