bash - 在Bash脚本中将字符串作为命令运行

我有一个Bash脚本，该脚本生成一个字符串以作为命令运行

脚本:

#! /bin/bash

matchdir="/home/joao/robocup/runner_workdir/matches/testmatch/"

teamAComm="`pwd`/a.sh"
teamBComm="`pwd`/b.sh"
include="`pwd`/server_official.conf"
serverbin='/usr/local/bin/rcssserver'

cd $matchdir
illcommando="$serverbin include='$include' server::team_l_start = '${teamAComm}' server::team_r_start = '${teamBComm}' CSVSaver::save='true' CSVSaver::filename = 'out.csv'"

echo "running: $illcommando"
# $illcommando > server-output.log 2> server-error.log
$illcommando

似乎无法将参数正确提供给$serverbin。

脚本输出:

running: /usr/local/bin/rcssserver include='/home/joao/robocup/runner_workdir/server_official.conf' server::team_l_start = '/home/joao/robocup/runner_workdir/a.sh' server::team_r_start = '/home/joao/robocup/runner_workdir/b.sh' CSVSaver::save='true' CSVSaver::filename = 'out.csv'

Usage: /usr/local/bin/rcssserver [[-[-]]namespace::option=value]
                                 [[-[-]][namespace::]help]
                                 [[-[-]]include=file]
Options:
    help
        display generic help

    include=file
        parse the specified configuration file.  Configuration files
        have the same format as the command line options. The
        configuration file specified will be parsed before all
        subsequent options.

    server::help
        display detailed help for the "server" module

    player::help
        display detailed help for the "player" module

    CSVSaver::help
        display detailed help for the "CSVSaver" module

CSVSaver Options:
    CSVSaver::save=<on|off|true|false|1|0|>
        If save is on/true, then the saver will attempt to save the
        results to the database.  Otherwise it will do nothing.

        current value: false

    CSVSaver::filename='<STRING>'
        The file to save the results to.  If this file does not
        exist it will be created.  If the file does exist, the results
        will be appended to the end.

        current value: 'out.csv'

如果我只是粘贴命令/usr/local/bin/rcssserver include='/home/joao/robocup/runner_workdir/server_official.conf' server::team_l_start = '/home/joao/robocup/runner_workdir/a.sh' server::team_r_start = '/home/joao/robocup/runner_workdir/b.sh' CSVSaver::save='true' CSVSaver::filename = 'out.csv'(在“runnning:”之后的输出中)，则可以正常工作。

最佳答案

您可以使用eval执行字符串:

eval $illcommando
