Question Extracting data from one file, based on another file (splitting)
Dear All,
I have two files but want to extract data from one based on another... can you please help me
file 1
Code:
David
Tom
Ellen

and file 2
Code:
David|0010|testnamez|resultsz
David|0004|testnamex|resultsx
Tom|0010|testnamez|resultsz
Tom|0004|testnamex|resultsx
Ellen|0010|testnamez|resultsz
Ellen|0004|testnamex|resultsx

I want to have separate files based on the names in the file 1 but will have data in file2 and I dont have a problem having the full row
have tried following which will put all in one file
Code:
fgrep -f file1 file2 > result.txt

have tried to create a look and still get the results as I dont know how to make it do line by line
Code:
FILES="*.txt"
for Z in $FILES
do
	name=$(basename $Z) 
	for X in file1
	do	
		fgrep -f $X  file2> ${name}-testing.txt
	done
done

or as other option I think file2 can be divided based on first column then then I can match the lines which my file1
can you please help me please Smilie

Code:
awk -F"|" 'NR==FNR{a[$1]=1;next}$1 in a{print > $1"-testing.txt"}' file1 file2

Try :
Code:
$ awk -F\| 'FNR==NR{A[$1];next}FNR==1{if(f)close(f);split(FILENAME,F,".");f=F[1]"-testing.txt"}($1 in A){print $0>f}' file1 *.txt

Thanks for quick replys but none seems to work ... no files get created by them
P.S. the file1 does not have any separators (e.g. "|")

How did you try what's your real input ? whats expected output ? whether you want to create file based on names in column1 of file1 as bartus11 did it or wildcard input you are using that is basename with new suffix ? Sorry I am confused.

i want the outputs to look like
David.txt
Code:
David|0010|testnamez|resultsz
David|0004|testnamex|resultsx

Tom.txt
Code:
Tom|0010|testnamez|resultsz
Tom|0004|testnamex|resultsx

Ellen.txt
Code:
Ellen|0010|testnamez|resultsz
Ellen|0004|testnamex|resultsx

I tried but as one liner as well as in the loop
note: I am using Cygwin

Bartus11's approach should work, but I suspect about your loop, please post your code with loop you tried.
