Question

I am trying to run the portuguese trained version if MXPOSt which i downloaded from: http://www.nilc.icmc.usp.br/nilc/tools/nilctaggers.html

It seems like I am having a classpath issue but everything seems to check out. At this point I am confused and hoping someone can help. Here is my terminal out below. Thank you guys as always in advance!

username@username-desktop:~$ cd MXPOST/
username@username-desktop:~/MXPOST$ ./mxpost port < text.txt >> out.txt
bash: ./mxpost: /bin/ksh^M: bad interpreter: No such file or directory
username@username-desktop:~/MXPOST$ sudo apt-get install ksh^M
[sudo] password for username:

username@username-desktop:~/MXPOST$ sudo apt-get install ksh

ksh is already the newest version.
The following package was automatically installed and is no longer required:
  libpostproc52:i386
Use 'apt-get autoremove' to remove it.

username@username-desktop:~/MXPOST$ ./mxpost port < text.txt >> out.txt
bash: ./mxpost: /bin/ksh^M: bad interpreter: No such file or directory
username@username-desktop:~/MXPOST$
Was it helpful?

Solution

The script was apparently edited on a Windows machine, which uses CRLF as the line endings, instead of Unix's LF. You need to remove those extraneous CR characters. If you have the dos2unix program, use it, otherwise:

tr -d '\r' < mxpost > mxpost.fixed
mv mxpost.fixed mxpost
