击：如何加强输出到一条线？ [英] Bash: How to enforce output to one line?

问题描述

我写了下面的Nagios的检查，检查 / etc / fstab文件的坐骑，并通过使用东风检查他们被正确安装：

I wrote the following Nagios check, which checks /etc/fstab for mounts and by using df checks if they are mounted properly:

#!/bin/bash
# Check mounts based on /etc/fstab
grep="/bin/grep"
awk="/bin/awk"
df="/bin/df"
mounts=$($grep nfs /etc/fstab | $awk '{print $2}')

# Check if mounts exist
for mount in $mounts; do
$df | $grep $mount &>/dev/null
if [ "$?" -eq "0" ]; then
msg="Mount $mount is mounted!"
else
msg="Mount $mount is not mounted!"
fi
echo $msg
done

当我运行检查返回正确的结果：

When I run the check it returns a proper result:

[root@nyproxy5 ~]# ./check_mount.sh 
Mount /proxy_logs is mounted!
Mount /proxy_dump is mounted!
Mount /sync_logs is mounted!
[root@nyproxy5 ~]#

但我想脚本的输出为1行而不是3行，怎么能实现？
我意识到脚本此刻编写方式不允许它，连摩X被安装的消息应该改变，但我有一个很难用逻辑。

But I want the output of the script to be 1 line rather than 3 lines, how can it be achieved? I realize that the way the script is written at the moment doesn't allow it, even the "Mount X is mounted" message should be changed, but I'm having a hard time with the logic.

在此先感谢

推荐答案

修改回声$味精到呼应-n $味精

-n 选项将避免打印换行
