It's not really clear what you're asking for, can you elaborate your question a little more?
Sure. Here's an example:

Code:
echo "This is my current directory: " 'pwd'

Then the output would be
Code:
This is my current directory: /Users/codyhazelwood/Dropbox
/Photos/Sample Album

But, I would like to truncate that output so it's only on one line instead of running down onto a second line.

Thanks

line STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: line: XCU5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
