3. Output of the rm -v file.txt

4. Output of the rmdir -v data

Answer 1

1) cp command is used to copy files from source to destination and follows a syntax like:

cp [options] source destination

Command syntax given in question is incorrect for cp. Following correct syntax:

If we use "cp -v /etc/hosts ~" it will copy hosts file from /etc to your home directory (specified by tilde ~ symbol)

[opc@oel7cloud ~]$ cp -v /etc/host
cp: missing destination file operand after ‘/etc/host’
Try 'cp --help' for more information.
[opc@oel7cloud ~]$
[opc@oel7cloud ~]$ cp -v /etc/hosts ~
‘/etc/hosts’ -> ‘/home/opc/hosts’
[opc@oel7cloud ~]$

2) mv command is used to move/rename files or directory in Linux/Unix. Its syntax is similar to cp command as shown below:

mv [options] source destination

Here we created a file named myfile and then used "mv -v /tmp/myfile ~" which will move myfile from /tmp to your home directory (given by tilde ~ symbol)

[opc@oel7cloud ~]$ touch /tmp/myfile
[opc@oel7cloud ~]$ mv -v /tmp/myfile ~
‘/tmp/myfile’ -> ‘/home/opc/myfile’
[opc@oel7cloud ~]$

3) rm command is used to remove/delete files. Its syntax us given below:

rm [options] filepath

I've created a file named file.txt and then executed "rm -v file.txt" which removed the file as shown in the message.

[opc@oel7cloud ~]$ touch file.txt
[opc@oel7cloud ~]$ rm -v file.txt
removed ‘file.txt’
[opc@oel7cloud ~]$

4) rmdir command is used to remove/delete a directory. Its syntax us given below:

rmdir [options] directorypath

I've created a driectory named data using mkdir command. I then executed "rmdir -v data" which deleted data directory as also shown in the message.

[opc@oel7cloud ~]$ rmdir -v data
rmdir: removing directory, ‘data’
[opc@oel7cloud ~]$

5) " rm -v file.txt" is same as shown above in point 3. Please refer the same.
