Need to compare two csv files values and write into another csv file
Hi all,
Am new to scripting. So i just need your ideas to help me out. Here goes my requirement.
I have two csv files
1.csv 2.csv
abc,1.24 abc,1
def,2.13 def,1
I need to compare the first column of 1.csv with 2.csv and if matches then need to compare the second coulmnof 1.csv value with 2.csv . if it is more than the 2.csv value then print 1.csv values and second coulmn value of 2.csv and like it goes..And remember the second column of 1.csv is a float value;
the ouput should be in 3.csv
def,2.13,1
my code is goes as folows:
1st way :
for line in `cat 1.csv`
do
samp1=`echo $line|cut -d\
'' -f1`;
samp2=`echo $line|cut -d\
'' -f2`;
for line in `cat
2.csv`
do
samp3=`echo $line|cut -d\
'' -f1`;
samp4=`echo $line|cut -d\
'' -f2`;
if [ $
samp1 -eq $
samp3 ]
then
if [ $
samp2 > $
samp4 ]
then
print "$
samp1",""$
samp2"",""$
samp4">>
3.csv;
break;
fi
fi
done
done
--------------------------------
2nd way
Using Awk i tried :
awk -F"," 'BEGIN { {samp1=$1 ; samp2=$2} {awk 'BEGIN {FS = ","} NR == 1 {samp3=$1 ; samp4=$2} \
{if [ $samp1 -eq $samp3 ]
then
if [ $samp2 -gt $samp4 ]
then
print "$samp1",""$samp2"",""$samp3" >> 3.csv
break
fi
fi}}}'1.csv}'2.csv
Using awk in awk...am not sure..
can anybody help on these two ways...am really worried about this since yesterday...
ManyThanks,
Chinna..

codes less or equal to N, and N- for all characters with codes greather or equal to N). Multiple -i and -x options can be used.
EXAMPLES
Make PDF samples for font.ttf and write them to file samples.pdf:
fntsample -f font.ttf -o samples.pdf
Make PDF samples for font.ttf, compare it with oldfont.ttf and highlight new glyphs. Write output to file samples.pdf:
fntsample -f font.ttf -d oldfont.ttf -o samples.pdf

U+04FF but exclude U+0370-U+03FF:
