autoexpect & cron
when i run a script made with autoexpect from the command line, it works fine.
when i have cron run the same script it returns spawn /bin/sh sh-3.1$ instead of running anyone have idea what causes this? thanks |
More details?

$ /home/ktemper/ghostbin/autoftp
runs a bash script that sftp's a file to my webhost. it works everytime when i run it from the command line as above. the contents of the bash script are: #!/bin/bash cd /home/ktemper/ghostbin ./autoftp.exp the last line is a script made with the program autoexpect. when i add the bash script to cron with this line: 12 * * * * /home/ktemper/ghostbin/autoftp >> /home/ktemper/autoftpOutputfile it does not sftp to my webhost and the file autoftpOutputfile contains: spawn /bin/sh sh-3.1$ i'm not sure what the output means and also dont understand why it works at the command line and not in cron. shouldnt they be same? |
Two things: can you give the output of "cat /home/ktemper/ghostbin/autoftp.exp". Also, did you try changing the line "./autoftp.exp" to "exec sh autoftp.exp".

changing "./autuftp.exp" "exec sh autoftp.exp" than you for the suggestion.
i also tried opening autoftp.exp in emacs and commenting out the line spawn $env(SHELL) that didnt work, and it wouldnt run at the command line or in cron. ktemper@lofi:~$ cat ghostbin/autoftp.exp #!/usr/bin/expect -f # # This Expect script was generated by autoexpect on Fri Sep 22 23:05:41 2006 # Expect and autoexpect were both written by Don Libes, NIST. # # Note that autoexpect does not guarantee a working script. It # necessarily has to guess about certain things. Two reasons a script # might fail are: # # 1) timing - A surprising number of programs (rn, ksh, zsh, telnet, # etc.) and devices discard or ignore keystrokes that arrive "too # quickly" after prompts. If you find your new script hanging up at # one spot, try adding a short sleep just before the previous send. # Setting "force_conservative" to 1 (see below) makes Expect do this # automatically - pausing briefly before sending each character. This # pacifies every program I know of. The -c flag makes the script do # this in the first place. The -C flag allows you to define a # character to toggle this mode off and on. set force_conservative 0 ;# set to 1 to force conservative mode even if ;# script wasn't run conservatively originally if {$force_conservative} { set send_slow {1 .1} proc send {ignore arg} { sleep .1 exp_send -s -- $arg } } set timeout -1 spawn $env(SHELL) match_max 100000 expect -exact "]0;ktemper@lofi: ~/ghostbinktemper@lofi:~/ghostbin\$ " send -- "sftp tantrumradio@forint.dreamhost.com\r" expect -exact "Password: " send -- "UWneYP#\r" expect -exact "sftp> " send -- "cd tantrumradio.com/playlist" expect -exact "cd tantrumradio.com/playlist" send -- "\r" expect -exact "sftp> " send -- "put playlisy" expect -exact [K" send -- " expect -exact [K" send -- "t.html\r" expect -exact "sftp> " send -- "quit\r" expect -exact "]0;ktemper@lofi: ~/ghostbinktemper@lofi:~/ghostbin\$ " send -- "exit\r" expect eof |
