Prijavi se na sistem.
V domači mapi najdeš imenik Mapa z 20 datotekami.
  - Preimenuj vse datoteke tako, da zamenjaš minuse s podčrtaji
  - Napiši čim krajši ukaz, ki vse datoteke iz /home/user/mapa/mojimenik premakne v /home/user/novi
  - Napiši ukaz, ki s pomočjo ukaza grep v datoteko "mama.txt" izpiše vse navade (ne skrite) datoteke v trenutnem imeniku, ki vsebujejo niz "mama", v datoteko "napake.txt" pa izpiše vse morebitne napake (npr. to, da so nekateri objekti v trenutnem imeniku dejansko imeniki ali napačne simbolične povezave)
  - Napiši ukaz, ki bo 5s sledil vsebini /var/log/syslog. V primeru, da se v syslogu pojavi niz "zmeda", naj program izpiše "imam ga". Poleg tega naj program med sledenjem syslog-u odšteva od 5 do 1 (vsako sekundo naj se izpiše naslednja številka.
  - Nastavi okoljsko spremenljivko TEST, da bo imela isto vrednost kot okoljska spremenljivka USER + število okoljskih spremenljivk, ki v imenu ali vrednosti ne vsebujejo besede TEST. Primer: polz37
  - S pomočjo programa cURL shrani vsebino spletne strani www.google.com  v datoteko  z imenom website.txt
  - V imeniku "Mapa" najdeš datoteko count.txt. Preštej število vrstic v njej in rezultat zapiši v novo datoteko lines.txt
  - Namesti paket "cowsay" in ga preizkusi :)
  - Napiši najkrajši ukaz, ki s pomočjo Pythona zažene preprost (integriran) HTTP strežnik kateri streže datoteke iz imenika iz katerega je bil pognan na vratih 8000

Log into the system.
In your home folder you will find a directory called Folder containing 20 files.
  - Rename all files replacing minus sign with the underscore
  - Specify the shortest command for copying all the files located in /home/user/Folder into the folder /home/user/new
  - Specify the shortest command, which will, using the grep command, 
write all normal (not hidden) files containing a string "mama" located 
in working directory (pwd) into file "mama.txt" while writing errors such as files in current directory being folders or symbolic links in the file called "Errors.txt"
  - Specify a command, which will track the contents of /var/log/syslog 
for 5s. In case it finds the entry "confusion" in syslog, print "got it". 
In addition, let the program subtrack 1 from the counter every 
second(5 to 1) to show the status of the tracker.      	
  - Set the variable TEST, which will have the same value as the 
variable USER + the number of variables that do not include the name 
TEST, for example polz37.
- With the help of cURL fetch the website content of www.google.com and save it into file named website.txt
- In directory "Mapa" exists file count.txt
- Install packet "cowsay" and test it :)
- Write shortest command possible which will with the help of Python start a simple (integrated) HTTP server and will serve the files from the current directory on port 8000."""
