Hope that helps I'm trying to extract a specific string value from a text file and then remove the backslash from him. the name of the value is "display_url" , Change your script into:
code :
url=$(grep -oP '(?<=display_url":")[^"]+' /var/scripts/string.txt )
sed 's/\\//g;s@^@https://@' <<< "$url"

it fixes the issue I have a lot of files that have a shared pattern in their name that I would like to remove. For example I have the files, "a_file000.tga" and "another_file000.tga". I would like to do an operation on those files that would remove the pattern "000" from their names resulting in the new names, "a_file.tga" and "another_file.tga". , Try this (this works in plain old Bourne sh as well):
code :
for i in *000.tga
do
    mv "$i" "`echo $i | sed 's/000//'`"
done

wish help you to fix your issue I'm almost done with using bash, but the last thing I need to do is to do a regex replace on a string in bash. I have the PHP equivalent here , Try the following:
code :
echo "some string" | tr -d -c ".[:alnum:]"

I wish this helpful for you You'll want to use ast.literal_eval here, which will convert the string to a tuple:
code :
import ast
filecontent = ast.literal_eval(filename.read().strip())
name, weeks_worked, weekly_payment = filecontent
