Top Forums UNIX for Beginners Questions & Answers Getting the current time from a website and parsing date Post 303008826 by Scott on Wednesday 6th of December 2017 05:44:19 PM

Does it work? Not really. Without a field separator, $6 is the whole time (h:m:s). $6 * 60^2 does give the right answer for the hours (75600 seconds), with a little help from awk, but $8 and $9 are empty fields, so you won't get the minutes or seconds using that. There are a number of ways you can take the time (h:m:s) and split in into its component parts. Changing the field separator is one, the substr function is another, but doing nothing won't give you the right answer.

Without any field separator, your input looks like this:
Code:
$1    $2   $3 $4  $5   $6       $7     $8     $9

grab-account

GRAB-ACCOUNT(8) 						 chiark utilities						   GRAB-ACCOUNT(8)

NAME

       grab-account - add new account synchronised to remote system

SYNOPSIS

       grab-account local-user source [remote-user]

DESCRIPTION

       grab-account  reconfigures  sync-accounts  to  start synchronising a specified local user (which may not yet exist) from a specified remote
       system, and then invokes sync-accounts once to synchronise from that source.

       /etc/sync-accounts/createuser should contain a addhere line in the appropriate source section (ie, after host source).  grab-account adds a
	 user local-user [remote=remote-user]
       directive just before addhere and runs sync-accounts source.

EXIT STATUS

       0      All went well.

       any other
	      There were problems.

FILES

       /etc/sync-accounts; See also sync-accounts(8).

ENVIRONMENT

       See sync-accounts(8).

BUGS

       There is no locking of /etc/sync-accounts so do not invoke grab-account from a script, or more than once at a time by hand.   Do  not  edit
       /etc/sync-accounts by hand and also simultaneously run grab-account.

       The mechanism involving addhere is suboptimal.  This should be done with an include feature in sync-accounts, so that grab-account does not
       have to edit a configuration file that really belongs to the sysadmin.
