Thank you Don Cragun and Aia for your reply. That's exactly what I was looking for.

@Don Cragun - My actual file list looks like this:

Code:
 sample-test~1.lg.15-05-25_20:41:05.20150611
 sample-test~1.lg.*
 sample-test~1.lg.15-05-27_20:28:32.20150611
 sample-test~1.lg.15-05-26_20:29:40.20150611
 sample-test~1.lg.20160431.lg
 sample-test~1.lg.20150301.lg
 sample-file~df_gp~1.lg.20150616
 sample-test~1.lg.20150616
 sample-test~1.lg.15-05-28_20:28:27.20150616
 sample-test~1.lg.15-05-27_20:28:32.20150616
 sample-test~1.lg.15-05-26_20:29:40.20150616
 sample-test~1.lg.15-05-25_20:41:05.20150616
 sample-bat-test~1.lg.20150616

So, inline with the example given by you, I managed to filter out the ones with timestamp by using ls -1 sample* | grep -v '[:]' and obtained the below:

Code:
sample-bat-test~1.lg.20150616
sample-test~1.lg.*
sample-test~1.lg.20150301.lg
sample-test~1.lg.20150616
sample-test~1.lg.20160431.lg
sample-file~df_gp~1.lg.20150616

I want to create empty files of all the ones without a timestamp so tried doing this but doesn't seem to work:

Code:
for fn in `ls -1 sample* | grep -v '[:]'`
do
touch fn
done

Could you please tell me where I've gone wrong?

glgetmultisamplefv

GLGETMULTISAMPLEFV(3G)						    OpenGL 3.3						    GLGETMULTISAMPLEFV(3G)

NAME

       glGetMultisamplefv - retrieve the location of a sample

C SPECIFICATION

       void glGetMultisamplefv(GLenum pname, GLuint index, GLfloat *val);

PARAMETERS

       pname
	   Specifies the sample parameter name.  pname must be GL_SAMPLE_POSITION.

       index
	   Specifies the index of the sample whose position to query.

       val
	   Specifies the address of an array to receive the position of the sample.

DESCRIPTION

       glGetMultisamplefv queries the location of a given sample.  pname specifies the sample parameter to retrieve and must be
       GL_SAMPLE_POSITION.  index corresponds to the sample for which the location should be returned. The sample location is returned as two
       floating-point values in val[0] and val[1], each between 0 and 1, corresponding to the x and y locations respectively in the GL pixel space
       of that sample. (0.5, 0.5) this corresponds to the pixel center.  index must be between zero and the value of GL_SAMPLES - 1.

       If the multisample mode does not have fixed sample locations, the returned values may only reflect the locations of samples within some
       pixels.

ERRORS

       GL_INVALID_ENUM is generated if pname is not one GL_SAMPLE_POSITION.

       GL_INVALID_VALUE is generated if index is greater than or equal to the value of GL_SAMPLES.
