bash - Exporting data from expect script -

-

so i've written short expect script logs apc power distribution unit interface via telnet , polls current ampage.

    #!/usr/bin/expect     set ip "192.168.0.1"     set username "myusername"     set password "mypassword"     spawn "/bin/bash"     send "telnet $ip\r"     expect "*user name*"     send "$username\r"     expect "*password*"     send "$password\r"     expect "*apc*"     send -- "phreading current\r"     expect "*success*"     send  "quit\r"     expect eof

the script job , see amps on screen, displayed this:

    apc>phreading current     e000: success     1: 7.5     apc>quit

what need 'export' 7.5 figure, either text file or pass bash script variable.

any ideas on how can this?

thank you!

expect extension of tcl, have access of tcl's constructs.

if have expect script write directly file.

see section "writing file" here: http://wiki.tcl.tk/367. has simple example that. in case, want open file append (a) instead of write (w).

open command documentation at: http://www.tcl.tk/man/tcl8.6/tclcmd/open.htm

let me know how works you.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
