Use variables inside YAD

I can't find a way to using variables inside YAD

I have the following script:

 #!/bin/bash   
USERS=$(awk '{print $1}' `pwd`/names.txt | sed -e ':a' -e 'N' -e '$!ba' -e 's/\n/!/g')

YAD=$(yad --title="Hello" \
--form \
--field="User:":CB \
'$USERS!New User')

My working file (names.txt) contains the following:

Ramiro  1234
Dalia   5678
Persona 9012

But that script results in a list with only two options: "$USERS" and "New User", not the contents of names.txt

Note that the correct syntax for a list in YAD is as follows:

YAD=$(yad --title="Hello" \
--form \
--field="User:":CB \
'Ramiro!Dalia!Persona!New User')
Solution

  • You are not allowing the variable expansion ($USERS) because of the single quotes. Use double quotes.

    Replace this:

    '$USERS!New User'

    With this:

    "$USERS!New User"
