Tcl Built-In Commands                                  concat(1T)

NAME
     concat - Join lists together

SYNOPSIS
     concat ?arg arg ...?
_________________________________________________________________


DESCRIPTION
     This command joins  each  of  its  arguments  together  with
     spaces  after trimming leading and trailing white-space from
     each of them.  If all the arguments are lists, this has  the
     same  effect  as  concatenating them into a single list.  It
     permits any number of arguments; if no  args  are  supplied,
     the result is an empty string.

EXAMPLES
     Although concat will concatenate lists (so the command:
          concat a b {c d e} {f {g h}}
     will return "a b c d e f {g h}" as its result), it will also
     concatenate  things  that  are not lists, and hence the com-
     mand:
          concat " a b {c   " d "  e} f"
     will return "a b {c d e} f" as its result.

     Note that the concatenation does not remove spaces from  the
     middle of its arguments, so the command:
          concat "a   b   c" { d e f }
     will return "a   b   c  d  e  f"  (i.e.  with  three  spaces
     between the a, the b and the c).
