My_file

Here we're using the open function on a text file called my_file.txt (using a with block to automatically close the file when we're done working with it) and we're calling the write method on the file object we get back to write text to that file:

my_file

To manipulate easily the data, we can consider the contents of the data file, that is a matrix.As an example, we can access the number of lines and columns of a data file named my_file with my_file.contents.dimension.

you are redirecting the contents of ./my_file.txt to the standard input (STDIN) of echo. It doesn't print anything out, though. It happens because echo doesn't read from the standard input, that is, it doesn't give a damn for what is within your STDIN.

In the cell below, we open the file my_file.txt, storing the value returned into a variable named fin (which stands for file input). We then print the type of fin, and see that it has type _io.TextIOWrapper. This object does not contain the actual text from the file, but instead provides a link through which we can access the contents of the file.

We will now explore the readlines() method. In the cell below, we open the file my_files.txt, read its contents using readlines(), and then close the file. We also dispay the results returned by readlines() to confirm that this is a list of strings.

Thanks so much for the response. Yes, I suppose I want to have my cake and eat it too. I prefer working with/developing my code in Rmd files over R scripts (not talking about writing packages or functions here. Talking about analysis projects, e.g., data_01_import.Rmd, data_02_merge.Rmd, data_03_clean.Rmd, analysis_01_descriptive.Rmd, etc.). Once they are developed, however, it would sometimes useful to be able to just execute them as an R script (i.e., source(my_file.Rmd) -- which, of course, doesn't work).

Now we copy my_script.htm and abc.txt as abc_ASD.txt in ASD.What address should we put in fetch(my_file) for it to recognize abc_ASD.txt?fetch44719783 51.6 KB

I have set up a h5serv server using Docker with this image: I launched the server with command:docker run -p 5000:5000 -d -v :/data hdfgroup/h5servwhere is a path to a folder that contains a file my_file.h5.

if exists matches (regex "some_regex") of lines of files "C:\my_file" then "yes" else "no"or, if you can deal with a boolean result instead, the following will give a True/False instead -exists matches (regex "some_regex") of lines of files "C:\my_file"

If I use below command to get data from my_file.txt, it captures all the data and I can get it at consumer console. If my_file.txt is continuosly updating then how can I keep my producer running and keep producing latest data?

/usr/bin/ld: /home/user/projects/my_project/devel/.private/my_project/lib/libmy_file.so: undefined reference to ippicviNorm_L1_32f_C3CMR is the rest of the path. It points to a .so file it fails to build

scp copies files between hosts on a network. To transfer a file (ex. my_file.txt) to the remote secure system via scp, open a terminal on your local computer and navigate to the path where your data file is located.

Assuming your TACC username is jdoe and you are affiliated with UT Austin, a scp transfer that pushes my_file.txt from the current directory of your local computer to the remote secure system would look like this:

sftp is a file transfer program that allows you to interactively navigate between your local file system and the remote secure system. To transfer a file (ex. my_file.txt) to the remote secure system via sftp, open a terminal on your local computer and navigate to the path where your data file is located.

rsyncis a file copying tool that can reduce the amount of data transferred by sending only the differences between the source files on your local system and the existing files in your transfer directory. To transfer a file (ex. my_file.txt) to the remote secure system via rsync, open a terminal on your local computer and navigate to the path where your data file is located.

The above code will serialize the metadata from the dependent variable at indexzero to aJSON file, my_file.csdfe, which includes a link to an external file where thecomponents of the respective dependent variable are serialized as a binaryarray. The binary file is named, my_file_0.dat, where my_file is thefilename from the argument of the save method, and 0 is the index number ofthe dependent variable from the CSDM object.

The ln command creates pseudonyms for files which allows them to beaccessed by different names. These pseudonyms are called links.There are two different forms of the command and two different kinds oflinks that can be created. First, let me explain the two forms. ln [options] exiting_path [new_path] ln [options] exiting_paths directoryIn the first form, a new name is created callednew_path which is a psuedonym forexisting_path. The reason this is called a path isthat it can be a full pathname to a file. That is, it does not have tospecify a file in the current directory.In the second form, the last argument is taken to be a directory nameand all the other arguments are paths to existing files. A link foreach existing file is created in the specified directory with the samefilename as the existing files.Time for a few examples:Create a link named my_file in the current directory to the file/home/bill/his_file: ln /home/bill/his_file my_file As above but the link is created in /home/joe/my_file: ln /home/bill/his_file /home/joe/my_file As above but the link is named his_file and created in the currentdirectory: ln /home/bill/his_file Here is an example of the second form where links to dog, cat and cowfrom the current directory are created in /home/joe: ln dog cat cow /home/joe Everything so far has created what is called a hard link. Allthis means is that the new pseudonym has exactly the same properties asthe original name. In fact, the system makes on distinction betweenthem. For example, you could rename the file pig to chicken with thefollowing command sequence: ln pig chicken rm pigThe first line creates the pseudonym chicken for pig and the seconddeletes pig. The filesystem is smart enough to know that as long as atleast one name points to the file, the file cannot be deleted.All that said, there is a second kind of link called a symbolic linkwhich has quite different properties. That is, rather than pointing tothe file itself, it points to the file name (directory entry). This isthe only kind of link that can be used between filesystems. To create asymbolic link, all works as above except you need to include the -soption.For example, to make a symbolic link called chicken that points to pig,you would say: ln -s pig chickenThe only way you will see that chicken is a symbolic link is by usingthe ls -l command (ls -l chicken). The output of thiscommand will look much like this: lrwxrwxrwx 1 joe users 3 2003-11-18 17:26 chicken -> pigThe first character (l) indicates that this is a link and the chicken-> pig part indicates that chicken is a pointer to pig.Now, if you were to delete the file pig (rm pig) the linknamed chicken would still exist but any attempt to reference it (forexample, cat chicken) would give you a file not found error message.Like most Linux commands, there are lots more options and lots morechoices. If you enter ln --help you will see thecomplete list of options.The first line creates the pseudonym chicken for pig and the seconddeletes pig.
