How to find user only process for a spesific program

[Farslan]

Hi,

First of all actually I want to find out the working directory of a process. This can be easily found by

pwdx pid

But to find the pid of the process I have to always check it out via ps. Now i make some research and i found this piece bash code:

echo COMMAND | xargs -ixxx ps -C xxx -o pid= | xargs -ixxx ls -l /proc/xxx/cwd

It shows directly the working directory of the process. But now the problem comes, if there is other users who are using this command i get the error:

4531: Permission denied

This is caused because other users are also running the same process.

Now here comes the question, how can i modify the above code that it shows only process from a specific user( in other words the working directory)

Thanks in advance

Ok i found another way, i've used awk and for loop, this code do the same job

for pid in $(ps -u USERNAME  | grep PROGRAMNAME | awk '{print $1;}'); do pwdx $pid ; done
