comment why i can see ipv6 socket with ipv6 stack disable?
Yeah, no worries. You may get an answer here anyway ;-). (You won't get any friends by post Q to multiple sites. Also review ipv6 Qs at another Stackexchange site : http://serverFault.com. Good Q, but just not appropriate here (IHMO). Good luck.

comment How to convert Ubuntu init script to Amazon Linux AMI init script?
are you saying that your latest version with echo $PID > $PIDFILE doesn't work? Are you sure there is a value for $PID. Add an echo PID=$PID to debug.. Otherwise, look at the permissions to your /var/run dir where you are writing the $PIDFILE. the process that is running the script must have write privileges in bot /var and /var/run. Good luck.

comment Crontab in Daylight Savings
Interesting, but not really a programming problem. Suggest you flag and ask moderator to move to linux.stackexchange.com. Good luck!

comment Linux: Does find | xargs grep have limitations?
someone else posted this problem in the last 2-3 days. Sorry don't have time to search for it. Might help to add uname and find --version ; xargs --version ;grep --version output to your posting. (But I'm guessing spaces in path names). Good luck.

doah! I remove my hare-brained comment. (I didn't know it was possible to move stuff above/beyond '/'. ) Good luck to all.

comment How to adjust numeric fields in a text file
I'm almost sure there are 64bit versions of gawk available. What you describe in your comment sounds like the 32bit version, but I don't have time to research now. Good luck.

I think this should be part of your question. Looks to me like you've got the problem solved. Good luck.

comment Detailed Per-Process Profiling
depending on the version of ps and the options available, some of that information is available there. But... yes, I would love for an all-inclusive performance console like found on Windows7. One possible thing to help ... there is a pretty darn comprehensive perf utility originally for AIX (IBM Unix) called NMON, which I believe has been ported for use on (some) linux(es). Good luck.

comment Time validation with regex
I think you're on the right track using case expressions, but you don't understand the rules of the character class expressions, i.e. [0-23] means "only 1 char matching" either 1). the range 0-2 (i.e. 0,1,2) OR 2) the single number number 3, NOT 0 hrs to 23 hrs as I'm guessing you mean. ---- Inside sq-brackets, each char stands for itself as a match for one char, excepting when the range notation is use as 0-2. You can use reg expers in this case to get mostly what you want, ie case TIME in [0-2][0-9]\ :[0-5][0-9]). Read it one sq-brkt at a time, what ever inside is a single match. GL.

comment what do you mean by interactive shell?
ksh is also a modern shell :-) See www2.research.att.com/sw/download and use the menu on the left-hand margin to navigate to AST->ksh->overview. A new release comes out several times a year from David Korn and Glen Fowler. Good luck to all.

comment Can sed be used to generate a load file for my date lookup fact table?
most sqls have a dateadd(), datediff() and similar functions that make this very easy to compute. It may be possible to do this in sed, but would be torture to create and a fireable offence at most organization to check it in as code that someone else may have to maintain ;-)! Good luck.
