Top Forums Shell Programming and Scripting Row bind multiple csv files having different column headers Post 302985034 by Don Cragun on Friday 4th of November 2016 03:21:02 AM

Why do some of your output fields have <space> as a replacement for data that is not present (row 2, column C; row 3, column A; and row 3, column B) and other output fields have nothing as a replacement for data that is not present (row 2, column D)?

Why isn't the desired output just:
Code:
A,B,C,D
1,2,3,4

?

Are the column headers between the two files always distinct? If not, how do common column headers affect the desired output?

Are there always just one header line and one data line in each input file? If not, how is the output supposed to be ordered? All lines from File-1 followed by all lines from File2? Alternating lines from File-1 and File-2? Does something different happen if the number of lines in the two files differs?

NAME
psc - prepare sc files SYNOPSIS
psc [-fLkrSPv] [-s cell] [-R n] [-C n] [-n n] [-d c] DESCRIPTION
Psc is used to prepare data for input to the spreadsheet calculator sc(1). It accepts normal ascii data on standard input. Standard out- put is a sc file. With no options, psc starts the spreadsheet in cell A0. Strings are right justified. All data on a line is entered on the same row; new input lines cause the output row number to increment by one. The default delimiters are tab and space. The column for- mats are set to one larger than the number of columns required to hold the largest value in the column. OPTIONS
-f Omit column width calculations. This option is for preparing data to be merged with an existing spreadsheet. If the option is not specified, the column widths calculated for the data read by psc will override those already set in the existing spreadsheet. -L Left justify strings. -k Keep all delimiters. This option causes the output cell to change on each new delimiter encountered in the input stream. The default action is to condense multiple delimiters to one, so that the cell only changes once per input data item. -r Output the data by row first then column. For input consisting of a single column, this option will result in output of one row with multiple columns instead of a single column spreadsheet. -s cell Start the top left corner of the spreadsheet in cell. For example, -s B33 will arrange the output data so that the spreadsheet starts in column B, row 33. -R n Increment by n on each new output row. -C n Increment by n on each new output column. -n n Output n rows before advancing to the next column. This option is used when the input is arranged in a single column and the spreadsheet is to have multiple columns, each of which is to be length n. -d c Use the single character c as the delimiter between input fields. -P Plain numbers only. A field is a number only when there is no imbedded [-+eE]. -S All numbers are strings. -v Print the version of psc SEE ALSO
