Working in a bash environment, in the following example, how do I direct the error message that putting in an invalid flag (-j for example) would normally produce to dev/null?
while getopts "abcd" opt
do
case "$opt" in
i) a etc ;;
r) b etc ;;
f) c etc ;;
v) d etc ;;
\?) direct actual error message to dev/null
Consider:
#!/bin/sh
#this is a shell script in sh (bourne)
grep missingfile 2>errout.txt
It works from the command line, but keeps producing errors from the script. So how do I redirect in a bash shell...or bourne? (3 Replies)
Hi
i am running oracle database import through a script and script scans the import log to see if there are any errors.
Now the porblem is that when i run the script the import log appears on the screen even if i direct the output of import to /dev/null.

Hello,
When I run the following program:
ssh 192.168.1.4 bash -l <<EOF

I get the following confusing error.

How are these two different? They both prevent output and error from being displayed. I don't see the use of the "&"
echo "hello" > /dev/null 2>&1
echo "hello" > /dev/null 2>1 (3 Replies)
I apologize if this question has been answered else where or is too elementary.
I ran across a KSH script (long unimportant story) that does this:
if ; then
CAS_SRC_LOG="/var/log/cas_src.log 2>&1"
else
CAS_SRC_LOG="/dev/null 2>&1"

I've a script with some output redirect to /dev/null,

Hi there,
I need to execute a command in the bash. The program prints some standard (output and) error and then wants the user to choose one of several options and type the according input. I am trying to solve this issue in a bash script but also running into some circular dependency. How can I... (7 Replies)

lua-oocairo-fontopt - options controlling text rendering
Introduction
A font options object contains options that tell Cairo how to render text on surfaces. They can be created with the "font_options_create"
function in the main oocairo module (see lua-oocairo(3)), and retrieved from scaled fonts or context objects with "get_font_options"
methods.
Font options objects can be compared with the "==" operator. Two different objects with the same options set will be considered equal.
Methods
The following methods are available on font options objects:
opt:copy ()
Returns a new font options object, with identical options to opt. The two objects will be completely independent, so you can set them
to have different options.
opt:get_antialias ()
Get the current antialiasing mode, which will be one of the strings accepted by the "opt:set_antialias()" method.
opt:get_hint_metrics ()
Returns the current hint metrics option, which will be one of the same strings accepted by the "opt:set_hint_metrics()" method.
opt:get_hint_style ()
Get the kind of font hinting done when rendering text. Returns one of the strings accepted by the "opt:set_hint_style()" method.
opt:get_subpixel_order ()
Returns the current ordering of colour components in pixels used for subpixel rendering, which will be one of the same strings accepted
by the "opt:set_subpixel_order()" method.
opt:hash ()
Return a number which can be used as a hash key identifying the particular options in opt. That is, if you wanted to cache fonts
according to the options set on them, you could store them in a table with this hash value as the key. Two font options objects with
the same options will have the same hash value.
opt:merge (srcopt)
Add any options which are set to a non-default value in srcopt to opt if that still has the default value from them. The options in
srcopt will be unchanged. Nothing is returned.
opt:set_antialias (antialiastype)
Set the antialiasing mode used for drawing. The argument must be a string or boolean value accepted by the "set_antialias" method on
context objects (see lua-oocairo-context(3)).
opt:set_hint_metrics (hintmetrics)
Set the kind of hinting to be applied to the metrics, as opposed to outlines, of the glyphs in a font. The hintmetrics value must be
one of the following strings:
default
off
on
opt:set_hint_style (hintstyle)
Set the kind of font hinting done when rendering text. The hintstyle value must be one of the following strings:
default
none
slight
medium
full
opt:set_subpixel_order (order)
Used to inform Cairo of the arrangement of colour components in the pixels of a display device like a monitor. Only applies if
subpixel antialiasing is used. The order value must be one of the following strings:
default
rgb
bgr
vrgb
vbgr
The last two options refer to vertical arrangements of colours.
