Easiest way to strip newline character from input string in pasteboard

Question

Hopefully fairly straightforward, to explain the use case when I run the following command (OS X 10.6):

$ pwd | pbcopy

the pasteboard contains a newline character at the end. I'd like to get rid of it.

Answer 1

pwd | tr -d '\n' | pbcopy

Answer 2

printf $(pwd) | pbcopy

or

echo -n $(pwd) | pbcopy

Note that these should really be quoted in case there are whitespace characters in the directory name. For example:

echo -n "$(pwd)" | pbcopy

Answer 3

I wrote a utility called noeol to solve this problem. It pipes stdin to stdout, but leaves out the trailing newline if there is one. E.g.

pwd | noeol | pbcopy

…I aliased copy to noeol | pbcopy.
