How to return value from expect script?
Hi there.
There is a shell script:
Code:
#!/bin/bash 
ARGS=`(grep -i $1 old.txt || grep -i $1 new.txt) |awk 'BEGIN {FS=","}{print "\x27" $5 "\x27"}' | tr "\n" " "` 
/usr/bin/expect -- << EXPECTEND 
spawn -noecho myssh myhost.localnet 
log_user 0 
expect root 
log_user 1 
send "/home/one.pl $ARGS\r" 
set val $expect_out(buffer) 
send_user "$val" 
#expect eof 
EXPECTEND

This does not works.
When i commented out line before last, i saw required output, but script executed 10 secs longer, i guess "expect eof" force script to wait for some timeout. However $val is still empty, i just see output of send "/home/one.pl $ARGS\r"
Pls advise how to pass variable from expect to bash without waiting?

getusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

       /bin/bash		  /bin/csh
       /bin/jsh 		  /bin/ksh
       /bin/pfcsh		  /bin/pfksh
       /bin/pfsh		  /bin/sh
       /bin/tcsh		  /bin/zsh
       /sbin/jsh		  /sbin/pfsh
       /sbin/sh 		  /usr/bin/bash
       /usr/bin/csh		  /usr/bin/jsh
       /usr/bin/ksh		  /usr/bin/pfcsh
       /usr/bin/pfksh		  /usr/bin/pfsh
       /usr/bin/sh		  /usr/bin/tcsh
       /usr/bin/zsh		  /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.
