remove spaces between strings?

I am working on a "lua console faker" program and it reads what the user types in (local input = read() ) it does not print out the working
directory when you type in cd rom for example so I was wondering if I can like remove the spaces between the two strings.
Example:.
wdir = shell.dir()
print(wdir,">")
but the output is for example:
rom > .
i would like to print this like this:
rom>

Assuming you meant shell.dir (since fs.dir doesn't exist), I cannot reproduce your results.

thx i just fixed it :S
and idk why I typed in the same command and i got this:

That's because in the latest CC versions print() was changed to add spaces between each argument. Just concatenate the strings to remove the space:

print(shell.dir() .. ">")

thank you :)/>
