Very good recommendation for the O'Reilly books on unix and Linux above. When you realise that the core subject matter can be condensed into a single paperback then it is much easier to comprehend.


Regarding command syntax. Unfortunately there are only 26 letters in the alphabet. Within unix syntax you may find that "-f" refers to "force" (say in the context of the "rm" command) or just the name of a file "-f filename" in the context of the "tar" command. This is where the "man" pages and a decent book are so useful.

You'll get used to it.

The one thing newcomers to unix find most difficult is the first principle of unix commands: "when the command has worked, say nothing".

This can be disturbing if you have been used to command languages which have to tell you that they have done a task.
To balance this many unix commands have the "-v" (verbose) switch to tell you that something happened. I rarely ever use it because I like the silence of unix.



If you have a command or a concept which you do not understand, please do post you question on this forum.


Code:
echo "I do not understand"|cut -d" " -f1-2,4

I do understand

qmotifstyle

QMotifStyle(3qt)														  QMotifStyle(3qt)

NAME

       QMotifStyle - Motif look and feel

SYNOPSIS

       #include <qmotifstyle.h>

       Inherits QCommonStyle.

       Inherited by QCDEStyle, QMotifPlusStyle, and QSGIStyle.

   Public Members
       QMotifStyle ( bool useHighlightCols = FALSE )
       void setUseHighlightColors ( bool arg )
       bool useHighlightColors () const

DESCRIPTION

       The QMotifStyle class provides Motif look and feel.

       This class implements the Motif look and feel. It closely resembles the original Motif look as defined by the Open Group, but with some
       minor improvements. The Motif style is Qt's default GUI style on UNIX platforms.

       See also Widget Appearance and Style.

MEMBER FUNCTION DOCUMENTATION

QMotifStyle::QMotifStyle ( bool useHighlightCols = FALSE )
       Constructs a QMotifStyle.

       If useHighlightCols is FALSE (the default), the style will polish the application's color palette to emulate the Motif way of highlighting,
       which is a simple inversion between the base and the text color.

void QMotifStyle::setUseHighlightColors ( bool arg )
       If arg is FALSE, the style will polish the application's color palette to emulate the Motif way of highlighting, which is a simple
       inversion between the base and the text color.

       The effect will show up the next time an application palette is set via QApplication::setPalette(). The current color palette of the
       application remains unchanged.

       See also QStyle::polish().

bool QMotifStyle::useHighlightColors () const
       Returns TRUE if the style treats the highlight colors of the palette in a Motif-like manner, which is a simple inversion between the base
       and the text color; otherwise returns FALSE. The default is FALSE.
