how to grep the process running more than 30 days only?

ahpin · 08-18-2009, 09:30 PM

is there a way for me to grep the process that running more than 30 days only using linux command or script?

example:
i do ps -ef to list out the process, then i want to filter only the process that always running more than 30 days..

first, look thru all the output formatting options for "ps". I started with "ps -e -o start". Once you have the right format, you can sort, grep, etc.

grep by itself just looks for keywords (or regexes).

ps aux | grep -w <process name>| grep -v grep | ps -o pid,etime,cmd `awk '{ print $2 }'`

i'm using above command to grab the process and manage to get something like below.

11722 31-16:32:15 <command line>
11723 31-16:32:15 <command line>
11739 31-16:32:15 <command line>
6829 28-10:43:13 <command line>
6830 28-10:43:13 <command line>
6845 28-10:43:12 <command line>

Anyway,is there a way for me to just grab the day more than 30 in this case?

Also, i tried to put this into the script variable, but there is error...
example as below is nto working:
pid=ps aux | grep -w <process name>| grep -v grep | ps -o pid,etime,cmd `awk '{ print $2 }'`

any advice is appreciated...

Please give us the error that's being produced -- that'd help diagnose where the problem is occurring.

Plus, I'm speculating that you may be able/needing to involve the `date` command but this is pure speculation. Just show us the error you get, first.

EDIT: looks like you're missing a pipe or a comma, before the awk command.

Um, guys (of either gender), since it's Linux, how about this?

Code:

find /proc -maxdepth 1 -name '[0-9]*' -mtime +30 | sed 's/^......//'

Sure

if it works for the OP, great! There's usually more than one way to 'skin a cat running Linux'.

if i just execute the command from the shell, it is working...but when i put into the the script, it is showing the error...i think it might be related to the quote use but i just can't figured out which one

pg009> ./getoldprocess.sh
./getoldprocess.sh: line 5: { print $2 }: command not found
pg009>

i=`ps aux | grep -w run | grep -v grep | ps -o pid,etime `awk '{ print $2 }'` `

Code:

i=$(ps aux | grep -w run | grep -v grep | ps -o pid,etime `awk '{ print $2 }'` )

Try the above, for the heck of it. But I still think you're missing a pipe.
