csh script for deleting extra spaces in text file
I am new to scripting and I needed to know if there would be an easy way to delete extra spaces in a text file. I have a file with three rows with 22 numbers each, but there is extra spaces between the numbers when it gets output by this program AFNI that I am using. What script would help delete the extra spaces so that there is only one space between numbers? The thing is, the numbers aren't all evenly spaced in the rows....

Thanks in advance...

Megan

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.
