[kostas]

Hello friends,

I have the following txt log file ==>

=================================================================================
[DEBUG] 5/24/07 5:35:50 PM : Finished to read one line : r 250 1006 -63
-65 91 -6 -8 319*

I would like to parse this file with ruby, and to produce a new txt file
where i have only ==>

r 250 1006 -63 -65 91 -6 -8 319*
r 250 1015 -52 -72 91 -6 -8 319*
r 250 1019 -61 -83 92 -7 -8 319*


How can i do that?

r 250 1019 -61 -83 92 -7 -8 319*

Use the right tool(s) for the job:

% cut -f 5 -d: x.txt | grep . | cut -c2-
r 250 1006 -63 -65 91 -6 -8 319*
r 250 1015 -52 -72 91 -6 -8 319*
r 250 1019 -61 -83 92 -7 -8 319*

r 250 1006 -63 -65 91 -6 -8 319*
r 250 1015 -52 -72 91 -6 -8 319*
r 250 1019 -61 -83 92 -7 -8 319*

Who knows if that's going to work right if other output is mixed in?

$ ruby -ne 'puts $1 if /Finished to read one line : (.*)/' x.txt
r 250 1006 -63 -65 91 -6 -8 319*
r 250 1015 -52 -72 91 -6 -8 319*
r 250 1019 -61 -83 92 -7 -8 319*

Presumably the OP.

Hi,

I have the following txt log file ==>

r 250 1006 -63 -65 91 -6 -8 319*
r 250 1015 -52 -72 91 -6 -8 319*
r 250 1019 -61 -83 92 -7 -8 319*

You could iterate through each line, scanning for a second ':' and grab
all the text after that.
