Top Forums Shell Programming and Scripting Extracting data from specific rows and columns from multiple csv files Post 302951386 by featheredfrog on Wednesday 5th of August 2015 10:14:58 PM

Confused about ending commas. Some lines end in commas and others don't: this differs between file1 and file2. Are they actually that different or are these typos?

Are there constraints on the solution, must it be bash or can one use awk or perl?

NAME
paste - paste multiple files together SYNOPSIS
paste [-s] [-d list] file... OPTIONS
-d Set delimiter used to separate columns to list. -s Print files sequentially, file k on line k. EXAMPLES
paste file1 file2 # Print file1 in col 1, file2 in col 2 paste -s f1 f2 # Print f1 on line 1 and f2 on line 2 paste -d : file1 file2 # Print the lines separated by a colon DESCRIPTION
Paste concatenates corresponding lines of the given input files and writes them to standard output. The lines of the different files are separated by the delimiters given with the option -s. If no list is given, a tab is substituted for every linefeed, except the last one. If end-of-file is hit on an input file, subsequent lines are empty. Suppose a set of k files each has one word per line. Then the paste output will have k columns, with the contents of file j in column j. If the -s flag is given, then the first file is on line 1, the second file on line 2, etc. In effect, -s turns the output sideways. If a list of delimiters is given, they are used in turn. The C escape sequences , , \, and are used for linefeed, tab, backslash, and the null string, respectively. PASTE(1)
