Top Forums UNIX for Beginners Questions & Answers To remove double quotes from specific columns Post 303012178 by Don Cragun on Wednesday 31st of January 2018 08:28:26 AM

As long as there aren't any commas in your quoted fields, the following is a fairly simple way of getting rid of the quotes in specified fields in a text file named file using commas as field separators:
Code:
awk -v list=5,6,9,10,14 '
BEGIN {	OFS = FS = ","
	n = split(list, fields, FS)
}
{	for(i = n; i ; i--)
		gsub(/"/, "", $fields[i])
}
1' file

With your sample input data, this produces the output:
Code:
"event_log_id","event_id","event_name","event_time",insertion_time,event_args,"src_mac","src_name",src_util_id,src_device_type,"src_event_count","src_admin_state","src_ops_state",src_location_util_id,"src_location_type","src_service_pt_util_id","src_service_pt_type","src_addr_line1","src_addr_line2"

which, I assume, is what you wanted.

If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.
