Good evening. I have absolutely no idea as how to do this & I admit that I do not know anything in unix. I must learn this one of these days.
Im a help desk incharge today & someone gave me this file to be formatted & I have a file like this.
Code:
vi NewFile.txt
232 Users In the forum on 12212010 on Machine KCYKCK
12 Users validating on 12312010 since morning on machine STLSTL
82 Users browsing on 02022011 At 12 Am on POMCMMC
23222 The number of people on 02182011 on machine RRUDJD
and would like to see the output as follows -
Code:
232, Users In the forum on, 12212010, on Machine KCYKCK.
12, Users validating on, 12312010, since morning on machine STLSTL.
82, Users browsing on, 02022011, At 12 Am on POMCMMC
23222, The number of people on, 02182011, on machine RRUDJD.
To be specific, they need the output to be formatted and at the end of each meaningful text (which you folks call as regular expression pattern) there has to be a comma. Now how you define meaningful text is as follows -
The first would always be numbers,
The second would be string(non number value),
The third would be a date value,
The fourth would be another string(non number value),
& finally the machine name.
Although, Im old & totally new to this unix env, I tried the following,
But does not even come close to what is being asked for. I would have been successful with this even if there were text with the same number of column values and unfortunately, the text is not like that
I can sit here & do this the donkey way by going through line by line but as I knew a bit of programming, I thought I could do this in unix but Im scratching my head off on this one.
Any help is appreciated.
Btw, Is it even possible ? Show me the way
regards,
Tan.

shutdown
SHUTDOWN(8) shutdown SHUTDOWN(8)NAME
shutdown - Halt, power-off or reboot the machine
SYNOPSIS
shutdown [OPTIONS...] [TIME] [WALL...]
DESCRIPTION
shutdown may be used to halt, power-off or reboot the machine.
The first argument may be a time string (which is usually "now"). Optionally, this may be followed by a wall message to be sent to all
logged-in users before going down.
The time string may either be in the format "hh:mm" for hour/minutes specifying the time to execute the shutdown at, specified in 24h clock
format. Alternatively it may be in the syntax "+m" referring to the specified number of minutes m from now. "now" is an alias for "+0",
i.e. for triggering an immediate shutdown. If no time argument is specified, "+1" is implied.
Note that to specify a wall message you must specify a time argument, too.
If the time argument is used, 5 minutes before the system goes down the /run/nologin file is created to ensure that further logins shall
not be allowed.
OPTIONS
The following options are understood:
--help
Prints a short help text and exits.
-H, --halt
Halt the machine.
-P, --poweroff
Power-off the machine (the default).
-r, --reboot
Reboot the machine.
-h
Equivalent to --poweroff, unless --halt is specified.
-k
Do not halt, power-off, reboot, just write wall message.
--no-wall
Do not send wall message before halt, power-off, reboot.
-c
Cancel a pending shutdown. This may be used cancel the effect of an invocation of shutdown with a time argument that is not "+0" or
"now".
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
