need urgent help for writing shell script

Hello All ,

I am learning Shell Script and i am very fresher . I need help to write one shell script .

We are generating several logs files in our testsuite system . I need to generate fails as per the host ,version and productwise .

The data is stored in different directories and run.log contains fails records with ! sign . I am extracting fails from each directory but cant't accumalte as per the product wise . because product name is stored in Master file product.dat.

The product.dat is Master file contains 2 column
Test Name ProductName
/dialy/test SiCat
/daily/yyyy YRS
/daily/ttttt SiCat
/daily/rttttt SiCat
/daily/wwww PSD
/daily/uuuu YRS



The second file which is generated only contain fails test name for whole system .
The data format is like this
/users/test/krachel/9/run.log
! /daily/wwww
! /daily/test1
! /daily/rrrrr
/users/test/limo/10/run.log
! /daily/wwww
! /daily/test1

The host and version i want to extract form line /users/test/

I have store data like this
Host Version SiCat YRS PSD
limo 10 3 3 5
krache 9 5 7 0

 

Due to the fact of not knowing shell scripting quite good, why do you want to do that with a shell script instead of using sth. like perl, python, php, scripting languages that exists on most *nix installations, that make tasks like this more easy.

 

please give me soultions in Perl . I will be thankful to you .

 

hope i will get help from unix & perl experts . I am waiting fr reply .
Thanks in advance

 

A solution is no help.
But you can find all the things you need in perl here: http://perldoc.perl.org/perl.html

Here you can find things about opening files (http://perldoc.perl.org/functions/open.html), how to cycle to its contents.
Split (http://perldoc.perl.org/functions/split.html), subtring (http://perldoc.perl.org/functions/substr.html) will be helpfull for stringmanipulation, in that case.

It is also helpfull to take a look at perldata (http://perldoc.perl.org/perldata.html) for datatypes you could use storing and cumulating your data read from the files.

when i will start reading and complite the program . Thanks anyway for no help .

 

This is an essential read if you want to do shell scripting: http://www.tldp.org/LDP/abs/html/index.html

 

Um, I'm not sure exactly what you need, but if you are just wanting to extract fields from a file that is easy. For example, if the file is '/users/test/file' and the contents are what you listed above then you would grab the HOST (column 1) and VERSION (column 2) this way:

Code:

wdierkes$ cat /users/test/file | awk {' print "HOST: "$1 "  VERSION:  "$2 '}
HOST: limo  VERSION:  10
HOST: krache  VERSION:  9

That is just a very simple example. Please feel free to clarify if that doesn't answer your question.
