Replace hyphen with empty string in specific column of csv












0















I have a csv file with 30 columns. I need to remove hyphen only from the 30th column.(3rd and 4th column contains hyphen but it should not be removed.)I tried below awk command to achieve it. But it is removing few records and I couldn't find the reason.



awk -f=',' 'gsub= "\-","",$30)' OFS=, input.csv > output.csv


Please suggest a solution to remove hyphens in specific column of csv without removing records.



PFB the sample input:



roll,name,type

01,j-man,re-open

01,i-man,reopen

01,j-man,reopen

01,r-man,re-open


expected output:



roll,name,type

01,j-man,reopen

01,i-man,reopen

01,j-man,reopen

01,r-man,reopen





shell
