Hello everyone on null byte this is my first tutorial
This Tutorial Is on Useful Lesser Known Commands on Linux
STAT COMMAND:
The stat command displays the status of a file.The information is much more when compared to ls -l. It also includes the absolute path,Number of blocks used by the file,access time, time of modification etc.,,
To use stat:
stat filename
root@localhost:~# stat kali_linux.jpg
File: `kali_linux.jpg'

SHRED COMMAND
The operating system does not completely erase a file when the file is deleted.the file could be recovered by third party forensic tools. But we can use the SHRED command to overwrite a file to make it almost impossible for it to be recovered. The file is overwritten three times, by default,which can be changed by the -n option
root@localhost:~# shred -n 6 NewDocument
WATCH COMMAND
The watch command can be used to repeat a command at fixed intervals.the default interval is 2 second.the interval can be changed with -n option
root@localhost:~# watch -n 2 free
