I think you will find that the variable actually contains what you wanted, if you examine it with env or set. When using it, however, you will need to use double quotes around the variable in order to avoid "flattening" the whitespace.
But that's exactly what I used to get the result I don't want i.e. all lines in one line.
Hi all,
For a intro UNIX course I'm taking, I need to use the command "tr" to display a file on standard output without any newlines (all on one line).
I assume I would start with "cat filename | tr" but don't know what to put after tr.
Any ideas would be lovely!
Thanks. (3 Replies)
