@ Geoffrey
My scripts are not running in the Puppy environment but under Ubuntu 16.04 LTS in the folder ~ / .local / share / nemo / scripts. I could install Puppy to test on a USB stick, but the scripts should all be running under Ubuntu.

It could well be a language issue, the output from the shell 'command not found' in german is probably different, so you maybe just need to change this to german:

Code:
if grep -c 'command not found' /tmp/run-command-error; then


EDIT: Or put this on top of script:
Code:
export LANG=C

@ Fredx181
With the first code it has already worked. An error message will appear as desired.

@Alles
Thanks for the kind support.

Hi All,

Here's is an experiment of mine (a bit weird, I admit:) ):
Using yad with additional options, e.g. foregound and background color, gradient background and font setting.
Originally meant to be similar as gtkdialog-splash (part of the code taken from it), to be used for simple colored messages, but the good thing is that all yad options can be used also.
Using pango markup can override these extra options (see example 2 and 3 below).
Type ./yad-splash or ./yad-splash --help for the options.
Having installed "gtk2-engines-murrine" is recommended (for e.g. better looking buttons)
(in fact a custom theme file /tmp/gtkrc.yadsplash will be created and used)
You may want to set the icon theme on top of the script, by default it's set to Faenza
ICON_THEME="icon_theme_name"

Example 1, see screenshot 1:
Code:
./yad-splash --height=80 --width=200 --center --text "  \tYellow Text\n  \n  On Gradient Background  " --undecorated --button="gtk-close:1" --fg yellow --bg blue --bg_gradient true --bg_gradient_height 150 --font_name 'Sans Bold 9'


Example 2, see screenshot 2:
Code:
./yad-splash --height=100 --width=200 --center --text="<span size='large' foreground='red'><b>\tYad-Splash </b></span> \n \n\tBrown Text\n  \n  On Gradient Background  "  --undecorated --no-buttons --fg "#4B200A" --bg "#F4E48F" --bg_gradient true --font_name 'Sans Bold 10' --bg_gradient_height 80


Example 3, (example from earlier in this thread, with added color options) see screenshot 3:
Code:
./yad-splash --title="Golf Club" --height=200 --width=400 --text="<span foreground='blue'><b><big><big>Please enter your details:</big></big></b></span>" \
--form \
--field="<b><big><big>Golflink Number</big></big></b>" \
--field="<b><big><big>Score</big></big></b>" --fg white --bg grey --bg_gradient true --bg_gradient_height 120 --font_name 'Sans Bold 9'

PostPosted: Wed 26 Apr 2017, 08:39    Post subject: youtube-dl  

Hello everybody,
With the command

Youtube-dl -f 'bestvideo [ext = mp4] + bestaudio [ext = m4a] / bestvideo + bestaudio' - merge output format mp4 "https://www.youtube.com/watch?v=4x0aYzcxmjk"
Downloade I from the Ubuntu Terminal the selected file in the best possible quality in the current directory. Has anyone an idea how I can make the whole thing with yad more comfortable, whereby the url address is of course variable.
Many Thanks

Hi achim, this should do it (with progressbar)
I took parts from here:
https://github.com/Misko-2083/scripts/blob/7ef871dd121e1cb3dbdb2b21ab61ffeeb1d86110/youtube

Code:
#!/bin/bash

# Partly taken from here (and simpified for just one video): https://github.com/Misko-2083/scripts/blob/7ef871dd121e1cb3dbdb2b21ab61ffeeb1d86110/youtube

# function download
download() {
  youtube-dl -f 'bestvideo [ext = mp4] + bestaudio [ext = m4a] / bestvideo + bestaudio' --merge-output-format mp4 --newline -i -o "%(title)s.%(ext)s" "$1" 2>&1 \
  | while read line; do
     if [[ "$(echo $line | grep '[0-9]*%')" ]];then
        percent=$(echo $line | awk '{print $2}')
        echo "${percent%.*}%"
     fi

     if [[ "$(echo $line | grep '\[download\]')" ]];then
        progress=$(echo $line | awk '{$1=""; print $0}')
        echo "#$progress"
     fi
   done

