coreutils: paste invocation

 
 8.2 ‘paste’: Merge lines of files
 =================================
 
 ‘paste’ writes to standard output lines consisting of sequentially
 corresponding lines of each given file, separated by a TAB character.
 Standard input is used for a file name of ‘-’ or if no input files are
 given.
 
    Synopsis:
 
      paste [OPTION]... [FILE]...
 
    For example, with:
      $ cat num2
      1
      2
      $ cat let3
      a
      b
      c
 
    Take lines sequentially from each file:
      $ paste num2 let3
      1       a
      2       b
              c
 
    Duplicate lines from a file:
      $ paste num2 let3 num2
      1       a      1
      2       b      2
              c
 
    Intermix lines from stdin:
      $ paste - let3 - < num2
      1       a      2
              b
              c
 
    Join consecutive lines with a space:
      $ seq 4 | paste -d ' ' - -
      1 2
      3 4
 
    The program accepts the following options.  Also see ⇒Common
 options.
 
 ‘-s’
 ‘--serial’
      Paste the lines of one file at a time rather than one line from
      each file.  Using the above example data:
 
           $ paste -s num2 let3
           1       2
           a       b       c
 
 ‘-d DELIM-LIST’
 ‘--delimiters=DELIM-LIST’
      Consecutively use the characters in DELIM-LIST instead of TAB to
      separate merged lines.  When DELIM-LIST is exhausted, start again
      at its beginning.  Using the above example data:
 
           $ paste -d '%_' num2 let3 num2
           1%a_1
           2%b_2
           %c_
 
 ‘-z’
 ‘--zero-terminated’
      Delimit items with a zero byte rather than a newline (ASCII LF).
      I.e., treat input as items separated by ASCII NUL and terminate
      output items with ASCII NUL. This option can be useful in
      conjunction with ‘perl -0’ or ‘find -print0’ and ‘xargs -0’ which
      do the same in order to reliably handle arbitrary file names (even
      those containing blanks or other special characters).
 
    An exit status of zero indicates success, and a nonzero value
 indicates failure.
