Welcome to my blog, dude! ๐
Today, we're going to take a look at some basic Mac Terminal/Linux commands in my experience.
So, don't roast me friends๐
I'm a n00b at this stuff, so I haven't used shit like cat
, grep
, pbcopy
or pbpaste
yet.
Without further ado, let's get fuckin started!!
1. pwd ๐บ๐
You can use the pwd
command to find out your current location in the filesystem/name of the folder currently open in your terminal window.
The output of pwd
will look something like this:
After executing the pwd
command, the terminal tells us that we're in the folder called Yuri
inside of the folder Users
at root.
2. ls ๐
The ls
command is used to list all the folders/files under the location specified, or if not specified, under the current location.
Here, we're listing all the directories/files inside ~
Also, we can add options/flags to our ls
command, such as:
ls -l
ls -a
ls -l
-l
is the lowercase letter L, and it stands for long. It lists all contents in a long list format.
Here, terminal will output more information about the listed files when we use the -l
option.
This is out the scope of this article, but the long format shows information, such as, permissions, file owner, file size, date, etc.
ls -a
The option a
stands for 'all'. The ls -a
command lists the all of the files inside the current folder/directory, including hidden files.
The photo below shows all of the files inside the ~
folder/directory:
As you saw on the photo above, there's a full-stop (period) at the beginning of certain files. Filenames with a full-stop at the beginning are hidden files.
You can put options/flags together: ls -la
This will produce the same result as doing each option alone, as we saw above.
However, combining two options/flags together outputs both results:
On the photo above, terminal output a long list format with additional information for both regular files and hidden files.
3. mkdir ๐
The mkdir
command stands for 'make directory'. This creates a new folder on your current location (current directory).
Use the mkdir
command with the name of the new file you want to create:
On the photo above, we made a new directory called for_twitter
, then we checked if it was created by using the ls
command.
You can also make multiple directories. If you want to add spaces in directory name, write between quotation marks:
4. cd ๐ โก๏ธ ๐
The cd
command stands for 'change directory'. This allows you to change your current location (current directory) to another directory.
You use the cd
command alongside the other file/directory name you want to change to.
Here, we changed from the ~
directory to the for_twitter
directory:
5. touch ๐
The touch
command creates a new empty file.
You type touch
with the new name of the new file.
Check the terminal below:
There's a couple things going on in this image, let me walk you through it:
On the photo above, we change from the ~
directory to the for_twitter
directory. Then, we created a new HTML file inside. Finally, we verify what's inside the for_twitter
directory with the ls
command.
6. rm, rmdir ๐ฃ
The rm
command stands for 'remove'. rm
removes a FILE from the system completely.
For example, check out the photo below:
On the photo above, we're listing the contents inside the for_twitter
directory, and we see that there's the index.html
file. Then, we remove the index.html
file with the rm
command.
When we check the contents of for_twitter
once again, we see that the index.html
file is gone.
rmdir
The rmdir
command stands for 'remove directory', and you guessed it, It removes an empty directory. It's very similar to the rm
command. You type the name of the directory/folder you want to remove after the rmdir
command and press enter.
rm -rf
Also, you can quickly delete a folder/directory and its contents within with the rm -rf
command.
the r
in -rf
stands for 'recursively' & f
stands for 'force.
So, be VERY careful with this command, as it's forcing deletion. Using this wrongly can cause system damage.
The example below removes dir1
and all of its contents without any warning.
7. cp ยฉ
The cp
command stands for 'copy', and it copies a file from one location to another.
You type cp
with the name of the file you want to copy, then the name of the new file.
If you want to copy a directory/folder, use the -R
option/flag as well.
On the example below, we copy the for_twitter
directory into a new directory/folder called for_twitter_copy
.
8. mv ๐
The mv
command stands for 'move'. The mv
command moves a file to another directory/folder, or (if directory name doesn't exist), it renames the file.
Check this photo below: we moved the index.html
file inside the folder dir2
.
On the photo above, we first listed all the content inside the ~
using the ls
command.
Then, we moved the index.html
file inside the dir2
folder. We do this by using the mv
command followed by the name of the html file we wanted to move, in this case, the index.html
file, followed by the new location, in this case, dir2
.
When we check the contents of dir2
, we can see that we successfully moved the index.html
file inside.
9. man ๐งโโ๏ธ
The man
command stands for 'manual'. It displays all the information about commands that we can run on the terminal. Also, it shows all options/flags you can use.
Below, I typed man ls
, and terminal shows me the manual of the ls
command.
10. sudo ๐ฎ
Finally, the sudo
command allows you to run programs with admin privileges. You'll be required to enter your personal password to execute these commands.
We're done! ๐ฅณ ๐
