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..

mdbfontset
mdbFontset(5) The m17n Library mdbFontset(5)
NAME
mdbFontset - Fontset
DESCRIPTION
The m17n library loads a fontset definition from the m17n database by the tags <fontset, FONTSET-NAME>. The plist format of the data is as
follows:
FONTSET ::= PER-SCRIPT * PER-CHARSET * FALLBACK *
PER-SCRIPT ::= '(' SCRIPT PER-LANGUAGE + ')'
PER-LANGUAGE ::= '(' LANGUAGE FONT-SPEC-ELEMENT + ')'
PER-CHARSET ::= '(' CHARSET FONT-SPEC-ELEMENT + ')'
FALLBACK ::= FONT-SPEC-ELEMENT
FONT-SPEC-ELEMENT ::= '(' FONT-SPEC [ FLT-NAME ] ')'
FONT-SPEC ::=
'(' [ FOUNDRY FAMILY
[ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
REGISTRY
[ OTF-SPEC ] [ LANG-SPEC ] ')'
SCRIPT is a symbol of script name (e.g. latin, han) or nil. LANGUAGE is a two-letter symbol of language name code defined by ISO 639 (e.g.
ja, zh) or nil.
FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
See m17nFont for the meaning of each property.
OTF-SPEC is a symbol specifyng the required OTF features. The symbol name has the following syntax.
OTF-SPEC-NAME ::= ':otf=' SCRIPT LANGSYS ? GSUB-FEATURES ? GPOS-FEATURES ?
SCRIPT ::= SYMBOL
LANGSYS ::= '/' SYMBOL
GSUB-FEATURES ::= '=' FEATURE-LIST ?
GPOS-FEATURES ::= '+' FEATURE-LIST ?
FEATURE-LIST ::= '~' ? FEATURE ( ',' '~' ? FEATURE ',' )
Here, FEATURE is a four-letter Open Type feature.
LANG-SPEC is a symbol specifying the required language support. The symbol name has the following syntax.
LANG-SPEC-NAME ::= ':lang=' LANG
Here, LANG is a two or three-letter ISO-639 language code.
FLT-NAME is a name of Font Layout Table (Font Layout Table).
EXAMPLE
This is an example of PER_SCRIPT.
(han
(ja
((jisx0208.1983-0)))
(zh
((gb2312.1980-0)))
(nil
((big5-0))))
It instructs the font selector to use a font of registry 'jisx0208.1983-0' for a 'han' character (i.e. a character whose Mscript property
is 'han') if the character has Mlanguage text property 'ja' in an M-text and the character is in the repertories of such fonts. Otherwise,
try a font of registry 'gb2312.1980-0' or 'big5-0'. If that 'han' character does not have Mlanguage text property, try all three fonts.
See the function mdraw_text() for the detail of how a font is selected.
