File handling isn't always easy, but we got you covered. The hackeroOS terminal offers different commands for editing moving and deleting files.

For all of these commands, you can find help by using the --help flag! So e.g. if you want to know how the cd command works, type cd --help to get an explanation and examples.!

Viewing directories and files

Directories

If you want to list all directories use the ls command. doing so will result in a list of all files and directories like the following:

shrimps@213.71.60.191:# / ls
README.md me cracker.bin downloads www config logs

The entries have different colors for different types:

• blue for normal files
• red for executables
• green for directories

You can also show the directory content as a list by adding the -l flag which results in an output like this:

shrimps@213.71.60.191:# / ls -l
file README.md
dir  me
exec cracker.bin
dir  downloads
dir  www
dir  config
dir  logs

Colors are here the same as describe earlier.

Directories and files can also be hidden by prefixing them with a dot (.). They are hidden by default, but you can make them visible by using the -a

shrimps@213.71.60.191:# / ls -a
README.md me cracker.bin downloads www config logs .hidden

this also works in combination the -l flag as well.

Files

To show the content of a file you can use the cat command or the stat command.

With the cat command you get the content of a normal file:

shrimps@213.71.60.191:# /logs/ cat system
[2019-07-20 14:02:26] localhost has installed software cracker
[2019-07-20 14:10:49] uploaded file README.md to 1.1.1.1

You cannot print the content of an executable that way. for them you have to use the stat command which will show the executables information like filesize or level:

shrimps@213.71.60.191:# / stat cracker.bin
Type      cracker  
Version   1.5      
Size      45MB  

Navigation

To navigate through directories you use the cd command. You need to specify a directory relative to your current directory you want to navigate to. E.g. if you want to navigate from /to /mydirectory/ you type cd mydirectory. Not specifying a path always results in going back to the root (/). To go a directory upwards use two dots cd ... You can also chain these e.g. to go from /dir1/ to /dir2/ you enter cd ../dir2

Create Directories

Creating a directory is really easy. Use mkdir to create a directory.

shrimps@213.71.60.191:# / mkdir foo
shrimps@213.71.60.191:# / ls
README.md me cracker.bin downloads www config logs foo
shrimps@213.71.60.191:# /

Remove files and directories

To remove a file, use rm [filename]

shrimps@213.71.60.191:# / rm bar.txt

To remove a directory you must add the -r flag

shrimps@213.71.60.191:# / rm dir1 -r
