We have requirement here to split file based on colum 3
on 3rd column we have 9 unique values based on this we need split into 2 files one contain 4 another file contain remaining 5 (its based on no of unique values in 3 column if we have 20 unique values we will split into 10 & 10 ) and header should be added on both files
We will count the no of unique values with this cmd
awk -F'|' '{print $3}' inputfile.txt | sort | uniq
half of the count should in one file, remaining in another file
Input file
Header |Name | date
c | 125 | ER de | 126 | ER fr | 127 | ER xe | 128 | ER A | 123 | MR b | 124 | MR c | 125 | XR de | 126 | YR fr | 127 | ZR xe | 128 | NR A | 123 | BR b | 124 | BR c | 125 | CR de | 126 | CR fr | 127 | DR xe | 128 | DR A | 123 | ER b | 124 | ER
Output file 1 c | 125 | ER de | 126 | ER fr | 127 | ER xe | 128 | ER A | 123 | ER b | 124 | ER fr | 127 | DR xe | 128 | DR c | 125 | CR de | 126 | CR A | 123 | BR b | 124 | BR
output file 2
A | 123 | MR b | 124 | MR c | 125 | XR de | 126 | YR fr | 127 | ZR xe | 128 | NR
