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, flattening them in the process (so giving the following interactive session): % concat a b {c d e} {f {g h}} a b c d e f {g h} it will also concatenate things that are not lists, as can be seen from this session: % concat " a b {c " d " e} f" a b {c d e} f Note also that the concatenation does not remove spaces from the middle of values, as can be seen here: % concat "a b c" { d e f } a b c d e f (i.e., there are three spaces between each of the a, the b and the c).
