I am trying to recover a bash script that has gone "funny".
The nub of it is this.

Three variables are created each to receive the result of an expression.
The results are all character strings:

first=$(an nexpression)
second=$('nother expression)
third=$(yet another expression)

If I echo them indivually they display the desired string

I want to "echo" them as one line with a single space character between them like:

$ echo $first <space> $second <space> $third

I cannot get it to work. :(

or maybe just echo "$first $second $third"

Would be nice to see what the actual error message you were getting is,
but this will probably fix it for you:

$ echo "$first" "$second" "$third"

I must apologise for not framing my question correctly.
What I wanted to do was to output the components that generated the
signature lines below to a file that could be read by sylpheed (news
reader). A desktop icon runs the script following a kernel upgrade.

It works but it is ugly.

You asked for the error messages. I couldn't scroll back to them I'm
sorry.

Thanks for your help everyone. If the Linuxmint web site hadn't been
down, I might have been able to resolve this without troubling everyone.

So what would you rather have than this icon on your desktop?

forums are also back, btw -- but the interaction will be much the same,
in that the people who'd be able to help would want to see the error
messages and/or the script itself.

The single line that did the same thing before it got modified (not by
me) and printed something from sed(?)
