pwd – print working directory, or what directory am I in?
The user is in the root directory
ls – list directory contents, or what is in this directory?
cd – change directory
man – show the manual page for a command, or what does this command do?
This will show information about the list directory contents command.
touch – create a text file
This would create a text file imaginatively titled ‘textfile’
cat – concatenate – I have only ever used this command to view files that I have created
This would display the contents of the textfile in the command line.
mkdir – create a directory
This would create a folder or directory inside the current folder of marc
cp – copy a file, copies a file from one location to another
cp /Documents/textfile /Documents/marc/textfile
This will copy the text file from the Documents folder and place the copy in the /Documents/Marc folder.
mv – move a file, instead of copying a file, this will mv will move the file. Interestingly this can be used to rename files as well:
mv textfile differentName
Here is a screenshot of all the above commands in use:
rm – remove
This would delete the textfile.
echo – display a line of text
The above command displays and reveals an unfortunate truth.
To use echo to place text inside a text file:
echo Marc is going on a diet > differentname
The following screenshot shows the echo command placing the text that follows to the differentname text file that was created earlier. Take note that I made sure that I was currently in the marc directory that was created earlier.
To add text to that file you must use the >> arrows. If you you use one arrow > you will replace the text.
> create or replace text in file
>> add or append to the text already in the file
