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 spaces 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. For example, the command

concat a b {c d e} {f {g h}}

will return

a b c d e f {g h}

as its result, and

concat " a b {c   " d "  e} f"

will return

a b {c d e} f

as its result.

If no args are supplied, the result is an empty string.

SEE ALSO

append, eval
