Functions in bashrc. One more simple thing

In .bashrc you can describe functions.



Why am I doing this? If you are missing alias, it is not necessary to write a single-line script.



You can add a function in .bashrc, for example, to get an external ip address



wanip() {

wget -q -O - checkip.dyndns.com | awk '{print $6}'| sed 's/<.*>//'

}



In the command line, wanip will show your external ip address.

')

And it is better to put it in a separate file, for this add in .bashrc



if [ -f ~/.bash_func ]; then

. ~/.bash_func

fi



.bash_func - the name of the file, where we will write functions.
