Here's how I personally would do it (I'm not trying to do it all for you, I just think that there's so many ways to do it - this may give you a few new ideas to tackle your own script):
Did you catch what happened with the "logg" variable? It's important to have a space after "not", to seperate the words. Also, this script does not check to see if that username even exists... it will simply say that the user is not logged in, since there is no GECOS data...
One more thing: I added another cut statement, because my GECOS info is comma delimited - the way the script was before, I was seeing the entire field, not just that name.

Hi Everyone,
i have a string 00:44:40
so:
$tmp=~ s/://gi;
$tmp=~s/({2})({2})({2})/$1*3600+$2*60+$3/e;
the output is 2680.
Any way to combine this two lines into a single line?
Thanks (4 Replies)
I am learning to build from SVN and other tools, with a lot of copying and pasting from forums. I like to append && echo "success" to all commands so that I can see at a glance if things went all right. Is there a way that I can have the bash shell append this to all commands?
Thanks! (5 Replies)
Hi - Within perl I want to execute a system command. I want to re-direct all the output from the command to a file (@result = `$cmd`;), but I ALSO want the results to be displayed on the screen (system("$cmd");
The reason is this - if the command completes, I want to process the output. If the... (6 Replies)

In the awk below, what I am attempting to do is check each line in the tab-delimeted input, which has ~20 lines in it, for a keyword
SVTYPE=Fusion. If the keyword is found I am splitting $3 using the . (dot) and reading the portion before and after the dot in an array a.
If it does have that... (12 Replies)
I have been searching and trying to come up with an awk that will perform the following on a

combinediff
COMBINEDIFF(1)COMBINEDIFF(1)NAME
combinediff - create a cumulative unified patch from two incremental patches
SYNOPSIS
combinediff [-p n] [-U n] [-d PAT] [-Bbiqwz]
[--interpolate | --combine] diff1 diff2
combinediff {--help | --version}
DESCRIPTION
combinediff creates a unified diff that expresses the sum of two diffs. The diff files must be listed in the order that they are to be
applied. For best results, the diffs must have at least three lines of context.
The diffs may be in context format. The output, however, will be in unified format.
OPTIONS -p n When comparing filenames, ignore the first n pathname components from both patches. (This is similar to the -p option to GNU
patch(1).)
-q Quieter output. Don't emit rationale lines at the beginning of each patch.
-U n Attempt to display n lines of context (requires at least n lines of context in both input files). (This is similar to the -U option
to GNU diff(1).)
-d pattern
Don't display any context on files that match the shell wildcard pattern. This option can be given multiple times.
Note that the interpretation of the shell wildcard pattern does not count slash characters or periods as special (in other words, no
flags are given to fnmatch). This is so that ``*/basename''-type patterns can be given without limiting the number of pathname com-
ponents.
-i Consider upper- and lower-case to be the same.
-w Ignore whitespace changes in patches.
-b Ignore changes in the amount of whitespace.
-B Ignore changes whose lines are all blank.
-z Decompress files with extensions .gz and .bz2.
--interpolate
Run as ``interdiff''. See combinediff(1) for more information about how the behaviour is altered in this mode.
--combine
Run as ``combinediff''. This is the default.
--help Display a short usage message.
--version
Display the version number of combinediff.
BUGS
The -U option is a bit erratic: it can control the amount of context displayed for files that are modified in both patches, but not for
files that only appear in one patch (which appear with the same amount of context in the output as in the input).
