Top Forums Shell Programming and Scripting Using sed to remove a column from a CSV Post 302912467 by Corona688 on Friday 8th of August 2014 11:54:03 AM

sed isn't really the right tool for dealing with columns. awk would be the correct tool, it understands columns as columns without weird regex convolutions.

As long as your CSV is actually comma separated -- uses , to separate columns and nowhere else -- this may work:

Code:
awk -F"," -v OFS="," '{ $1="" ; $0=substr($0,2) } 1' inputfile > outputfile

If your CSV isn't actually a CSV, a recursive parser that understands quotes is required and things start getting hard.

BB-CSVINFO.CGI(1)					      General Commands Manual						 BB-CSVINFO.CGI(1)

NAME
bb-csvinfo.cgi - CGI program to show host information from a CSV file SYNOPSIS
bb-csvinfo.cgi DESCRIPTION
bb-csvinfo.cgi is invoked as a CGI script via the bb-csvinfo.sh CGI wrapper. Based on the parameters it receives, it searches a comma- separated file for the matching host, and presents the information found as a table. bb-csvinfo.cgi is passed a QUERY_STRING environment variable with the following parameters: key (string to search for, typically hostname) column (columnnumber to search - default 0) db (name of the CSV database file in $BBHOME/etc/, default hostinfo.csv) delimiter (delimiter character for columns, default semi-colon) CSV files are easily created from e.g. spreadsheets, by exporting them in CSV format. You should have one host per line, with the first line containing the column headings. Despite their name, the default delimiter for CSV files is the semi-colon - if you need a different delimiter, invoke bb-csvinfo.cgi with the "delimiter=<character>" in the query string. Example usage This example shows how you can use the bb-csvinfo CGI. It assumes you have a CSV-formatted file with information about the hosts stored as $BBHOME/etc/hostinfo.csv, and the hostname is in the first column of the file. Use with the bbgen --docurl The --docurl option to bbgen(1) sets up all of the hostnames on your Xymon webpages to act as links to a CGI script. To invoke the bb-csvinfo CGI script, run bbgen with the option --docurl=/cgi-bin/bb-csvinfo.sh?db=hostinfo.csv&key=%s SEE ALSO
