newbie needs a script

hien — Tue, 17 Dec 2002 08:52:32 GMT

hi guys, pardon me but im still a newbie. ill appreciate any help for this:

i have five log-files, say generation, deletion, filtering,sorting and summarizing. each of this logs contains 3 entries say for generation-log (generation a, b, c...), deletion (deletion a, b, c...) which are variable in length. i wana make a script that could collect the details from each log and integrated the details into file a, file b and file c. so the output files will then be, File a - contains generation a, deletion a, filtering a, sorting a and summarizing a logs.

grep a generation > a.log
grep a deletion >> a.log
grep a filtering >> a.log
grep a sorting >> a.log
grep a summarizing >> a.log

repeat for b, c, etc.

pete, com'on, you can do better than that! :)

grep -e a -e b -e c generation deletion filtering sorting ... > a.log

Good point, Merijn. It's early yet - only one coffee so far.

asdf
asfasdfasdf
asfasdfasdf
==>end of a

hi harry,

actually, its not a log. its an output of a program which we have to filter manually then integrate it to files as reports.

the raw output is usually combination of alpha numeric, with some details that we don't need. usually separted as:

file output 1

======generation a====
asf13asdf
asdf134
asdf12323...
=====end of generation a==

==generation b====
afasdf123123
asdfsadf13
asdfasdf...
==end of generation b===

the other outputs have more orless the same format.
with filtering/removing unwanted details, i have already created a script which mostly uses grep. i have a problem in intergarting them to final data. say, file A should contain output1 A, output2 A, output 3 A...

Hi,

if the files all have the same size, you could use a script like this one (untested):

#! /usr/bin/ksh
>result.txt
let nl=`wc -l file1`
let i=1
while [ $i -le $nl ]
do
a= `head -n $i file1|tail -n 1`
b= `head -n $i file2|tail -n 1`
c= `head -n $i file3|tail -n 1`

echo $a $b $c >> result.txt
let i=$i+1
done

As I don't have access to my platform currently, I couldn't test this cript, but it should not be far from the wished result.
Of course, the head|tail part of the script means that you're reading nl*(nl+1)*2 lines, but that's, after all, still a polynomial algorithm ;-)

Cheers,

FiX

hi,

You could also try a script like this one :

#!/usr/bin/sh
TASK=$1
shift
OUTFILE=$TASK.out
awk '
/=generation '$TASK'=/,/=end of generation '$TASK'=/
/=deletion '$TASK'=/,/=end of deletion '$TASK'=/' $* > $OUTFILE

You could of course use a more complex pattern to delimit begin and end of blocks ... It's really simple because awk use its default action (printing line) for every linesbetween patterns.

Regards.

I forgot to write that you should use this script with the task as first parameter followed by the output files list ...
