Sharing my new script - making symbolic links

[edcompsci]

Every time I use a script I find online I think, "Well what can I share back?"

This one simply prompts the user to put symbolic links into a folder for use as wallpapers, to take advantage of the randomly changing backgrounds option in Desktop Settings.

I hope others enjoy it. Not a huge learning curve.

Code: Select all

#!/bin/bash

# uses arithmetic... echo "$(($a + 1))"
clear

linkfolder='/path/to/folder/' 
echo "enter the number of the last symbolic link in the $linkfolder folder"
read lastnum
echo "The number you entered is $lastnum"
i="$(($lastnum + 1))"
echo "The next symbolic link will be number $i"

echo "How many wallpaper symbolic links do you want to make?"
read numlinks
echo "You entered $numlinks"
j="$(($i + $numlinks))"
echo "The number of the last link you make will be $(($j))"


####################################### loop ###########################################
while [ $i -lt $j ]
do
echo "enter the path to image $i"
read path2image
echo "making symbolic link..."
ln -s "$path2image" "$linkfolder/$i"
echo "Symbolic link made.  Verify if tihs is the first time running this script."
((++i))
done
#################################### end loop #######################################

Thank you; very useful for new scripters. One remark: you can in arithmetic expansion $((..)) leave out the $ for variables such as lastnum.

Please properly indent your code; you and any readers of your code will thank me later.

Example of indenting a statement and a loop:

Code: Select all

if CONDITION; then
	COMMANDS
fi

while CONDITION; do
	COMMANDS
done

Whether you use tabs or any number of whitespaces, try to be consistent.

Thank you; very useful for new scripters. One remark: you can in arithmetic expansion $((..)) leave out the $ for variables such as lastnum.

Fun fact: there are other times you don't need the sigil ($), such as a subscript ${Here[is_a_variable]} and a substring ${Like:These:Variables}.

Thanks for the replies/tips

so this puts wallpapers on a folder background of commands or things new users use and see it as a refresher in backgrounds?
