File Handling in Julia
We can read an existing file in Julia by using the read() method. It reads the entire content of the file. There are a few helper functions while reading a file; for example, we can use eachline() function to process each line of the file at a time.
We can write in an existing file in Julia by using the write(fileobject, string) method. To write in a file, we need to open the file in write mode. To do so, we have to pass "w" in the mode argument. The most important step while writing a file is to close the file after the computation. If you don't close the file, the contents of the file would be empty.
touch("file.txt")
file = open("file.txt", "r")
data = read(file, String)
file = open("file.txt", "w")
write(file, "Julia")
close(f)
