Question

I downloaded some scripts in both python and bash that prompt the user for command line input. Since I run these scripts often, I would like to automatically supply the input to the programs. I prefer not to modify the scripts. Is there a way to do it without modifying the original code?

[UPDATE] thanks to EnabrenTane’s advice, it seems to work pretty well, until I got to a line that read password = getpass.getpass('password: '). It complains the following:

File "/usr/lib/python2.4/getpass.py", line 29, in unix_getpass
old = termios.tcgetattr(fd)     # a copy to save
termios.error: (25, 'Inappropriate ioctl for device')

Any way to get around that?

Due to the password requirement, I ended up using pexpect, a python module that automates user input.
