I have a script on a Linux machine that connects remotely, via telnet on a windows machine to launch several commands and colect their output. On the Linux machine the output of these commands is redirected in a file.
When I launch the script "manually" from the shell
Code:
./expect.sh > output.txt
The entire output is capted.
When I schedule the script in crontab no output is capted (probably due to the "interact" part of the script).
When I use a wrapper script which launches expect.sh and schedule the wrapper script in crontab output.txt contains only exactly 4.0 Kb and truncates the output of the commands in expect.sh
I'm new to expect and I don;t know how to overcome this. I've red about a full_buffer command but didn;t succeed to get the right syntax to implement it in my script.
Any ideas how to overcome this ?
why do you use interact
try change to "interact" to "expect eof" (or just remove "interact" ) and re-try
regards
ygemici
Already tried exactly this. replaced in my script the "interact" line with "expect eof" and it doesn;t work at all neither directly from shell, neither from crontab.

As you can see, in the cron log appears also the output of the script (I don't know why) and the output is truncated exactly after 4Kb. You can see the last line truncated, that is exactly how the output is redirected in my file.

Does not work in the sense that you launch the script, you expect some output but instead nothing happens. The finishes its execution without displaying any errors nor any output

add -> "sleep 1" after the ( send "pwd\r" ) wait for auth
remove -> last exit (send "exit\r") unneccessary
remove -> (expect "Windows NT Domain:") unneccessary
change to -> "interact" to ( "expect eof" ) tell to our "expect script", we wait to closed the server's connection and expect programm is over. necessary
if its (expect eof) is not in your script, then your output direction may cannot completed because of expect script is closing without completion processes.

Hi Experts,
I found that the same commands(sort, du, df, find, grep etc.) exists in both dir.
What is the difference to use them?
i.e: to use xpg4/bin/grep and usr/bin/grep

Q1. I understand that /usr/local/bin means I can install/uninstall stuff in here and have any chance of messing up my original system files or effecting any other users. I created this directory myself.
But what about the directory I didn't create, namely /Users/m/bin? How is that directory... (1 Reply)
Hi!
All the basic linux commands, ie. echo, find, etc, are located in /bin. I have a couple of programs that have these commands pointed towards /usr/bin, ie, /usr/bin/echo (even though the actual 'echo' command is in /bin). How can I alias or redirect or link the /usr/bin to /bin just for this... (6 Replies)
