Get X window id from process in bash

问题

Is there any bash tool/warper that could tell which x window(s) has been created by specific process ?

回答1:

wmctrl -lp

gives me the windows and their PIDs. Sample output:

0x04c00022  0 2168   ciro ciro.santilli - Skype™
0x03c00014  0 2154   ciro Krusader
0x03200022  0 2181   ciro Guake!
...

As mentioned, you can use command line tools like wmctrl or xprop. Well behaved clients should set _NET_WM_PID property to be pid of the process which created main window (all popular toolkits do this for you). Note that some clients don't set it or may be on another physical machine (you can use WM_CLIENT_MACHINE property) - so use this information as a hint and don't rely on it to be present or accurate. See emwh spec at freedesktop for reference.

Here are several X11 window management solutions (including one to this problem).

To get the ID of a window by its process ID, use wmctrl in the following way:

#!/usr/bin/env bash
# getwindidbypid
# 
# Get the ID of a window by PID (if the process has a window).
# 
# Usage:
#   getwindidbypid <PID>
# 

while IFS= read line; do
  if [[ "${line}" =~ (0x)([0-9a-z]+)([ ][- ][0-9]+[ ])([0-9]*) ]]; then
    winId="${BASH_REMATCH[1]}${BASH_REMATCH[2]}"
    pid="${BASH_REMATCH[4]}"
    if [[ "${pid}" -eq "${1}" ]]; then
      WIND_IDS+=("${winId}")
    fi
  fi
done < <(wmctrl -lp)

if [ "${#WIND_IDS[@]}" -gt 0 ]; then
  echo "${WIND_IDS[0]}"
fi

Example:

user ~ $  getwindidbypid 37248
0x05a00012
