linux - How to make a python script run 15 minutes after system startup? -


i wrote script python reminds me open whatsapp web whenever chrome browser opened. run script each time, have use terminal make python script run. want make script run automatically 15-20 minutes after system starts.

here's code:

import webbrowser import os import signal import tkmessagebox subprocess import check_output crontab import crontab   def get_pid(name):     return int(check_output(["pidof","-s",name])) '''script open whatsapp web whenever chrome opened'''  cron=crontab() job=cron.new(command='/usr/bin/echo') job.minute.during(1,50).every(1) name="chrome" if (get_pid(name)):     webbrowser.open('http://web.whatsapp.com')     tkmessagebox.showinfo(title="greetings", message="connect         phone chrome open whatsapp!")

i tried editing crontab, did not prove helpful. there way so?

edit-1 here's updated code, , still doesn't seem work. when manually run script, works, otherwise not(on reboot).

    #!/usr/bin/env python     import webbrowser import os import signal import tkmessagebox subprocess import check_output import time  def get_pid(name):     return int(check_output(["pidof","-s",name]))   '''script open whatsapp web whenever chrome opened'''  name="chrome" while(1):     time.sleep(600)     while(get_pid(name)):         webbrowser.open('http://web.whatsapp.com')         tkmessagebox.showinfo(title="greetings", message="connect phone chrome open whatsapp!")         print "hey"

apart this, added following lines in crontab:

@reboot /usr/bin/python /path/to/whatsapp.py &

further, made .conf file looks :

start on runlevel [2345] stop on runlevel [!2345]  exec /path/to/whatsapp.py

and recent log file looks this:

syntaxerror: invalid syntax traceback (most recent call last):   file "/path/to/whatsapp.py", line 17, in <module>     while(get_pid(name)):   file "/path/to/whatsapp.py", line 10, in get_pid     return int(check_output(["pidof","-s",name]))   file "/usr/lib/python2.7/subprocess.py", line 573, in check_output     raise calledprocesserror(retcode, cmd, output=output) subprocess.calledprocesserror: command '['pidof', '-s', 'chrome']' returned non-zero exit status 1 traceback (most recent call last):   file "/path/to/whatsapp.py", line 20, in <module>     tkmessagebox.showinfo(title="greetings", message="connect phone chrome open whatsapp!")   file "/usr/lib/python2.7/lib-tk/tkmessagebox.py", line 83, in showinfo     return _show(title, message, info, ok, **options)   file "/usr/lib/python2.7/lib-tk/tkmessagebox.py", line 72, in _show     res = message(**options).show()   file "/usr/lib/python2.7/lib-tk/tkcommondialog.py", line 44, in show     w = frame(self.master)   file "/usr/lib/python2.7/lib-tk/tkinter.py", line 2537, in __init__     widget.__init__(self, master, 'frame', cnf, {}, extra)   file "/usr/lib/python2.7/lib-tk/tkinter.py", line 2049, in __init__     basewidget._setup(self, master, cnf)   file "/usr/lib/python2.7/lib-tk/tkinter.py", line 2024, in _setup     _default_root = tk()   file "/usr/lib/python2.7/lib-tk/tkinter.py", line 1767, in __init__     self.tk = _tkinter.create(screenname, basename, classname, interactive, wantobjects, usetk, sync, use) _tkinter.tclerror: no display name , no $display environment variable

where path/to path script.

simple solutions best: make script run on boot, , sleep 15 min.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
