我有一个 shell 脚本,它在第 42 行的 Virtualhost 和 *.结果,唯一回显到控制台的是
<VirtualHost
我想要的是将我的整个字符串回显到控制台。
<VirtualHost *:80>
DocumentRoot /Applications/MAMP/htdocs/web
ServerName web.localhost
<Directory /Applications/MAMP/htdocs/web>
Options Indexes FollowSymLinks MultiViews +Includes
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
这是我的引用脚本:
#!/bin/bash
# This script should be used to automate the web site installation
checkFileForString ()
{
# $1 = file
# $2 = regex
# $3 = text to be added
declare file=$1
declare regex=$2
declare file_content=$( cat "${file}" )
if [[ ! " $file_content " =~ $regex ]]; then
echo "$3" #>> $file
else
replaceStringInFile $file $regex $3
fi
}
replaceStringInFile ()
{
# $1 = file
# $2 = old string
# $3 = new string
sed -i -e 's|${2}|${3}|' $1
}
createFile ()
{
# $1 = file
declare fileToCheck=$1
if [ ! -f $fileToCheck ]; then
touch $fileToCheck
fi
}
# Add vhosts to httpd-vhosts.conf
echo "Adding vhosts to httpd-vhosts.conf"
currentFile="/Applications/MAMP/conf/apache/extra/httpd-vhosts.conf"
currentRegex="<VirtualHost\s[*]:80>\s+DocumentRoot\s/Applications/MAMP/htdocs/web\s+ServerName\sweb.localhost"
newText="<VirtualHost *:80>
DocumentRoot /Applications/MAMP/htdocs/web
ServerName web.localhost
<Directory /Applications/MAMP/htdocs/web>
Options Indexes FollowSymLinks MultiViews +Includes
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
"
checkFileForString $currentFile $currentRegex $newText
最佳答案
需要将变量放在双引号内展开,无需分词和通配符展开。
checkFileForString "$currentFile" "$currentRegex" "$newText"
脚本中的另一个问题是 replaceStringInFile()
函数。变量仅在双引号内扩展,而不是单引号。所以应该是:
sed -i -e "s|${2}|${3}|" "$1"
