use 'se help <action>' to print help for a specific action

actions:
    help (h)
    ssh
    scp
    rsync (rs)
    example (ex)

common-options:
    -H, --Host hosts-file
        line-format: host;user;password;port, do not use it with '-h', no default value.
    -h, --host host;user;password;port
        do not use it with '-H', no default value.
    -u, --user default-user
        optional, defaults to 'root'.
    -p, --password default-password
        optional, defaults to 'x'.
    -P, --port default-port
        optional, defaults to '22'.
    -d, --debug
        optional, prints debug info.
    -k, --keep-order
        optional, keeps sequence of output same as the order of input,
        normally the output of a job will be printed as soon as the job completes.
    -q, --quiet
        optional, suppresses extra information for se, such as se prompt and debug info.
    -s, --select
        optional, select one host which will take effect, the others will be ignored.
    -j, --jobs N
        optional, runs up to N jobs in parallel, 0 means as many as possible,
        defaults to one job per CPU.
    -t, --timeout duration
        optional, time out in seconds, if the command runs for longer than duration
        it will get killed, defaults to 60s.
    --field-sep single-line-field-separator
        optional, defaults to ';'.
    --comment-sep single-line-comment-separator
        optional, defaults to '//'.
    --proxy http_proxy_ip:http_proxy_port
        optional, no default value.

attentions:
    1. '-H' and '-h' can not be used together.
    2. user specified by '-u' can be overridden by USER in 'host;USER;password;port'.
    3. password specified by '-p' can be overridden by PASSWORD in 'host;user;PASSWORD;port'.
    4. port specified by '-P' can be overridden by PORT in 'host;user;password;PORT'.
    5. field-separator is needed if the member in between is not specified,
       for example: host;;password
            in this case, default user will be used, and default user can be overridden by -u.
    6. user defined single-line-field-separator must be specified if password contains ';'.
       for example: '1.2.3.4_@_root_@_my;/passwd_@_22 // this is comment'
       # se ... --field-sep '_@_' ...
    7. user defined single-line-comment-separator must be specified if password contains '//'.
       for example: '1.2.3.4;root;my//passwd;22 !@# this is comment'
       # se ... --comment-sep '!@#' ...

se is an automation tool based on ssh, sshpass, and GNU parallel, it can be used to:
    1. scp|rsync local file|dir(s) to remote, or in reverse.
    2. ssh into host(s) (and execute command|file).

# log into host and execute a command with debug info printed.

# log into host and execute a local file,
# the file will be automatically copied to host in advance.
