将变量读取到 ps ax 脚本

Question

您好，我一直在论坛上搜索，但我似乎无法找到正确的答案。我正在尝试创建一个脚本，询问用户他们正在搜索哪个进程，然后 returns 如果进程是运行，则为 1。

这个有效：

#!/bin/bash
SERVICE='httpd'
if ps ax | grep -v grep | grep $SERVICE > /dev/null
then
echo "$SERVICE service running, everything is fine"
else
echo "$SERVICE is not running"
fi

我想将此添加到脚本中：

 echo -e "please enter process name: \c"
 read word

例如：

#!/bin/sh
echo -e "please enter process name: \c"
read input_variable
if ps ax | grep -v grep | grep $varname > /dev/null
then
echo "$SERVICE service running, everything is fine"
else
echo "$SERVICE is not running"
fi

Answer 1

使用pgrep搜索进程：

read process_name
if pgrep "${process_name}" >/dev/null 2>&1 ; then
    "echo ${process_name} found"
else
    "echo ${process_name} not found"
fi
