#!/bin/sh script fails at StringA | tr "[x]" "[y]"
I need to take a string (stringA) check it for spaces and replace any spaces found with an equal (=) sign.
This is not working. There are spaces between each component:
$StringA | tr "[ ]" "[=]"
The error returned is:
test: Specify a parameter with this command
Can you help?

concat
concat(1T) 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 command:
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).
