Question

有一个小的bash脚本，如下所示

Entry present in conf file ($D--- is missing)

it should be      Subsystem       sftp    /usr/libexec/openssh/sftp-server #### ####

但输出如下所示

<resources>
  <!-- Base application theme. -->
  <style  name="AppTheme"parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimaryDark">@color/statusBarColor</item>
    <item name="colorPrimary">@color/toolBarHeaderColor</item>
    <item name="android:windowTranslucentStatus">false</item>
  </style>
  <style name="ThemeToolbar" parent="Theme.AppCompat.Light"> 
    <item name="android:homeAsUpIndicator">@drawable/icon_add_fm</item>
    <item name="android:windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
  </style>
</resources>

有没有办法显示$ D of match box ???

Answer 1

我认为这就是你在这个问题上想要实现的目标。

只需将C更改为您要搜索的字符串即可。

#!/bin/bash

CONF_FILE="/etc/ssh/sshd_config" # the file to search
C="Port 22"                      # The string you want to find
RESULTS=$(grep "$C" $CONF_FILE)  # The grep result
LINES_FOUND=$(echo $RESULTS | wc -l) # How many lines contain C in CONF_FILE

if [ $LINES_FOUND -eq 0 ]; then # File does not contain C
    echo "Entry not present in conf file $CONF_FILE"
    echo ""
    echo -e "it should be \t\t\t$C"
else                            # At least one line matches
    echo "Entry is proper in $CONF_FILE"
fi
