Purpose of this exercise

+

To learn how to use a few BASH commands.

+

Quick summary

+

You will use bash commands like: mv, grep, env etc.

+

Instructions

+ +

    +
  1. Log into your system and in your home folder you will find a directory called Mapa containing some 20 files.
    2. +
  2. Rename all files, by replacing all minus signs with underscores using the command: "rename 's/-/_/' *".
    3. +
  3. 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"
    4. +
  4. 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".
    5. +
  5. 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".
    6. +
  6. 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)"
