nano keeps leaving green spaces

Altiris · 06-25-2016, 05:21 PM

I have noticed this only with Slackware, whenever I use nano, many times I hit space bar and a green box occupies the space and actually messes up .sh files whenever those green boxes are there. Another problem that occurs after the green box is that instead of keeping a continuous line the line will get jumped to the second line. Why does this happen? This is occurring when I SSH mostly either from an arch linux or ubuntu client, it doesn't matter. No other distro has had these weird green text boxes showing up or spacing messed up with nano. is there a setting for me to change somewhere?

/etc/nanorc should be where to look.

Sorry but that does not help. I tried looking for trailing whitespace in /etc/nanorc but I did not find anything.

The green boxes at the end of lines show the presence of trailing space characters. They are a consequence of syntax highlighting in nano. In /etc/nanorc, there is

Code:

## To include all existing syntax definitions, you can do:
include "/usr/share/nano/*.nanorc"

If you run the command

Code:

grep -A1 '# Trailing whitespace' /usr/share/nano/*.nanorc

you will see the entries.
The trailing space characters are generally inconsequential, and do not indicate corruption of your file.

The second issue you have is that nano is automatically breaking long lines.
