我正在编写一个BASH脚本来从Web服务器清除缓存。该脚本旨在从位置参数中获取参数。 “ShellCheck.net”告诉我,我的剧本在功能上是正确的,但是当我测试它时,我会收到错误,我不应该......所以我想我会要求一些人重新审视它。看一看,我将在下面继续描述我的问题:
#!/bin/bash
#
# Verify the user running is root, if not, fail.
if [[ "$UID" -ne "0" ]]; #added-1438279711
then
echo 'Only ROOT may run this script.';
exit 1;
fi
#
# Set the variables
BASE="/path/to/folder/foo/bar/" #added-1438279711
DOMAINOPT="$1" #added 1438451428
PATHOPT="$2" #added 1438451428
#
# Define Functions
function usage() { #added-1438382631
echo -en "Proper Usage:\n\n"
echo -en "\tSpecify the domain to be used\n"
echo -en "\tUsage: \"cleancache.sh abc.com\"\n"
echo -en "\t\tNote: This option will search for files and folders, recursively, within the domain folder, and remove them.\n\n"
echo -en "\tSpecify the URI you'd like to act upon within the domain\n"
echo -en "\tUsage: \"cleancache.sh abc.com /path/to/folder/\"\n"
echo -en "\t\tNote: This option will search for files and folders, recursively,\n\t\twithin the specified path, and remove them. Removing a single file is not currently supported with this script.\n\n"
}
#
# Validate the input
if [[ ! -z "$DOMAINOPT" ]] && [[ "$DOMAINOPT" != "^[A-Za-z0-9-]*[\.][a-z]*$" ]] #added-1438462778
then
clear
echo -en "Please follow the proper format for the DOMAIN option\n\n"
usage
exit 1
elif [[ ! -z "$DOMAINOPT" ]] && [[ "$DOMAINOPT" = "^[A-Za-z0-9-]*[\.][a-z]*$" ]]
then
DOMAINOPT="$DOMAINOPT"
else
clear
echo -en "Please enter a domain!\n\n"
usage
exit 1
fi
if [[ ! -z "$PATHOPT" ]] && [[ "$PATHOPT" != "^[\/][\S]*[\/]$" ]] #added-1438456371
then
clear
echo "Please follow the proper format for the PATH option"
usage
exit 1
elif [[ ! -z "$PATHOPT" ]] && [[ "$PATHOPT" = "^[\/][\S]*[\/]$" ]]
then
PATHOPT="$PATHOPT"
else
echo ""
fi
#
# Doing Stuff
if [[ "$#" -gt "2" ]]
then
echo -en "Too many arguments!\n\n"
usage
exit 1
elif [[ "$#" -eq "2" ]]
then
echo "Purging Cache in \"$BASE$DOMAINOPT$PATHOPT\""
find "$BASE""$DOMAINOPT""$PATHOPT" -type d -exec rm -rf {} \;
find "$BASE""$DOMAINOPT""$PATHOPT" -type f -exec rm -f {} \;
echo "Purging Complete"
exit 0
else
echo "Purging Cache in \"$BASE$DOMAINOPT\""
find "$BASE" -type d -name "$DOMAINOPT" -exec rm -rf {} \;
mkdir -p "$BASE$DOMAINOPT" && chown apache:apache "$BASE$DOMAINOPT" && chmod 755 "$BASE$DOMAINOPT"
echo "Purging Complete!"
echo "Creating \".stat\" file"
echo "" > "$BASE""$DOMAINOPT""/.stat"
if [[ -f "$BASE""$DOMAINOPT""/.stat" ]] #added-1438387045
then
echo "$BASE$DOMAINOPT/.stat file created!"
fi
fi
echo "All Operations Complete, exiting now!"
如果您运行没有任何参数的脚本(请输入域名),一切都会正常响应,如果您尝试在域之前输入路径,它会正常响应...但是当我正确地执行此操作时,当我键入:“cleancache .sh abc.com“,我得到一个错误,就像我没有达到所需的模式(”请遵循DOMAIN选项的正确格式“)......当这是完全写的! ......我不明白我错过了什么,整天都在敲我的头,没有快乐。
请帮助!

使用它来匹配正则表达式:
[[ "$DOMAINOPT" =~ ^[A-Za-z0-9-]*[\.][a-z]*$ ]]
或者这个:
[[ ! "$DOMAINOPT" =~ ^[A-Za-z0-9-]*[\.][a-z]*$ ]]
不要引用正则表达式。
