A new file can be created in 4 different ways: (i) vi, (ii) touch, (iii) cp, and (iv) cat command. You have used touch and cp commands before. In this question, you will use cat command. In part II, you will use the vi text editor. Create a short file using cat command and output redirection operator > like cat > filename. The content of the file must be typed from the keyboard, which is the default standard input (stdin) device. End the input to the file by typing Ctrl d keys at the same time. Copy the file you have created to a new file.

- UNix and bash please write line by line with result and screenshot Create a directory called dir1. Create 10 files in dir1 in whatever way you would like, and fill them with at least a few lines of text. Record how you did this here.Then, write a bsub command line that will submit a job for each file in dir1 to the express squeue that simply “cats” the file. The output file (stdout) for each job should be the <filename>.out. That is, the first job should execute the command: cat file1 and the output should be in file: file1.outCHAPTER 2 EXPLORING THE UNIX/LINUX FILE SYSTEMS AND FILE SECURITY Create a file called samp1e1.View the files present in the current directory in the long listing format.By default the permissions for a file will be rw-rw-r--, change the permissions of the sample1 file to rwxr--r-x, using the rwx notation.View the files present in the current directory in the long listing format.Create a second file called sample2.By default the permissions for a file will be rw-rw-r--, change the permissions of the sample2 file to rwxr-x--x, using 421 method.View the files present in the current directory in the long listing format.STEP BY STEP PLEASE!!
