Full Discussion: Find Memory and activity from command output

With grep's greedy regex matching its not easy to lay hands on the activity if its "name is after "/opt/rather/". There may be better solutions than these ones that rely on the input lines' structure. Try
Code:
ps -eo pid,etime,command | grep -o "/opt/rather/[^ /]*\|-Xmx[^ ]*" | uniq | grep -A1 "\-Xmx"
-Xmx2048M
/opt/rather/bar
-Xmx3002M
/opt/rather/raal

or

Code:
ps -eo pid,etime,command | grep -o "\-Xmx[0-9M]* *-cp[ .:]*/opt/rather/[^/]*"  | grep -o "\-Xmx[0-9M]*\|[^ /]*$" | paste -s -d"\t\n"
-Xmx2048M    bar
-Xmx3002M    raal

or
Code:
ps -eo pid,etime,command | grep -o "\-Xmx[0-9M]*.\{,30\}/opt/rather/[^ /]*" | grep -o "\-Xmx[0-9M]*\|[^ /]*$" | paste -s -d"\t\n"
-Xmx2048M    bar
 -Xmx3002M    raal


A small awk script might be more apt to fulfill your needs to the full extent...
