Top Forums Shell Programming and Scripting I want to find the difference between two files, only for the header (column names) Post 302916595 by gull04 on Thursday 11th of September 2014 03:53:47 AM

Hi Praveen,

The files "a" and "b" should be substituted with your file names, the file "a" is your target file - this file determines the number of declared variables (1 for each column) it also determines the number of "for" loops (1 for each column). The file "b" is the file that has the extra fields/columns.

Please remember to change the delimiter and let me know how you get on.

Regards

Dave

NAME
pr - print file SYNOPSIS
pr [ option ... ] [ file ... ] DESCRIPTION
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name of the file or a specified header, and the page number. With no file arguments, pr prints its standard input. Options apply to all following files but may be reset between files: -n Produce n-column output. +n Begin printing with page n. -b Balance columns on last page, in case of multi-column output. -d Double space. -en Set the tab stops for input text every n spaces. -h Take the next argument as a page header (file by default). -in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces. -f Use formfeeds to separate pages. -ln Take the length of the page to be n lines instead of the default 66. -m Print all files simultaneously, each in one column. -n Number the lines of each file. -on Offset the left margin n character positions. -sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab. -t Do not print the 5-line header or the 5-line trailer normally supplied for each page. -wn For multi-column output, take the width of the page to be n characters instead of the default 72.
