I have several files (around 50) that have the similar format. I need to extract the 5th line from every file and output that into a text file. So far, I have been able to figure out how to do it for a single file:
$ awk 'NR==5' text1.txt > results.txt
OR
$ sed -n '5p' text1.txt > results.txt... (6 Replies)
This code works perfect when using a machine with only one interface online. (Excluding the loopback of course) But when I have other interface up for vmware or a vpn the output gets mixed up. I know I had this working when I was just reading ip's from files so I know it is not a problem with... (8 Replies)

GM,
I have an issue at work, which requires a simple solution. But, after multiple attempts, I have not been able to hit on the code needed.
I am assuming that sed, awk or even perl could do what I need.

Hi,
I have a huge list of archives (.gz). Each archive is about 40MB. A file is generated every minute so if I want to analyze the data for 1 hour I get already 60 files for example.
These are text files, ';' separated, each line having about 300 fields (columns).
What I need to do is to... (11 Replies)
I need your help to discover missing elements for each box.
In theory each box should have 4 items: ITEM01, ITEM02, ITEM08, and ITEM10.
Some boxes either have a missing item (BOX02 ITEM08) or might have da duplicate item (BOX03 ITEM02) and missing another one (BOX03 ITEM01).

XdbeGetVisualInfo(3X11) X FUNCTIONS XdbeGetVisualInfo(3X11)NAME
XdbeGetVisualInfo - Get dbe Visual Informations
SYNOPSIS
#include <X11/extensions/Xdbe.h>
XdbeScreenVisualInfo *XdbeGetVisualInfo(
Display *dpy,
Drawable *screen_specifiers,
int *num_screens)
DESCRIPTION
This function returns information about which visuals support double buffering. The argument num_screens specifies how many elements there
are in the screen_specifiers list. Each drawable in screen_specifiers designates a screen for which the supported visuals are being
requested. If num_screens is zero, information for all screens is requested. In this case, upon return from this function, num_screens
will be set to the number of screens that were found. If an error occurs, this function returns NULL, else it returns a pointer to a list
of XdbeScreenVisualInfo structures of length num_screens. The nth element in the returned list corresponds to the nth drawable in the
screen_specifiers list, unless num_screens was passed in with the value zero, in which case the nth element in the returned list corre-
sponds to the nth screen of the server, starting with screen zero. The XdbeScreenVisualInfo structure has the following fields:
int count
XdbeVisualInfo *visinfo
count specifies the number of items in visinfo. visinfo specifies a list of visuals, depths, and performance hints for this screen.
The XdbeVisualInfo structure has the following fields:
VisualID visual
int depth
int perflevel
visual specifies one visual ID that supports double-buffering. depth specifies the depth of the visual. perflevel is a performance hint.
The only operation defined on a perflevel is comparison to a perflevel of another visual on the same screen. The visual having the higher
perflevel is likely to have better double-buffering graphics performance than the visual having the lower perflevel. Nothing can be
deduced from the following: the magnitude of the difference of two perflevels, a perflevel value in isolation, or comparing perflevels from
different servers.
ERRORS
BadDrawable
One or more values passed in screen_specifiers is not a valid drawable.
