UNIX for Dummies Questions & Answers

Hi ALL.,

THANKS for all your responses.
i tried with the Larry's code. it seems to be working if the DS.txt is in this format
ALBD:xxxxx
FLN:yyyyyyy
WLG:ttttttt

i am getting the desired output i.e
OSC :ALBD: 377
OSC :ALBD :378
OSC: ALBD: 379
FLN :FLN: 140
FLN :FLN :141
WLG :WLG :243
WLG: WLG: 244
WLG :WLG: 245
WLG :WLG :246
MAT: WLG :247


but when i modified the DS.txt as;

ALBD:xxxxx
FLN:yyyyyyy
GIE:ttttttt ( here there is no match)
WLG:ttttttt

then the desired output is getting repeated twice..result.txt is;

OSC :ALBD: 377
OSC :ALBD :378
OSC: ALBD: 379
FLN :FLN: 140
FLN :FLN :141
WLG :WLG :243
WLG: WLG: 244
WLG :WLG: 245
WLG :WLG :246
MAT: WLG :247
OSC :ALBD: 377
OSC :ALBD :378
OSC: ALBD: 379
FLN :FLN: 140
FLN :FLN :141
WLG :WLG :243
WLG: WLG: 244
WLG :WLG: 245
WLG :WLG :246
MAT: WLG :247

the code that i tried is;
for item in `cat $FILE1 | awk -F: '{print $1}'`
do
grep -w $item $FILE2 >>result_file.txt
done

can anyone please give me a suggestion;

thanks

Did you try the above script ? It seems to work fine.

Hi Pavi,

If larry's code is working fine, do the following with the output of larry's code

1) Sort the result file
2) Use Uniq command on the result

sort -u result.txt
uniq result.txt

this will solve your problem until some other solution comes out

gauravgoel,


The grep -w is to search only the value that match.
If you did a grep of arry your result could be marry, larry, harry and arry. But if you use grep -w you will only get arry.
