Edit2: Solved! Thank you all! 🥰 I was supposed to put quotation marks around the command argument variable/substitute within the script, as in scanimage -d [device] –format=png -p -o “$1”
Edit: turns out it’s not the accented character, but the whitespace character in front of július.png, since the script doesn’t accept julius.png either.
#!/bin/bash
# name of the script is SCAN.bash
scanimage -d [device] --format=png -p -o $1
I have tried ’ ', " " and to escape it with \
./SCAN 'anyu 1988 július.png'
./SCAN "anyu 1988 július.png"
./SCAN anyu\ 1988\ július.png
But it throws argument without option. It works fine if I type it out instead of scripting.
The target language is Hungarian and I have generated the necessary locale.


If there is whitespace in the file name then you need whitespace inside the quotes, or escape the whitespace at the beginning of the filename with backslash-space
