a Python version of "pidof" on Solaris

gtaww

I copied from other place and it's a very useful tool.

=================================================
#!/usr/bin/env python
import os
import sys
import re

if len(sys.argv) != 2:
    #print >> sys.stderr, "Provide one (and one only) pattern to match."
    sys.exit(1)

ps = os.popen('ps -e')

ps.readline() #-- To eliminate initial line
for line in ps:
    try:
        match = re.search(r"%s" % (sys.argv[1],), line, re.IGNORECASE)
    except re.error:
        match = None
        sys.exit(1)
    if match != None:
        print re.search(r"^\s*?(\d+)(?=\s)", line).group(1)

我觉得这样就可以满足需要了。

bash-2.05$ more ~/perl/pidof
#!/bin/sh
if [ $# -ne 1 ]
then
echo "usage: $0 yourcommand"
exit 1
fi
ps -A | grep $1 | awk '{print $1}'
