Hello,
I want to make a script which says if a text file is empty or not.

Now I think that the better way is the ls -s solution (considering that an empty text file has a 0 weight, because "cat file.txt" fails when file is... (4 Replies)

gpm.conf
GPM.CONF(5) BSD File Formats Manual GPM.CONF(5)
NAME
gpm.conf -- startup configuration file for gpm
DESCRIPTION
gpm.conf specifies options to be passed to the gpm daemon at start time. It is parsed by the init script, rather than by gpm itself. It
comprises variable assignments in Bourne shell syntax: variable=value (with no extra spaces; to embed spaces or other shell metacharacters in
values, use quotes as in shell scripting). Blank lines and lines beginning with a hash ("#") are ignored.
Settings are implemented by setting flags on the gpm command line; these are documented in gpm(8). The following variable names are speci-
fied:
device Specifies the device file for your primary mouse. This sets -m.
type Specifies the protocol for your primary mouse. This sets -t.
device2, type2
The same as device and type, but for your secondary mouse. These set -m and -t after passing -M. If either of these are
defined, both must be.
responsiveness
Specifies the responsiveness for your primary mouse. This sets -r.
sample_rate Specifies the sample rate for your primary mouse. This sets -s.
repeat_type Enables the gpm repeater and sets the repeater protocol, using the -R flag. Repeat type none or an empty value will disable
the repeater.
append Any options specified here are appended to the gpm command line. If you use multiple options, you will need to enclose the
value in quotes ("").
EXAMPLES
A simple gpm.conf file for a PS/2 mouse whose protocol should be autodetected, and which should be repeated in /dev/gpmdata as a serial Mi-
crosoft Intellimouse:
# Sample gpm.conf
device=/dev/psaux
type=autops2
repeat_type=ms3
This will cause the daemon to be started as gpm -m /dev/psaux -t autops2 -Rms3.
FILES
/etc/gpm.conf
SEE ALSO
gpm(8), dpkg-reconfigure(8). dpkg-reconfigure gpm can be used to generate and update the gpm.conf file automatically.
