column_cat : catenate files horizontally
Output is sent to stdout, so redirection of output to
a file may be desirable.
Each line of output is the concatination of each current
line from the input files, all on the same line, and
separated by a space. If different separation is desired,
such as a tab, please use the -sep option.
** Note that using '-' or 'stdin' for an input file means
to read from stdin. One such stream is allowed.
Optionos:
-line LINE_NUM : print only line #LINE_NUM (1-based)
e.g. -line 1 (shows top line)
-sep sep_str : use sep_str as separation string
Examples:
column_cat -help
column_cat file_a file_b
column_cat file_a file_b file_c > output_file
column_cat -line 17 file_a file_b file_c > output_file
column_cat -sep : file_a file_b > output_file
column_cat -sep '\t' file_a file_b > output_file
column_cat -sep ' : ' file_a file_b > output_file
cat file_a | column_cat -line 27 stdin
