我想将文件夹导出到LD_LIBRARY_PATH但只导出一次。我尝试了以下内容来确定文件夹是否已存在
if !(grep --quiet "libBigWig/include" $LD_LIBRARY_PATH)
then
echo "passed"
fi
但它打印声明。这是我的LD_LIBRARY_PATH
/etc:/etc/lib64:/path-to-lib/libBigWig/include

您可以尝试以下方式:
// This is called with the results from from FB.getLoginStatus().
function statusChangeCallback(response) {
// console.log('statusChangeCallback');
//console.log(response);
// The response object is returned with a status field that lets the
// app know the current login status of the person.
// Full docs on the response object can be found in the documentation
// for FB.getLoginStatus().
if (response.status === 'connected') {
// Logged into your app and Facebook.
testAPI();
} else {
// The person is not logged into your app or we are unable to tell.
document.getElementById('status').innerHTML = 'Please log ' +
'into this app.';
}
}
// This function is called when someone finishes with the Login
// Button. See the onlogin handler attached to it in the sample
// code below.
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
}
window.fbAsyncInit = function() {
FB.init({
appId : '1990039811315283',
cookie : true, // enable cookies to allow the server to access
// the session
xfbml : true, // parse social plugins on this page
version : 'v2.8' // use graph api version 2.8
});
// Now that we've initialized the JavaScript SDK, we call
// FB.getLoginStatus(). This function gets the state of the
// person visiting this page and can return one of three states to
// the callback you provide. They can be:
//
// 1. Logged into your app ('connected')
// 2. Logged into Facebook, but not your app ('not_authorized')
// 3. Not logged into Facebook and can't tell if they are logged into
// your app or not.
//
// These three cases are handled in the callback function.
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
};
// Load the SDK asynchronously
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "https://connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
// Here we run a very simple test of the Graph API after login is
// successful. See statusChangeCallback() for when this call is made.
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', {fields: 'name,email'}, function(response) {
console.log('Successful login for: ' + response.name);
/* document.getElementById('status').innerHTML =
'Thanks for logging in, ' + response.name + '!'; */
//console.log(response.email);
//window.location.href = "fb_login.php";
$.ajax({
url:'admin/rest/getEvents',
type:'POST',
//data:JSON.stringify(event_date),
success:function(response){
},
});
});
}
这会有帮助吗?
