BASH I/O stdout, stdin, and stderr

Some times we don’t want that command print out messages, and we need to clean all out messages (error or standard out) that it generates. For to solve this, we are going to use the I/O facility provided by BASH.

BASH provide 3 file descriptors, and they are:
0 – stdin – Used for get data.
1 – stdout – Used for write standard data into screen.
2 – stderr – Used for write error messages into screen.

So, using redirector (>) we can redirect(obviously) this data/messages wherever we want and also files.

Examples:
¿How to redirect error messages(stderr) to standard out(stdout)?

ls this.file.doesnt.exist 2>&1

¿How to redirect error messages(stderr) to limbo(/dev/null)?

ls this.file.doesnt.exist 2> /dev/null

¿How to redirect error(stderr) and standard out(stdout) messages to limbo?

ls this.file.doesnt.exist &> /dev/null
or
ls this.file.doesnt.exist 2> /dev/null 1>&2

DAHDI Linux 2.1.0.4 with OSLEC

Today I was installing DAHDI Linux 2.1.0.4 with OSLEC support and this is my little experience with it…

I needed modify drivers/dahdi/Kbuild

# Only enable this if you think you know what you’re doing. This is not
# supported yet:
obj-m += dahdi_echocan_oslec.o
#
# A quick and dirty way to build OSLEC, if you happened to place it
# yourself in the dahdi source tree. This is experimental. See README
# regarding OSLEC.
#obj-m += ../staging/echo/
obj-m += ../staging/echo/echo.o

After I did it, I needed copy echo directory from the kernel linux-2.6.28.7 sources indahdi-linux-2.1.0.3/drivers/staging

cd dahdi-linux-2.1.0.3/
mkdir drivers/staging
cp -r /usr/src/linux-2.6.28.7/drivers/staging/echo drivers/staging

So… I installed the package and enabled the card with OSLEC echo canceller.

If you want to transform some pixmap image into vector, this is a tool for convert it into vector format.
