Well, it does for the files you gave in your spec in post #1. With declartion.txt
Code:
url;image;id;showcase_id;showcase_name

and feed.txt
Code:
url;image;id;showcase_id;colour;showcase_name
url1;image1;id1;showcase_id1;colour1;showcase_name1
url2;image2;id2;showcase_id2;colour2;showcase_name2
url3;image3;id3;showcase_id3;colour3;showcase_name3
url4;image4;id4;showcase_id4;colour4;showcase_name4

it has stdout as
Code:
url;image;id;showcase_id;showcase_name
url1;image1;id1;showcase_id1;showcase_name1
url2;image2;id2;showcase_id2;showcase_name2
url3;image3;id3;showcase_id3;showcase_name3
url4;image4;id4;showcase_id4;showcase_name4

and mismatch.txt as
Code:
Column 5: colour

Quote:
If the above script is run, it is giving the output as

Column 1: url,dealerid,dealer_name,location,zip,make

in mismatch.txt

As explained above, my need is to find the new columns (in this case two new columns url and make) and remove them from the feed.txt along with it's respective values.

Thanks & Regards
Praveen
As explained above, it does what was specified, and you obviously changed the input file structure.

irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
