+<h2>Purpose of this exercise</h2>
+ <p>To learn how to use a few BASH commands.</p>
+<h2>Quick summary</h2>
+ <p>You will use bash commands like: mv, grep, env etc.</p>
+<h2>Instructions</h2>
+
+<h2><ol>
+ <li>Log into your system and in your home folder you will find a directory called Mapa containing 20 files.</li>
+ <li>Rename all files, by replacing all minus signs with underscores using the command: "rename 's/-/_/' *".</li>
+ <li>Remove all files from /home/user/mapa/mojimenik into /home/user/novi using command: "mkdir-p /home/user/novi && mv /home/user/mapa/mojimenik/* /home/user/novi"</li>
+ <li>Write all regular files containing a string "mama" into file "mama.txt", and all errors in file "napake.txt" by using: "find . -type f | grep mama 1> mama.txt 2> napake.txt".</li>
+ <li>Inspect /var/log/syslog for 5 seconds and in case a string"zmeda" appears in syslog, write "imam ga". Also while inspecting syslog, reduce the counter by every second using a command: "for i in 5 4 3 2 1; do echo $i; echo $(sed -n "$i p" /var/log/syslog | grep zmeda > /dev/null && echo "imam ga"); sleep 1; done".</li>
+ <li>Set a variable TEST to the same value as the variable USER + the number of environmen variables not containing string "TEST" in their names, by adding ~/.bashrc to the end of the file: "export TEST=$USER" + "$(env | grep -v TEST | wc -l)"</li>

+Log into the system.

+ -rename all the files in a such a manner that u replace al the minuses with an underscore
+ -write the shortest command possible to move all the files from /home/user/mapa/mojimenik to home/user/novi
+ -write a command which (with the help of the command grep) in the file "mama.txt" writes all the normal files (not hidden) in the current directory that contain the word "mama", and any mistakes to the file "napake.txt" (such as that the files are actually directories or wrong symbolic links)
+ -write a command which will follow the content of /var/log/syslog for 5s. In the case that the expresion "zmeda" appears in the syslog print out "imam ga". Also for every second of following the syslog print out the a number, counting down from 5 to 1.