    RET_YT="${PIPESTATUS[0]}"
    if [[ "$RET_YT" = 0 ]]
      then
          echo "100%"
          echo "#Download completed."
         
    else
          echo "#Download error."
    fi
}

# Enter URL
URL=$(yad --title="YouTube Downloader" --height 100 --width 400 ---center --entry --text=" Please enter url below")

if [ -z "$URL" ]; then # vovchik, if empty, then exit
   exit 1
else
   # Download with progress bar
   download $URL | yad --window-icon="$ICON" \
      --progress \
      --image=browser-download \
      --title="YouTube Downloader" \
      --center --borders=6 \
        --text="  Downloading: $URL" \
        --button="gtk-cancel:1"
fi


EDIT: Modified to check if $URL is empty, suggestion from vovchik, see below post

Fred

Dear Fred,

How about this at the end, to prevent an unnecessary "downloading" window when the URL is empty?


Code:

if [ -z "$URL" ]; then
   exit 1
else
   # Download with progress bar
   download $URL | yad --window-icon="$ICON" \
      --progress \
      --image=browser-download \
      --title="YouTube Downloader" \
      --center --borders=6 \
        --text="  Downloading: $URL" \
        --button="gtk-cancel:1"
fi


With kind regards,
vovchik

Very Happy Glad to help.

Hey fredx181, how would you end the youtube-dl process in the folowing script? Without "killall youtube-dl" of course.

Code:
#!/bin/bash

export ytdownload='@bash -c "download_video %1"'

export ytdpipe=$(mktemp -u --tmpdir pmrp.XXXXXXXX)
mkfifo "$ytdpipe"

trap "rm -f $ytdpipe" EXIT

ytdkey=$(($RANDOM * $$))

function download_video
{
  echo "2:@disable@"
  echo "#Preparing to download" >> "$ytdpipe"
  youtube-dl -f 'bestvideo [ext = mp4] + bestaudio [ext = m4a] / bestvideo + bestaudio' --merge-output-format mp4 --newline -i -o "%(title)s.%(ext)s" "$1" 2>&1 \
  | while read line; do
     if [[ "$(echo $line | grep '[0-9]*%')" ]];then
        percent=$(echo $line | awk '{print $2}')
        echo "${percent%.*}%" >> "$ytdpipe"
     fi

     if [[ "$(echo $line | grep '\[download\]')" ]];then
        progress=$(echo $line | awk '{$1=""; print $0}')
        echo "#$progress" >> "$ytdpipe"
     fi
   done

    RET_YT="${PIPESTATUS[0]}"
    if [[ "$RET_YT" = 0 ]]
      then
          echo "100%" >> "$ytdpipe"
          echo "#Download completed." >> "$ytdpipe"   
    else
          echo "#Download error." >> "$ytdpipe"
    fi

    echo "2:$ytdownload"
}
export -f download_video

function ytdl_version () {
    echo "#Checking youtube-dl version" >> "$ytdpipe"
    wget --spider --user-agent="Mozilla/5.0 Gecko/20100101" --timeout=30 -q "https://rg3.github.io/youtube-dl/" -O /dev/null
    if [[ "$?" -ne "0" ]]; then
       echo "#Can't connect to youtube-dl server site" >> "$ytdpipe"
    fi
    ytdlcv=$(youtube-dl --version)
    ytdllv=$(wget -O- -q "https://rg3.github.io/youtube-dl/update/LATEST_VERSION")
    if [[ "$ytdlcv" == "$ytdllv" ]]; then
   echo "#youtube-dl is up-to-date"  >> "$ytdpipe"
    else
   echo "#youtube-dl update is available" >> "$ytdpipe"
    fi
}

exec 3<> $ytdpipe

yad --plug="$ytdkey" --tabnum=1 --form --field "Enter video url":CE "https://www.youtube.com/" \
    --image=browser-download --image-ontop --field="Download!gtk-download:fbtn" "$ytdownload" &

yad --plug="$ytdkey" --tabnum=2 --window-icon="$ICON" \
      --progress  --borders=6 <&3 &

  ytdl_version &

yad --paned --key="$ytdkey"  \
    --button="Stop":"killall youtube-dl"  --text="" --width=500 --height=200 \
    --title=$"YouTube Downloader" --image=browser-download --window-icon="$ICON" --center

exec 3>&-


Edit: Asked the developer how to kill all the processes on paned window close. Rolling Eyes

