For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
strange chars in expect log_file

Posted by wjlost (wjlost), 16 April 2004
I'm fairly new to tcl and expect. I'm using expect to ssh into another account, and dump the contents of a directory (via "ls -la").

I'm using log_file in order to get the stdout into a file on my machine.
When I open this file later on (vi) I see some strange characters, at the end of every line:
drwx------ 3 root root 4096 Apr 14 06:54 ^[[00m.bashrc^[[00m

this line displays normally this way:
drwx------ 3 root root 4096 Apr 14 06:54 .bashrc

What am I missing here?

Here is the script (very short):
#! /usr/bin/expect --
spawn ssh -l newuser
expect "assword:"
send "newpass\r"
expect "]$ "
send "ls -la\r"
log_file outfile
expect "]$ "

The extra characters are cursor control codes added for your terminal in the ls output.  I suspect that an ls on your target machine shows file names in different colours ... the cursor control sequences setting the colour before the file name and resetting it to black afterwards.
