Tools run script simultaneous
I have 5 scripts, basicly do the same thing. Use expect and telnet to devices.

First set the variables and the script as follow
Code:
spawn telnet $ipaddr
expect "Username:"
send -- "$usuario\r"
expect "Password:"
send -- "$password\r"
send -- "\r"
send -- "\r"
send -- "copy running-config tftp:\r"
expect "[]?"
send -- "$tftpserver\r"
expect "]?"
send -- "$nameconfig.$gpo.[exec ps -ef | grep -w [pid] | head -1 |  awk {{print $3}}]\r"
expect "#"
send -- "exit\r"
expect eof

When I run the scripts 1 or 2, both run without problems.

Searching to reduce the time, I need run the 5 scripts simultaneously but when configure the /etc/crontab sometimes run 3, sometimes run 4, sometimes run 5.

Do you have a clue?

Could you run it background like : (setting the expected IP values)
(of course the following code may need to be fixed but here is the idea)

Code:
Xpec(){
spawn telnet $1
expect "Username:"
send -- "$usuario\r"
expect "Password:"
send -- "$password\r"
send -- "\r"
send -- "\r"
send -- "copy running-config tftp:\r"
expect "[]?"
send -- "$tftpserver\r"
expect "]?"
send -- "$nameconfig.$gpo.[exec ps -ef | grep -w [pid] | head -1 |  awk {{print $3}}]\r"
expect "#"
send -- "exit\r"
expect eof
}

for i in IP1 IP2 IP3 IP4 IP5
do
Xpec "$i" &
done

What OS are you running?
Show us what lines you have in your crontab
Do your "expect" script requires to be run with a specific user or in a special environment ? (where $usuario as well as $password do come from ?)

The OS is linux FC13

The lines in the crontab is:

Code:
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/home/yuri
MAILTO=root
HOME=/

# For details see man 4 crontabs

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  *  command to be executed
00 22 * * 1-7 yuri /home/yuri/script1
00 22 * * 1-7 yuri /home/yuri/script2
00 22 * * 1-7 yuri /home/yuri/script3
00 22 * * 1-7 yuri /home/yuri/script4
00 22 * * 1-7 yuri /home/yuri/script5

The user for run the script is yuri and not need nothing special in the environment.

Why don't you gather it into one script ?

Code:
 00 22 * * 1-7 launcher


Code:
$ cat launcher
yuri /home/yuri/script1&
yuri /home/yuri/script2&
yuri /home/yuri/script3&
yuri /home/yuri/script4&
yuri /home/yuri/script5&
