Full Discussion: Row bind multiple csv files having different column headers
Top Forums Shell Programming and Scripting Row bind multiple csv files having different column headers Post 302985058 by rbatte1 on Friday 4th of November 2016 08:44:40 AM

I suppose you could:-
Code:
{
  printf "%s,%s\n" "$(head -1 file1)" "$(head -1 file2)"
  sed '2,$ s/$/,,/' file1
  sed '2,$ s/^/,,/' file2
} > output_file

It is rather unwieldy and has no logical control options in it, but I think it fits the brief. There must be more to it than this though,......?

xzdiff

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xzdiff  invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1).  All options specified
       are passed directly to cmp(1) or diff(1).  If only one file is specified, then the files compared are file1 (which must have a suffix of  a
       supported  compression format) and file1 from which the compression format suffix has been stripped.  If two files are specified, then they
       are uncompressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp(1) or diff(1) is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
