Unexpected end of file error

[bakar-git]

Scenario:
I am using a webshell. When I do ./PwnKit 'id' or ./PwnKit 'whomai' or ./PwnKit 'who', it shows root (works fine) but when there is a space in command like ./PwnKit 'touch /tmp/some' or ./PwnKit 'ls -lR /u01/app/', it gives following error, I cant use interactive shell because I am accessing the system with jsp reverseshell so I can run one command at time

Error:
/bin/sh: -c: line 0: unexpected EOF while looking for matching `''
/bin/sh: -c: line 1: syntax error: unexpected end of file
