Hi

I'm new for this forum and actually, I like this forum for the number of experts members that in the forum.

First, How do I use grep command to grep the contents of more than one file(with any extension!) to be saved in one single file?

For example, I have tried this command grep, but it include the file name too..!! Which i don't want to be included?

The command grep I used:
grep "[0-9]" *.PUN > allpun.out

file1 0001091Y.PUN
file2 0001291X.PUN
file3 0001302T.PUN
...
...
fileN *******.PUN

Output file:
0001091Y.PUN:960109 914 4.54 25- 9.21 40-50.34 14.83 2.81 12 335116.5 0.26 6.8 81.7 D1
0001291X.PUN:940129 559 37.02 24-28.93 39-51.79 0.86 1.99 17 151 9.0 0.07 0.2 0.4 B1
0001302T.PUN:940130 1047 38.93 24-53.89 40-44.31 9.52 2.89 20 321 93.9 0.17 1.6 28.7 D1
0001311V.PUN:940131 843 37.78 24-53.54 40-46.08 5.19 2.88 17 322 96.4 0.21 15.9 49.9 D1

But, I don't want the file name to be included in the output file?
(the file name start at the beginning of each line and followed by a colon ':', then the contents of each file).
How do I do that?

Second, how do I grep only, let's say, a range of Latitude and a range of Longitude from the final output file? (Above)
Then, I want to convert the Lat and Long columns to decimals numbers? without the '-' sign?

For your information, the header of this data files are:
DATE ORIGIN LAT N LONG E DEPTH MAG NO GAP DMIN RMS ERH ERZ QM

But, this header not included for all files?

Looking for any help or point!

And I appreciate your help in advance
