osd_cat
XOSD(1) General Commands Manual XOSD(1)
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.
-S, --shadowcolour=COLOUR
This option specifies the COLOUR of the text shadow. The default is black.
-O, --outline=WIDTH
This option specifies the WIDTH of the text outline. The default is 0, which is no outline.
-u, --outlinecolour=COLOUR
This option specifies the COLOUR of the text outline. The default is black.
-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.
