Here is something that I wrote to identify whether a process has been idle for over 30 mins.
Assumptions. The process is attached to a tty. There are some processes which might be over 30 mins, and are idle. But you need to take precaution when using this script. Some of them might be very useful even though they are/have been idle for days. Provide a pid when running the script. Code:
#! /bin/ksh
# idle.ksh
# Find the idle time of a process.
#
# Assumptions:
# Process is attached to a tty.
#
[[ -z "$1" ]] && echo "Usage: $0 pid" && exit 1
[[ "$1" != +([0-9]) ]] && echo "$1 is not a valid pid" && exit 1
PID="$1"
W=$(which w)
PS=$(which ps)
SED=$(which sed)
AWK=$(which awk)
TTY=$($PS -o tty4 $PID)
TTNo=$(echo "$TTY" | $SED -e '/TTY/d')
TIME=$($W | $SED -n -e "/pts\/$TTNo/p" | $AWK '{ print $5 }')
echo $PID has been idle for $TIME
[[ $TIME = *day* ]] && echo "Killing $PID" && kill -9 $PID && exit 0
IDLE=${TIME%%:*}
[[ $IDLE -gt 30 ]] && echo "Killing $PID" && kill -9 $PID && exit 0
