I’m trying for a while to work this out with no success so far
I have a command output that I need to chew to make it suitable for further processing
The text I have is:
1/2 [3] (27/03/2012 19:32:54) word word word word 4/5
What I need is to extract only the numbers 1/2 [3] 4/5 so it will look:
1 2 3 4 5
So, basically I was trying to exclude all characters that are not digits, like “/”, “[“, “]”, etc.
I tried awk with FS, tried using regexp, but none of my tries were successful.
I would then add something to it like
first:1 second:2 third:3 …. etc
Please take in mind I’m talking about a file that contains a lot if lines with the same structure, but I already though about using awk to sum every column with
awk '{sum1+=$1 ; sum2+=$2 ;......etc} END {print "first:"sum1 " second:"sum2.....etc}'
But first I will need to extract only the relevant numbers,
The date that is in between “( )” can be omitted completely but they are numbers too, so filtering merely by digits won’t be enough as it will match them too
Hope you can help me out
Thanks in advance!
This:
sed -r 's/[(][^)]*[)]/ /g; s/[^0-9]+/ /g'should work. It makes two passes, removing parenthesized expressions first and then replacing all runs of non-digits with single spaces.
