We can read and write to files with the help of file commands in c programming.There are so many commands related to file for read,write,append,delete etc.
read: moving data from file to memory write: moving data from memory to file
Ubuntu supports a large number of file systems, including ext2 (read/write), ext3 (read/write), ext4 (read/write), ReiserFS (read/write), JFS (read/write), XFS (read/write), FAT (read/write), and NTFS (read, additional software available for writing). With the exception of NTFS, it can also boot off of the above file systems.
you can use inputstream for reading the file java.io.fileinputstream and write the file using outputstream..
I suggest something like this:* Open file1 and file2 * Create a temporary output file, for writing * Read a line from file1, write it into the output file * Read a line from file2, write it into the output file * Repeat the previous two steps, while you are not at end-of-file in either of the two files * At this point, if you are NOT at end-of-file in file1, read the remaining lines of file1, and write them to the output (you can write a loop for this). * Similarly, if you are NOT at end-of-file in file2, read and write the remaining file. * Close file1, file2, and the output file. * Copy the temporary output file back to file1 * Erase the temporary output file
fopen, fread, fwrite, fclose
these are not commands, but functions. Some of them are: open, close, read, write; fopen, fclose, fread, fwrite, fgets, fputs, fprintf, fscanf, fgetc, fputc.
Please refine your question, it is not precise enough to get a clear understanding of what you are asking.

Write to the file, append to the file, and read or change its attributes.
