Split a single file into multiple files based on a value.
Hi All,

I have the sales_data.csv file in the directory as below.

Code:
SDDCCR;  SOM   ; MD6546474777   ;05-JAN-16
ABC   ;  KIRAN ; CB789          ;04-JAN-16
ABC   ;  RAMANA; KS566767477747 ;06-JAN-16
ABC   ;  KAMESH; A33535335      ;04-JAN-16
SDDCCR;  DINESH; GD6674474747   ;08-JAN-16
SDDCCR;  SUJAN ; SA6666464664646;05-JAN-16
XYZ  ;   AMAR  ; AB123456       ;04-JAN-16
XYZ  ;   RAJ   ; CS78890        ;04-JAN-16
XYZ  ;   GANE  ; MD6546474777   ;08-JAN-16
XXX  ;   MANO  ; MD6546474777   ;04-JAN-16

I want to split the file as below based on last column value.

sales_data04-JAN-16.csv
Code:
ABC   ;  KIRAN ; CB789          ;
ABC   ;  KAMESH; A33535335      ;
XYZ  ;   AMAR  ; AB123456       ;
XYZ  ;   RAJ   ; CS78890        ;
XXX  ;   MANO  ; MD6546474777   ;

sales_data05-JAN-16.csv
Code:
SDDCCR;  SOM   ; MD6546474777   ;
SDDCCR;  SUJAN ; SA6666464664646;

sales_data06-JAN-16.csv
Code:
ABC   ;  RAMANA; KS566767477747 ;

sales_data08-JAN-16.csv
Code:
SDDCCR;  DINESH; GD6674474747   ;
XYZ  ;   GANE  ; MD6546474777   ;

I have tried the following script but its working.

Code:
#!/bin/ksh 
file_name=sales_data.csv
file_format=$4
awk ' NR==1 {HD = $1 OFS $2  OFS $3; next; next} {FN = DIR"/sales_data"  file_out 
                 if (!(Se[FN]++)) print HD > FN
                 print  $1, $2, $3 >  FN}' FS=' *; *' OFS=";" DIR="$SAL_DIR" file_out="$file_format" $SAL_DIR/$file_name
if [ $? -ne 0 ]
then
  echo "report generation failed"
  fin_anormale $0
fi

#End of File

ASAP is a highly deprecated term in these fora.

How about
Code:
awk -F";" '{print > "sales_data" $4 ".csv"}' file

How about
Code:
awk -F";" '{print > "sales_data" $4 ".csv"}' file

$4 should not be included:

Code:
awk -F\; '{f= "sales_data" $4 ".csv"; $4=""; print > f}' OFS=\; file

Or
Code:
awk -F";" '{print $1";"$2";"$3 > "sales_data" $4 ".csv"}' file

Hi All,

Thanks a lot to all.

I forgot to mention one thing the sales_data.csv is having heading.
Code:
SCID     NAME     SCODE           CREATE_DATE
SDDCCR;  SOM   ; MD6546474777   ;05-JAN-16
ABC   ;  KIRAN ; CB789          ;04-JAN-16
ABC   ;  RAMANA; KS566767477747 ;06-JAN-16
ABC   ;  KAMESH; A33535335      ;04-JAN-16
SDDCCR;  DINESH; GD6674474747   ;08-JAN-16
SDDCCR;  SUJAN ; SA6666464664646;05-JAN-16
XYZ  ;   AMAR  ; AB123456       ;04-JAN-16
XYZ  ;   RAJ   ; CS78890        ;04-JAN-16
XYZ  ;   GANE  ; MD6546474777   ;08-JAN-16
XXX  ;   MANO  ; MD6546474777   ;04-JAN-16

I need heading for every split file as below.

sales_data04-JAN-16.csv

Code:
SCID     NAME     SCODE  
ABC   ;  KIRAN ; CB789          ;
ABC   ;  KAMESH; A33535335      ;
XYZ  ;   AMAR  ; AB123456       ;
XYZ  ;   RAJ   ; CS78890        ;
XXX  ;   MANO  ; MD6546474777   ;

sales_data05-JAN-16.csv

Code:
SCID     NAME     SCODE        
SDDCCR;  SOM   ; MD6546474777   ;
SDDCCR;  SUJAN ; SA6666464664646;

sales_data06-JAN-16.csv

Code:
SCID     NAME     SCODE    
ABC   ;  RAMANA; KS566767477747 ;

sales_data08-JAN-16.csv
Code:
SCID     NAME     SCODE     
SDDCCR;  DINESH; GD6674474747   ;
XYZ  ;   GANE  ; MD6546474777   ;

My below script is working fine apart from ganerating one more saparate file for heading
and not giving heading in all split files.
Code:
#!/bin/ksh 
file_name=sales_data.csv
awk ' NR==4 {HD = $1 OFS $2  OFS $3; next; next} {FN = DIR"/sales_data_"$4".csv"  file_out 
                 if (!(Se[FN]++)) print HD > FN
                 print  $1, $2, $3 >  FN}' FS=' *; *' OFS=";" DIR="$SAL_DIR" file_out $SAL_DIR/$file_name
if [ $? -ne 0 ]
then
  echo "report generation failed"
  fin_anormale $0
fi

Please help me.

Thanks.
