Parsing Function Arguments. Passing Function Arguments. Returning Values the Classic Way. Returning Values via References.
Let the caller determine how to return the function result and avoid the need of dedicated variables. A function can be called with the CALL command followed by the function label. A single batch file can contain multiple functions defined like this. The label becomes the function name. The following example demonstrates how to pass arguments into a DOS function. The :myDosFunc function is being called multiple times with different arguments.
Subsequently "for" and "me" will be handled as two separate arguments, whereas the third argument "me" is not being used within the function. Download: BatchTutoFunc2. Script Output. When running the batch the first time type a hyphen in order to build the lookup list first. This batch allows string substitution in a text file. It parses each line of a text file for a particular string and replaces it with another string. To replace all occurrences of "Yellow Submarine" in "color. Did you ever pull the paper out of your printer to stop it from printing?
Then surly next thing you did was power cycling the printer to empty the printer buffer and then cancelling the print job from the printer spooler on your PC. The print job sometimes remains a long time in the printer queue before finally disappearing and allowing the next print job to be processed. This is annoying on my box it takes up to 5 minutes. This little batch gets it done. It temporarily stops the spooler service and removes all files from the printer queue. Beware though that all printer jobs will be deleted, not only the ones that got canceled.
This simple menu framework parses itself for batch labels of certain signature and lists them as menu items. The self-parsing feature makes the menu generic. New menu items can be inserted by adding new function blocks without changing the menu infrastructure.
Date and Time functions are useful for: Calculations with date and time values Determine the age of files in days Determine the date difference in days. The example in this section demonstrates how to use the :ftime function to determine the age in days of all files in the temp directory.
Two variables are used tnow - stores the current day in julian days format by calling :jdate tfile - stores the file date in julian days format by calling :ftime. Read more about this behavior in the SET command help bottom half of the help text. If you frequently find yourself calling FTP from the command line, each time having to login and change directory and change FTP modes, until you finally get where you want be in order to do some real work then you may wish to get there with a singe click.
This little batch can connect to your FTP server and logs you in before it gives you the prompt. You can easily add more FTP commands to it, like changing directories or switching to binary mode or whatever you like to be done before taking over control on the FTP prompt.
The FTP connection information is embedded within the batch itself. Optionally a FTP script can be provided as input stream, that way multiple FTP scripts can share the same login information. Example: FtpLogin. First time it retrieves a list of files on the FTP server. The files in the trimmed list are then downloaded during a second connection.
Title Connecting Title Preparing Title Processing Can you comment this? Why do you need the timestamp of ? I like Paul Tomasi's solution proposed by GitaarLAB but I found it has a small bug in that it doesn't work for "08" and "09" days of the month. This is because the leading zero means the system thinks they are invalid octal numbers, and so with this statement:. Invalid number. Numeric constants are either decimal 17 , hexadecimal 0x11 , or octal I found the solution elsewhere on here see dealing with octal variables in batch script , you have to add and then subtract to deal with the leading zero, as per this statement:.

Dear Sir I have an idea, Can you get the date and time string when you click and drag the bottom right clock of the windows taskbar, drag it to any filename box? How would I get the date into a variable for an actual, valuable use? Remove the slashes in the date. Remove the leading space from the time.
This post explains how to get current date and time from command prompt or in a batch file. How to get date and time in a batch file Below is a sample batch script which gets current date and time Datetime. Reply Link. That last part is so helpful and outstanding!
