我试图在Ubuntu 14.04 LTS系统上安装beanstalkd
。似乎没关系,除了以下是给我非零返回状态。一旦发生这种情况,Vagrant会暂停,并且在没有运行的病房之后还有其他脚本可以安装。Bash脚本返回非零状态
我已经试过
grep -q "START=yes"
grep --quiet "START=yes"
grep "START=yes" > /dev/null
非似乎抑制GREP的输出
echo -n "Checking /etc/default/beanstalkd for beanstalkd startup line ... "
if [ -f /etc/default/beanstalkd ]; then
echo -n "START=yes is"
grep "START=yes" /etc/default/beanstalkd > /dev/null
if [ $? = 0 ]; then
echo -n "..already present"
else
echo -n "START=yes" >> /etc/default/beanstalkd
echo -n "..Added to /etc/default/beanstalkd"
fi
fi
echo "Done!"
结果:
==> default: Checking /etc/default/beanstalkd for beanstalkd startup line ...
==> default: START=yes is
The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.
如果GNU,你必须有两个破折号:'--quiet'。 – 2014-10-28 22:25:00
你试过'grep -q'来压制输出吗? – amphetamachine 2014-10-28 22:25:04
@amphetamachine,原来的帖子说是的,他确实尝试过。 – 2014-10-28 22:25:49
