Prob in file comparison

[nithink]

hi,.. i know this question is too lengthy... but pls bear with me...
i need to compare 2 files and print the diff in another file... the 2 files look like these....

file 1 file 2

xyz_20021204_0000.txt xyz_20021204_0100.txt
xyz_20021204_0015.txt xyz_20021204_0115.txt
xyz_20021204_0030.txt xyz_20021204_0130.txt
xyz_20021204_0045.txt xyz_20021204_0145.txt
xyz_20021204_0100.txt xyz_20021204_0200.txt
xyz_20021204_0115.txt xyz_20021204_0000.txt
xyz_20021204_0130.txt xyz_20021204_0015.txt
xyz_20021204_0145.txt xyz_20021204_0030.txt
xyz_20021204_0200.txt xyz_20021204_0045.txt
xyz_20021204_0215.txt


for getting the diff, I use sdiff like this...

sdiff -s ./file1 ./file2 | awk -F_ '{if ($1 ~ /xyz/) print $0}' | awk '{print "get " $1}' > ./tmp4

so the output i expect is like this

get xyz_20021204_0215_Q.txt

'coz this is the only diff between the 2 files.. but i'm getting something like this,

get xyz_20021204_0000_Q.txt
get xyz_20021204_0015_Q.txt
get xyz_20021204_0030_Q.txt
get xyz_20021204_0045_Q.txt

Not sure if this will help much, but I noticed that the files side by side were not matched up correctly. Did you run a sort on each file before doing the sdiff?

 

[nithink]

Hi pmcmicha, i didnt sort before sdiff.. i'll try that and let yu know.. thx for ur suggestion..

 

[nithink]

Thx pmcmicha & KenCunningham... it worked... i sorted and then did a "comm"....
