Top Forums Shell Programming and Scripting Need help for file filteration script...... Post 302599043 by ctsgnb on Thursday 16th of February 2012 04:44:32 AM

Code:
awk 'NR==FNR{a[$1];next}FNR==1{f=FILENAME "_new"}($1 in a){print $0 > f}' F A B C D E

Your results will be in the files
A_new
B_new
C_new
...

Of course you can specify abolute path.
Code:
awk 'NR==FNR{a[$1];next}FNR==1{f=FILENAME "_new"}($1 in a){print $0 > f}' /home/anubha/ed/F /home/anubha/A /home/anubha/B /home/anubha/C /home/anubha/D /home/anubha/E

The awk code can also easyly be adapted to handle better the naming and the location of the target file i just did a quick shot here.


I haven't tried it so it may require some fix but you can give a try to the following

Code:
cd /home/anubha
awk 'BEGIN{n=split("ABCDEGHIJK",b,"");d="/home/anubha/priya"}
NR==FNR{a[$1];next}
FNR==1{for(i=0;++i<=n/2;) if(b[i]==FILENAME) {t=d "/" b[i+5];break}}($1 in a){print $0 > t}' ./ed/F A B C D E
