Ritchie and Ken Thompson. Linux is Unix-Like operating system. There are several Linux distros available most are open-source and free to download and use such as Ubuntu, Debian, Fedora, Kali, Mint, Gentoo, Arch and much more. Basic unix commands: 1. As shown above on my system i am the only user currently logged in. You can understand this a double clicking a folder and then you do some stuff in that folder. As there are many modes in Unix that can be used to manipulate files in the Unix environment. You will need them even if you get advance the Unix. If you want to master them just keep on practicing them. Also it is not possible to cover all the Unix commands because they are so much in number. You can find more, just google it and you will find most of them.

To create a date from an array at UTC, use moment. Because this mirrors the native Date parameters, months, hours, minutes, seconds, and milliseconds are all zero indexed. Years and days of the month are 1 indexed. If the date represented by the array does not exist, moment isValid will return false. All moments are mutable. If you want a clone of a moment, you can do so implicitly or explicitly.

If you want to parse or display a moment in UTC, you can use moment. It is important to note that though the displays differ above, they are both the same moment in time. Any moment created with moment. To switch from UTC to local time, you can use moment utc or moment local.

Moment's string parsing functions like moment string and moment. In contrast, moment. You can check whether the Moment considers the date invalid using moment isValid. You can check the metrics used by isValid using moment parsingFlags , which returns an object. In addition to the above, As of 2. Additionally, if the Moment is parsed in strict mode, these flags must be empty for the Moment to be valid:. Moment's concept of validity became more strict and consistent between 2.

Validity is determined on moment creation. A modified moment i. In case of multiple wrong units the first one is returned because days validity may depend on month, for example. After a moment object is created, all of the inputs can be accessed with creationData method:. You can create a moment object specifying only some of the units, and the rest will be defaulted to the current day, month or year, or 0 for hours, minutes, seconds and milliseconds.

You may be familiar with this pattern from its use in jQuery. Calling these methods without parameters acts as a getter, and calling them with a parameter acts as a setter. For convenience, both singular and plural method names exist as of version 2. From 2. Before 2. Moment date is for the date of the month, and Moment day is for the day of the week.

Use moment. If the value given is from 0 to 6, the resulting date will be within the current Sunday-to-Saturday week. As of 2. This is parsed in the moment's current locale.

If the locale assigns Monday as the first day of the week, moment. If Sunday is the first day of the week, moment. Because different locales define week of year numbering differently, Moment. The week of the year varies depending on which day is the first day of the week Sunday, Monday, etc , and which week is the first week of the year. For example, in the United States, Sunday is the first day of the week. The week with January 1st in it is the first week of the year.

In France, Monday is the first day of the week, and the week with January 4th is the first week of the year. The output of moment week will depend on the locale for that moment.

Before version 2. Because the first day of the first week does not always fall on the first day of the year, sometimes the week-year will differ from the month year. For example, in the US, the week that contains Jan 1 is always the first week. In the US, weeks also start on Sunday. If Jan 1 was a Monday, Dec 31 would belong to the same week as Jan 1, and thus the same week-year as Jan 1. Dec 30 would have a different week-year than Dec Gets the number of weeks in the current moment's year, according to ISO weeks.

Units are case insensitive, and support plural and short forms: Once you have a Moment , you may want to manipulate it in some way. There are a number of methods to help with this. This allows you to do crazy things like the following. It should be noted that moments are mutable. Calling any of the manipulation methods will change the original moment. If you want to create a copy and manipulate it, you should use moment clone before manipulating the moment.

More info on cloning. This is a pretty robust function for adding time to an existing moment. To add time, pass the key of what time you want to add, and the amount you want to add. If you want to add multiple different keys at the same time, you can pass them in as an object literal. If the day of the month on the original date is greater than the number of days in the final month, the day of the month will change to the last day in the final month. There are also special considerations to keep in mind when adding time that crosses over daylight saving time.

If you are adding years, months, weeks, or days, the original hour will always match the added hour. If you are adding hours, minutes, seconds, or milliseconds, the assumption is that you want precision to the hour, and will result in a different hour. It has been deprecated in favor of moment add Number, String. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer. This is exactly the same as moment add , only instead of adding time, it subtracts time.

It has been deprecated in favor of moment subtract Number, String.

Note that in order to make the operations moment. This is the same as moment startOf , only instead of setting to the start of a unit of time, it sets to the end of a unit of time. This function has been deprecated in 2. Consider moment. Limits the moment to a maximum of another moment value. Sometimes, server clocks are not quite in sync with client clocks. This ends up displaying humanized strings such as "in a few seconds" rather than "a few seconds ago".

You can prevent that with moment max:. Limits the moment to a minimum of another moment value. Sets a flag on the original moment to use local time to display a moment instead of the original moment's time. Sets a flag on the original moment to use UTC to display a moment instead of the original moment's time.