The below works for me (although probably can be better, more simple), but hey! I thought you were the expert Smile
Nice script, btw Wink

EDIT: Changed the "get_pid_and_kill" function to this:
Code:
function get_pid_and_kill () { # fredx181 exec function Stop button (see below)
# export pidytdl="`ps -eo pid,cmd | grep "youtube-dl -f bestvideo \[ext = mp4\] + bestaudio \[ext = m4a\] / bestvideo + bestaudio --merge-output-format mp4 --newline -i" | grep -v grep | awk '{ print $1 }' 2> /dev/null`"
# This will give the unique pid, better than above
export pidytdl="`ps -eo pid,cmd | grep "youtube-dl" | grep "$1" | grep -v grep | awk '{ print $1 }' 2> /dev/null`"
kill $pidytdl
}


EDIT2: no, still not good, running the script twice with different URL clicking the Stop button kill both youtube-dl processes, so.... I don't know how to get the unique pid, anyone?

EDIT3: Couldn't let go Smile Now it should be fine, actually it's the pid of function 'download_video' that gets killed when clicking the Stop button

Code:
#!/bin/bash

# fredx181, create tempfile, the pid of the function 'download_video' will be written to it
export PIDYTDL=`tempfile 2>/dev/null`
 
export ytdownload='@bash -c "download_video %1"'

Added another named pipe. You can never make enough of those. Very Happy
This way I can check the exit status of youtube-dl.
or in other words, if the user has canceled and if download has failed.
Also added a check if url is correct "wget -q --spider $URL" (nothing fancy) Smile
Tested, it kills only the current process, leaves that one in another window alone.
Could't find a way to kill the download process in case I click on the window button [X]. Hey, you can't have it all. I whish that yad paned dialog could nuke everything on exit.

This was fun Smile
Back to that internet radio Yad UI I was working on...http://i.imgur.com/oEHIhXP.png

EDIT: I had a huge headake last night. Rolling Eyes
Forgot to say this: Thank you Fred.
Oh, man, things with paned dialogs are complicated. Laughing

PostPosted: Wed 17 May 2017, 09:32    Post subject: Fax with YAD  

Hello everybody,

I use the WF-3520 multifunction device from Epson among other things also to fax. There is a FAX driver to the device, which I call from the terminal under Ubuntu 16.04 with the command "epfax -P pc-fax -o fax-number = 0236112345678 testfax2.pdf" and send the document.
For some time I have been working enthusiastically with YAD and would like to run this action via a script. The name and fax number are to be queried via a window and then transferred to the command. A good thing would be a history, so I do not have to enter everything again next time. For example, to print a selected file, I use this script:

#! / Bin / bash

Lpoptions -d WF-3520-Series
For i in $ NEMO_SCRIPT_SELECTED_URIS
do
Soffice --invisible --norestore -p $ i
done

This is how I would like to use the FAX driver.

Has anyone from the experts here present a suggestion to the settlement with YAD?

I thank you in advance.

PostPosted: Fri 19 May 2017, 09:50    Post subject: Fax with YAD  

Hello experts,

To my solution "fax with yad" I have put together the code listed below. It works as far as history. If you have any suggestions for improvement, I would be very happy.

Achim

Code:

#! /bin/bash

XTERM="xterm"

# create history file
mkdir -p ${XDG_CACHE_HOME:-$HOME/.cache}/
HISTFILE=${XDG_CACHE_HOME:-$HOME/.cache}/ix1-run.history
touch $HISTFILE

# create and run dialog
TITLE="Faxprogramm vorbereiten..."
TEXT="\nFaxnummer eingeben und Enter drücken:\n"
fnr=$(yad --width=500 --center --window-icon="gtk-execute" --name="${0##/}" --title="$TITLE" --text="$TEXT" --image="gtk-execute" --editable --entry --rest $HISTFILE)
