autoexpect on docker centos6.6 container cannot work

Docker container pure image: centos6.6 after bash, I install these: yum -y install tar zip unzip expect glibc.i686

Package expect-5.44.1.15-5.el6_4.x86_64 already installed and latest version

and run autoexpect, I always get these error:

[root@179314389a2c bin]# autoexpect
autoexpect started, file is script.exp
no such variable
    (read trace on "env(SHELL)")
    invoked from within
"spawn -noecho $env(SHELL)"
    invoked from within
"if {[llength $argv]>0} {
        eval spawn -noecho $argv
        cmd "spawn $argv"
} else {
        spawn -noecho $env(SHELL)
        cmd "spawn \$env(SHELL)"
}"
    (file "/usr/bin/autoexpect" line 315)
Solution

  • Seems like autoexpect requires the SHELL env var be set but your current running shell (not bash?) does not set it. So try SHELL=bash autoexpect.