Unlike moment. Setting the UTC offset by supplying minutes. The offset is set on the moment object that utcOffset is called on. If you are wanting to set the offset globally, try using moment-timezone. Note that once you set an offset, it's fixed and won't change on its own i.

If the input is less than 16 and greater than , it will interpret your input as hours instead. The utcOffset function has an optional second parameter which accepts a boolean value indicating whether to keep the existing time of day. Passing false the default will keep the same instant in Universal Time, but the local time will change.

Passing true will keep the same local time, but at the expense of choosing a different point in Universal Time. One use of this feature is if you want to construct a moment with a specific time zone offset using only numeric input values:. This is the most robust display option. It takes a string of tokens and replaces them with their corresponding values. They display 3 significant digits and the rest is filled with zeros.

Because preferred formatting differs based on locale, there are a few tokens that can be used to format a moment based on its locale. There are upper and lower case variations on the same formats. The lowercase version is intended to be the shortened version of its uppercase counterpart.

LTS was added in 2. While these date formats are very similar to LDML date formats, there are a few minor differences regarding day of month, day of year, and day of week. For a breakdown of a few different date formatting tokens across different locales, see this chart of date formatting tokens.

To compare Moment. Calling moment format without a format will default to moment. Out of the box, moment. In such cases, it may be useful to set moment.

Changing the value of moment. A common way of displaying time is handled by moment fromNow. This is sometimes called timeago or relative time. The base strings are customized by the current locale.

Time is rounded to the nearest second. The breakdown of which string is displayed for each length of time is outlined in the table below. The ss key was added in 2. It is an optional threshold. Until the ss threshold is set, it defaults to the value of the s threshold minus 1 so, invisible to the user. You may want to display a moment in relation to a time other than now.

In that case, you can use moment from. The first parameter is anything you can pass to moment or an actual Moment. Like moment fromNow , passing true as the second parameter returns value without the suffix. This is useful wherever you need to have a human readable length of time.

A common way of displaying time is handled by moment toNow. This is similar to moment. In that case, you can use moment to. Like moment toNow , passing true as the second parameter returns value without the suffix. Calendar time displays time relative to a given referenceTime defaults to now , but does so slightly differently than moment fromNow. To get the difference in milliseconds, use moment diff like you would use moment from. To get the difference in another unit of measurement, pass that measurement as the second argument.

To get the duration of a difference between two moments, you can pass diff as an argument into moment duration. See the docs on moment duration for more info. The supported measurements are years , months , weeks , days , hours , minutes , and seconds. For ease of development, the singular forms are supported as of 2.

Units of measurement other than milliseconds are available in version 1.

By default, moment diff will truncate the result to zero decimal places, returning an integer. If you want a floating point number, pass true as the third argument. If the moment is earlier than the moment you are passing to moment. It is optimized to ensure that two months with the same date are always a whole number apart. See more discussion on the month and year diffs here. This change to month and year diffs was made in 2. To get a Unix timestamp the number of seconds since the epoch from a Moment , use moment unix.

This will return a copy of the Date that the moment uses, so any changes to that Date will not cause moment to change. If you want to change the moment Date , see moment manipulate or moment set.

Note that. This is done to provide consistency with the specification for native JavaScript Date. This returns an object containing year, month, day-of-month, hour, minute, seconds, milliseconds. Returns a machine readable string, that can be evaluated to produce the same moment. Because of the name its also used in node interactive shell to display objects. This function is mostly intended for debugging, not all cases are handled precisely. Check if a moment is before another moment. The first argument will be parsed as a moment, if not already so.

If you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter. As the second parameter determines the precision, and not just a single value to check, using day will check for year, month and day.

Like moment isAfter and moment isSame , any of the units of time that are supported for moment startOf are supported for moment isBefore.

If the code runs fast the initial created moment would be the same as the one created in isBefore to perform the check, so the result would be false. But if the code runs slower it's possible that the moment created in isBefore is measurably after the one created in moment , so the call would return true.

Check if a moment is the same as another moment. If you want to limit the granularity to a unit other than milliseconds, pass it as the second parameter. When including a second parameter, it will match all units equal or larger. Passing in month will check month and year. Passing in day will check day , month , and year. Besides using the find command to locate files, you can also use it to execute other Linux commands grep, mv, rm, etc.

The remaining sections on this page describe more fully the commands just shown. If it finds the file, it prints the location to the screen. If you don't care about that, just leave the -type f option off your command. The filename can end with any other combination of characters.

It will match filenames such as Chapter, Chapter1, Chapter1. Just replace the -f option with a -d option. For instance, to find all directories named build under the current directory, use this command: find. This next command shows how to find all files beneath the current directory that end with the extension.
