}

####################################### main

typeset -i nSortKey
case $1 in

  sFlag="-n"
  nSortKey=1
  ;;
2|pid)
  sFlag="-n"
  nSortKey=2
  ;;

  ;;
*)
  showUsage
  exit 0
  ;;
esac

echo "port\tpid\tcmd"
ps -eo pid,comm | while read pid cmd
do
  pfiles $pid 2> /dev/null | grep port: | awk "{printf(\"%s\t%s\t%s\n\",\$5,\"$pid\",\"$cmd\")}"
done | sort $sFlag -u -k $nSortKey 


Wish this helps.

[Level 2] Shell Interactive With Zenity Episode 5 -- list

Image
If you want to give a list for user to choose, you can use the option "--list". The command synopsis as below: SYNOPSIS      zenity  --list [--title=title] [--window-icon=path] [--width=width]    [--height=height] [--timeout=seconds] [--column=text] [--checklist]       [--radiolist] [--separator=character] [--multiple] [--editable] [--print-column=number] [--hide-column=number] Just like " --calendar ", if you press "ESC" key or click button "Cancel", the return code will be "1".

[Level 2] iif in Python

If you want to implement iif in Python, please refer to the following sample code: #!/bin/env python def iif(b): return 'It\'s True' if b else 'It\'s False' print iif(True) print iif(False) And the following sample, guess what will you get! #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % 'Ture' if b else 'False' Result: $ ./iif.py b: Ture False The second result is "False", not "b: False". Why??? Because the prededence of string concatenation is higher than if. Therefore you need to use () to make it correct. #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % ('Ture' if b else 'False') Wish this helps. regards, Stanley Huang
