bash alias to unrar some format

Create faile:
touch unrar.sh && chmod +x unrar.sh
And then paste this in terminal:


cat <<EOF >>unrar.sh
#!/bin/bash

if [ -z "$1" ]
then
  echo "Paramather #1 is zero lenght"
else
  echo "Paramether #1 is \"$1\""
case $1 in
*tar) tar -xvf $1
;;
*bz2) bunzip2 $1
;;
*rar) unrar e $1
;;
*zip) unzip $1
esac
fi
EOF


After this open ~./bashrc or this you use and write this:

alias unrar='sh /path/to/unrar.sh/

Same alias start with use sintax:

unrar somefile.tar

#If not result save data in file
if [ $? -ne 0 ]
then
        date >> $filename
 
fi

#Function read line by line and play with vlc
while read line
do
 name=$line
 echo "Played - $line"
 vlc "$name"
 kill -9 vlc
done < $filename



#If you not use file do this in same line for play mp3 file:
find /home/borko/ -maxdepth 6 -type f -name *.mp3 -size -exec vlc {} \;
#This is a little function
