I recommend you use Visual Studio Code (not Visual Studio).

FWIW, I use Visual Studio Code (VSC) full time and never have a problem. VSC is incredible.

Make sure you get the right VSC extensions!

Ha! Another potential prospect to convert to the cult. ;-))

The command is (in command mode type ":" to get into colon-mode and then) set list. To switch it off again type :set nolist.

PS: in the script i oversaw another error: "if" is one time written "If" (capitalised "I"), which also leads to a syntax error.

You need to change given input of advertisement removed by moderators
which have given:
Code:
read file_name
if [ -e $file_name ]
then
echo "$file_name found"
else
echo "$file_name not found"
fi

If you can change this $ fine name and other is Echo condition.

Windows text editors and UNIX text editors disagree on what a line is.

In windows, a line is a bunch of characters followed by two nonprinting characters, \r \n.
In UNIX, a line is a bunch of characters followed by one nonprinting character, \n.

All these \r's are basically garbage which Windows insists on adding to the end of every line.
