Full Discussion: Get string between quotes separate by commas
Top Forums Shell Programming and Scripting Get string between quotes separate by commas Post 302605371 by gary_w on Wednesday 7th of March 2012 10:14:34 AM

I think you mean separated by semi-colons. There is a comma mixed in there though.
The quick answer:
Code:
nawk -F";" '{gsub(/\"/,"",$4);print $4}' x.csv

But if you want to save the columns into variables for further processing, you could do something like this:

Code:
#!/bin/ksh

INFILE=x.csv

#  Read a semi-colon delimited file, setting variables. Quotes preserve spaces.
while IFS=";" read "name" "age" "sex" "group" "email"
do
  
  print "$group"
 
  # If your shell supports string operations, use this which strips the double-quotes:
  # print "${group//\"/}"

done < $INFILE

exit 0
