Question

Eu preciso executar 2 diff cmd no modo ad-hoc em ansible ?? é possível

1] nome do host

2] df -h

# ansible example -s -a "hostname && df -h"

Erro

'''[root@ansi1 ansible]# ansible example -s -a "hostname && df -h"
ansi2.example.com | FAILED | rc=4 >>
Usage: hostname [-v] {hostname|-F file}      set hostname (from file)
       domainname [-v] {nisdomain|-F file}   set NIS domainname (from file)
       hostname [-v] [-d|-f|-s|-a|-i|-y|-A|-I]  display formatted name
       hostname [-v]                         display hostname

       hostname -V|--version|-h|--help       print info and exit

    dnsdomainname=hostname -d, {yp,nis,}domainname=hostname -y

    -s, --short           short host name
    -a, --alias           alias names
    -i, --ip-address      addresses for the hostname
    -I, --all-ip-addresses all addresses for the host
    -f, --fqdn, --long    long host name (FQDN)
    -A, --all-fqdns        all long host names (FQDNs)
    -d, --domain          DNS domain name
    -y, --yp, --nis       NIS/YP domainname
    -F, --file            read hostname or NIS domainname from given file

   This command can read or set the hostname or the NIS domainname. You can
   also read the DNS domain or the FQDN (fully qualified domain name).
   Unless you are using bind or NIS for host lookups you can change the
   FQDN (Fully Qualified Domain Name) and the DNS domain name (which is
   part of the FQDN) in the /etc/hosts file.

Answer 1

Parece que ansible não usa shell para executar seu comando. No entanto, você obviamente usa a sintaxe do shell em seu comando personalizado: && . Então, uma opção para você é dizer diretamente para usar shell:

$ ansible localhost -s -a "bash -c 'hostname && df -h'"
