Top Forums Shell Programming and Scripting How to compare data in two flat files and update them? Post 88726 by rajus19 on Tuesday 8th of November 2005 10:09:29 AM

Could you please suggest me how to replace two fields in a flat file which contains more than 40 fields.

If I use sed by searching for the strings there may be a chance that the same string occurs in other fields also.

If I use awk I explicitly metion the rest of the 38 fields.

Please suggest me how to deal with this.

Thanks in advance
Raju
