zenity script

[Neal ManBear]

The ls command in the script in the terminal will list the plymouth themes in the terminal, but running the script brings up an empty list box.

Code: [Select]

# temp folder
if [ ! -d $HOME/.config/tmp ]; then mkdir -p $HOME/.config/tmp; fi
LIST="$HOME/.config/tmp/lst01"

# delete old theme list
if [ -f "$LIST" ]; then rm -f "$LIST";fi

# create plymouth-theme list
THEMELIST=`ls -d /usr/share/plymouth/themes/*/*.plymouth`
for i in $THEMELIST; do echo $i | cut -d/ -f5 >> "$LIST";done

cd /tmp
echo 'XX=$(zenity --title "Select a Plymouth Theme" --text "Please select a plymouth theme or press Cancel to quit.\nNOTE: you must reboot to apply the new plymouth theme\!" --list --height 300 --radiolist --column "Select" --column "Plymouth Theme" ' > tt1

The error message in terminal is

Code: [Select]

ls: cannot access /usr/share/plymouth/themes/*theme: No such file or directory
cat: /root/.config/tmp/lst01: No such file or directory
I'm pretty sure I'm missing something obvious, but I can't see it.

Neal,

you specified the cut command with -f5, but the file names are in the 7th position (the 1st element preceeds the first "/").

When I try

Code: [Select]

echo "/usr/share/plymouth/themes/details/details.plymouth" | cut -d/ -f5
I get "themes", but when I specify

Code: [Select]

echo "/usr/share/plymouth/themes/details/details.plymouth" | cut -d/ -f7
it gives me the actual file names.

By the way - wouldn't the  basename command give you more flexibility? Just a thought

I made those changes, but the result is the same as before.

Could you write a basename script that would work? I can't. I wish I could.

[tschommer]

I think this should work:

Code: [Select]

for i in $THEMELIST; do basename $i >> "$LIST";done

[Neal ManBear]

No. Same results.

[tschommer]

Hmm, strange. I got the file list saved correctly in $HOME/.config/tmp/lst01:

Code: [Select]

[torsten@schommer ~]$ cat .config/tmp/lst01
details.plymouth
PCLinuxOS.plymouth
text.plymouth
[torsten@schommer ~]
But I only got the script to work with a variable ($LST) containing the values (including the "FALSE" directive for the 1st column). Also, I haven't used zenity myself, so I only got it to work without the "echo ... >tty1".

The complete code (with a few comments added):

Code: [Select]

# temp folder
if [ ! -d $HOME/.config/tmp ]; then mkdir -p $HOME/.config/tmp; fi
LIST="$HOME/.config/tmp/lst01"

# delete old theme list
if [ -f "$LIST" ]; then rm -f "$LIST";fi

LST=""

# create plymouth-theme list
THEMELIST=`ls -d /usr/share/plymouth/themes/*/*.plymouth`

# include "FALSE" for the first column and the file name for the second one
for i in $THEMELIST; do LST="$LST FALSE `basename $i`";done

# save the list to the file specified above
echo $LST > $LIST

cd /tmp
XX=$(zenity --title "Select a Plymouth Theme" --text "Please select a plymouth theme or press Cancel to quit.\nNOTE: you must reboot to apply the new plymouth theme\!" --list --height 300 --radiolist --column "Select" --column "Plymouth Theme" $LST)
Hope this gives you something to work with.

The script, so far, is attached. I changed the list part of the script to use what you posted, but I'm still getting the same errors.

[tschommer]

Neal,

one thing I noticed: you insert a "FALSE " in front of the file list, but a "FALSE " is already in the variable for each option (done in the for-loop => LST="$LST FALSE `basename $i`), so that shouldn't be needed. In my case the variable $LST contains:

Code: [Select]

FALSE details.plymouth FALSE PCLinuxOS.plymouth FALSE text.plymouth
You want to create a script /tmp/tt0, but I just can't figure out what it's supposed to contain (besides the #!/bin/bash and the ); at the end) - could you just give me an example for what /tmp/tt0 should look like?

Maybe you could also give me a hint where the currently used theme is stored, then maybe I could come up with something...?

We'll get to the bottom of this!

I guess I was trying to do the script similar to lxcursor. (attached)

Hi Neal,
for what you need it?

The themes at last works for me perfectly...

[tschommer]

That's actually a pretty good example. Here's what I got (and it seems to work  )

[tschommer]

Neal,

I just made the following changes to the script so that only the theme name would be displayed (with the ".plymouth" suffix):

1. changed line 56 from
     

Code: [Select]

for i in $THEMELIST; do echo `basename $i` >> "$LIST";done    to
     

Code: [Select]

for i in $THEMELIST; do echo `basename ${i%.plymouth}` >> "$LIST";done
2. Removed the original line 73 to determine the directory name of the theme and added the ".plymouth" suffix for the soft link:
     

Code: [Select]

ln -fs /usr/share/plymouth/themes/$PLY_SELECT/$PLY_SELECT.plymouth $HOME/.plymouth/default
If I can help out any more I'll be glad to.

Torsten

[Neal ManBear]

Thank you very much, Torsten! WooHoo! It appears to be working. I need to reboot to check, but the script is working as for as can be seen. Be back soon.

[Neal ManBear]

Hi Neal,
for what you need it?

The themes at last works for me perfectly...

I'm trying to create a GUI for changing between plymouth boot themes.

[Neal ManBear]

The theme didn't change.
