hey ,

my i/p text looks like this,
FILE_TYPE=01|FILE_DESC=Periodic|FILE_SCHDL_TYPE=Daily|FILE_SCHDL=|FILE_SCHDL_TIME=9:00am|RESULTS=B
FILE_TYPE=02|FILE_DESC=NCTO|FILE_SCHDL_TYPE=Daily|FILE_SCHDL=|FILE_SCHDL_TIME=9:00am|RESULTS=M

NOTE Look carefully for the position FILE_TYPE,FILE_DESC etecetra etcetra

this position may varry, e.g. FILE_TYPE is here in 1st postion might be to-morrow in the 3rd or last postion,

So my query is to give the input search name, and it should display the field value, FILE_TYPE and value after = .

Code:

awk -F"|" '/inputvalue/ { print $3 }' filename

what is the corresponding field when you say input search name ?

Give a try,

Code:

#! /usr/bin/perl

$inpFile=$ARGV[0];
$searchStr=$ARGV[1];
open (INP,"<$inpFile") || die "Unable to open INPFILE::$inpFile\n";
while (<INP>) {
        $_ =~ s/\x0a|\x0d//g;
        @inpTag = split(/\|/,$_);
        foreach $value ( @inpTag ) {
                ($key,$val)  = (split ( /=/,$value ));
                if ( $key =~ /\b$searchStr\b/ ) {
                        print "$key= $val\n";
                }
        }
}
close (INP);

hey matrixmadhan, Field is not static, it might be changed across the file.
so according to the i/p search value, i want to fetch the field name and value .

hey lorcan , thanx a lot..can i have this in unix...not thru perl.

lorcan · #5 08-17-2007

Code:

cat your_file | tr "|" "\n" | grep -x "searchField="

or

Code:

tr "|" "\n" < your_file | grep -x "searchField="

code is this ;

cat inputfile |awk -F'|' -v srchname=$1 ' $1 ~ srchname {print $1};
$2 ~ srchname {print $2};$3 ~ srchname {print $3};$4 ~ srchname {print $4};
$5 ~ srchname {print $5};$6 ~ srchname {print $6}'

the first $1 is command line parameter comes from outside the script. so you can use your script this way from command line or call from an another program ;

myscript FILE_TYPE or myscript FILE_DESC etc.

hey fazliturk,

thanx a lot...but if the field is going to change i.e. might be increased from 6 to 7 then , in real time it is not feasible to change the query to add one line $7 ~ srchname {print $7} !!!!!!

So i want irrespective of all the changes to i/p file, that we can think of, it should give us the o/p of the proper search value....but anyway thanx a lot.

lorcan, i tried your one it works fine , with some modification according to my requirement ....But still can we have some more modularized one...using AWK or SED.
