osd_cat

XOSD(1xosd)															       XOSD(1xosd)

NAME

       osd_cat - X on-screen file displayer

SYNOPSIS

       osd_cat [OPTION] [FILE]...
       osd_cat -b percentage|slider [OPTION]

DESCRIPTION

       Display FILE, or standard input, on X screen.

       -p, --pos=POS
	      This option tells osd_cat where to display the text. POS can be top, middle, or bottom. The default is top.

       -o, --offset=OFFSET
	      This option specifies the offset from the top or bottom of screen the text is displayed. The default is 0.

       -A, --align=ALIGN
	      This option tells osd_cat where to display the text. ALIGN can be left, right or center. The default is left.

       -i, --indent=OFFSET
	      This option specifies the INDENT from the left of screen the text is displayed. The default is 0.

       -f, --font=FONT
	      This option specifies the FONT to be used for displaying the text. The default is fixed.

       -c, --color=COLOR
	      This option specifies the COLOR to be used for displaying the text. The default is red.

       -d, --delay=TIME
	      This option specifies the number of seconds the text is displayed. The default is 5 seconds.

       -l, --lines=LINES
	      This option specifies the number of LINES to scroll the display over. The default is 5.

       -s, --shadow=OFFSET
	      This option specifies the OFFSET of the text shadow. The default is 0, which means no text shadow is created.

       -a, --age[=SCROLL_AGE]
	      This  option  affects  screen  redrawing.  If SCROLL_AGE seconds pass before a new line is ready (for example, you're reading from a
	      pipe), all lines are cleared at once instead of being scrolled off as new lines replace old lines. The default is 0.
	      When no SCROLL_AGE is explicitly given, the current value from DELAY is used.

       -w, --wait
	      This option also affects screen redrawing. When there is data ready to be put on screen, this option  will  cause  osd_cat  to  wait
	      until the display is clear. An alternative to scrolling.

       -b, --barmode=TYPE
	      Lets  you  display a percentage or slider bar instead of just text.  TYPE may be percentage or slider.  In this mode no text is read
	      from any file, but the following options can be used:

       -P, --percentage=PERCENTAGE
	      This option specified the position of the percentage / slider bar.  PERCENTAGE may be in the range from 0 to 100, the default is 50.

       -T, --text=TEXT
	      This option specifies an optional TEXT which gets displayed above the percentage bar.  The default is empty, so no  additional  text
	      is displayed.

       -h, --help
	      display help (which is often more up to date) and exit

       With no FILE, or when FILE is -, read standard input.
