lets play a game

[kerry_s]

the mission is simple, check a directory for content, if there is content, replace a line in a file.
i'm thinking maybe script run with cron?

how would you do it?

what i'm actually doing is making a trash app/launcher just for the heck of it. i just want a working trash icon on my dash to dock.

the line i want to swap back & fourth

Icon=user-trash
to
Icon=user-trash-full

my trash.desktop

[Desktop Entry]
Type=Application
Name=Trash
Comment=Trash
Icon=user-trash
Exec=nautilus /home/user/.local/share/Trash
Categories=Utility;
Actions=trash;

[Desktop Action trash]
Name=Empty Trash
Exec=/home/user/Documents/trash.sh

my trash.sh

#!/bin/sh
rm -rf /home/user/.local/share/Trash/*

truth is i haven't done scripting in ages, i'm trying to remember, but my brains just not there. i'm not sure what to use.
maybe something like:

#!/bin/sh
path=/home/user/.local/share/Trash
1=Icon=user-trash
2=Icon=user-trash-full
icon=/home/user/.local/share/applications/trash.desktop

if [ ! "$(ls -A $path)" ]
then
    sed -i "/$1/c $2" $icon
else
    sed -i "/$2/c $1" $icon
fi

[kerry_s]

working script:

#!/bin/sh
cp /home/user/.local/share/applications/trash.desktop /home/user/.local/share/applications/trash.desktop.bak
path=/home/user/.local/share/Trash/files
icon=/home/user/.local/share/applications/trash.desktop
icon2=/home/user/.local/share/applications/trash.desktop.bak

if [ "$(ls -A $path)" ]; then
    sed 's/user-trash/user-trash-full/' $icon2 > $icon
else
    sed 's/user-trash-full/user-trash/' $icon2 > $icon
fi

[kerry_s]

alright, i got working trash on my dash to dock.
i'm sure there are other ways to do it, this is the way i did it trying to keep it simple with the same results every time, doesn't spawn the same process over & over, doesn't drive the memory up. doesn't screw up the trash.desktop, which is why i dropped sed for cat.
anyways enjoy.

updated i just use 3 files now

i guess i'll star with the scripts.

trash.sh -r <-checks for trash & changes icon
trash.sh -e <- empties trash & changes icon back.
trash.sh -d <-add this to startup

trash.sh

#!/bin/bash
path=/home/user/.local/share/Trash/files
icon=/home/user/.local/share/applications/trash.desktop

while getopts "red" opt; do
	case $opt in
    r)
	if [ "$(ls -A $path)" ]; then
		echo -e '[Desktop Entry]\nType=Application\nName=Trash\nComment=Trash\nIcon=user-trash-full\nExec=nautilus /home/user/.local/share/Trash/files\nCategories=Utility;\nActions=trash;\n\n[Desktop Action trash]\nName=Empty Trash\nExec=/home/user/Documents/trash.sh -e\n' > $icon
	fi
	;;
    e)
	rm -rf /home/user/.local/share/Trash/files/* && rm -rf /home/user/.local/share/Trash/info/* && echo -e '[Desktop Entry]\nType=Application\nName=Trash\nComment=Trash\nIcon=user-trash\nExec=nautilus /home/user/.local/share/Trash/files\nCategories=Utility;\nActions=trash;\n\n[Desktop Action trash]\nName=Empty Trash\nExec=/home/user/Documents/trash.sh -e\n' > $icon
	;;
    d)
	while sleep 60; do (/home/user/Documents/trash.sh -r &) ; done
	;;
  esac
done

trash.desktop <-this is the applet/application that you would add to dock

[Desktop Entry]
Type=Application
Name=Trash
Comment=Trash
Icon=user-trash
Exec=nautilus /home/user/.local/share/Trash/files
Categories=Utility;
Actions=trash;

[Desktop Action trash]
Name=Empty Trash
Exec=/home/user/Documents/trash.sh -e

I am a tad OCD when it comes to my Recycle Bin. I always delete completely, never send anything there

I am a tad OCD when it comes to my Recycle Bin. I always delete completely, never send anything there

i use to do that, but now i'm old & make more mistakes. my attention span is all over the place sometimes.

[kerry_s]

i updated post #3 cause i changed from cat file > file to echo > file, getting rid of the 2 spare copies, now i'm down to 4 files to have a working trash icon.

i'd like to combine trash.sh & trash-icon.sh to 1 file if i can.

[kerry_s]

okay i combined trash.sh & trash-icon.sh in to 1 file. i'll fix post #3 with new file.

trash.sh -r <-checks for trash & changes icon
trash.sh -e <- empties trash & changes icon back.

#!/bin/bash
path=/home/user/.local/share/Trash/files
icon=/home/user/.local/share/applications/trash.desktop

while getopts "re" opt; do
	case $opt in
    r)
	if [ "$(ls -A $path)" ]; then
		echo -e '[Desktop Entry]\nType=Application\nName=Trash\nComment=Trash\nIcon=user-trash-full\nExec=nautilus /home/user/.local/share/Trash/files\nCategories=Utility;\nActions=trash;\n\n[Desktop Action trash]\nName=Empty Trash\nExec=/home/user/Documents/trash.sh\n' > $icon
	fi
	;;
    e)
	rm -rf /home/user/.local/share/Trash/files/* && rm -rf /home/user/.local/share/Trash/info/* && echo -e '[Desktop Entry]\nType=Application\nName=Trash\nComment=Trash\nIcon=user-trash\nExec=nautilus /home/user/.local/share/Trash/files\nCategories=Utility;\nActions=trash;\n\n[Desktop Action trash]\nName=Empty Trash\nExec=/home/user/Documents/trash.sh\n' > $icon
	;;
  esac
done

i went ahead & added the watch.sh into trash.sh to just make it 2 files for a working trash can app.

Nice project, well executed

Nice project, well executed

thank you, i was just bored & it didn't seem like it would be to complicated. i still had to rtfm cause there are a lot of ways of doing it, i just wanted simple so any 1 could use it just changing the "user" name & maybe path.

i suppose i could make that easier using $user at the top.

i'll fix it later, i gotta go get my weekly blood test, i so hate the smell of hospitals now.
