FreeBSD 7.0 manual page repository

FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

      paste - merge corresponding or subsequent lines of files


      paste [-s] [-d list] file ...


      The paste utility concatenates the corresponding lines of the given input
      files, replacing all but the last file’s newline characters with a single
      tab character, and writes the resulting lines to standard output.  If
      end-of-file is reached on an input file while other input files still
      contain data, the file is treated as if it were an endless source of
      empty lines.
      The options are as follows:
      -d list     Use one or more of the provided characters to replace the
                  newline characters instead of the default tab.  The charac‐
                  ters in list are used circularly, i.e., when list is
                  exhausted the first character from list is reused.  This con‐
                  tinues until a line from the last input file (in default
                  operation) or the last line in each file (using the -s
                  option) is displayed, at which time paste begins selecting
                  characters from the beginning of list again.
                  The following special characters can also be used in list:
                  \n    newline character
                  \t    tab character
                  \\    backslash character
                  \0    Empty string (not a null character).
                  Any other character preceded by a backslash is equivalent to
                  the character itself.
      -s          Concatenate all of the lines of each separate input file in
                  command line order.  The newline character of every line
                  except the last line in each input file is replaced with the
                  tab character, unless otherwise specified by the -d option.
      If ‘-’ is specified for one or more of the input files, the standard
      input is used; standard input is read one line at a time, circularly, for
      each instance of ‘-’.
      The paste utility exits 0 on success, and >0 if an error occurs.


      List the files in the current directory in three columns:
            ls | paste - - -
      Combine pairs of lines from a file into single lines:
            paste -s -d ’\t\n’ myfile
      Number the lines in a file, similar to nl(1):
            sed = myfile | paste -s -d ’\t\n’ - -
      Create a colon-separated list of directories named bin, suitable for use
      in the PATH environment variable:
            find / -name bin -type d | paste -s -d : -
      cut(1), lam(1)


      The paste utility is expected to be IEEE Std 1003.2 (“POSIX.2”) compati‐


      A paste command appeared in Version 32V AT&T UNIX.


Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
