bash echo without newline

Today I ran into an issue with Bash scripting where I had a carriage return piped back from the end of a utility script.

The issue:

# Pipes to the clipboard
echo $some_var | xclip -o -sel clip

This would return a ^@ at the end of my line in Vim. Apparently a carriage return is appended to the end of bash echo commands, using -n removes this.

# Corrected clipboard
echo -n $some_var | xclip -o -sel clip
