sending to an xterm
Howdy,
I want to open an xterm, send it a command and have it execute it.
I thought pexpect would do this, but I've been unsuccessful.
term = pexpect.spawn('xterm')
starts an xterm, but
term.sendline('ls')
doesn't seem to do anything.
Suggestions?
Thanks,
Kent

You can't do that. xterm doesn't execute shell commands passed on stdin... It can, however, execute one passed on the command line. Instead of just running xterm, you can run xterm -e 'cmd foo bar' where cmd is the program to run and foo and bar are its arguments. The problem is that as soon as the program exits, xterm will exit also. -- Derek D.

RE: sending to an xterm
since I do not have access to xterm, here is the interactive session for
spawning bash(another session if you will), sending ls command to it, and
retrieving the results.
things to note are:
1. after spawning expect for the prompt, timeout, and eof #which ever happens
first
2. return value is the action that matched
3. if prompt matched, the 'before' has the results
4. even the command 'ls' with '\r\n' will be in the results.
