Greetings,
I have a working script checking mimetypes i.e. `text/x-diff`;
`image/svg+xml` etc.
=================================
1 #!/bin/bash
2
3 _Bold="\e[1m"
4 _unBold="\e[22m"
5 _Blue="\e[34m"
6 _uC="\e[39m"
7
8 mimetype="$1"
9 output="${_Bold}Testing MimeType${_unBold}:\t${mimetype}\n\t-------------"
10
11 get_default()
12 {
13 xdg-mime query default "$1"
14 }
15
16 alias_of=`grep "^$mimetype " /usr/share/mime/aliases | cut -d' ' -f2`
17 if [ -n "$alias_of" ]; then
18 default=`get_default $alias_of`
19 output="$output\nWhich is an alias of:\t$alias_of\t->
${default:-"none"}"
20 else
21 output="$output\nWhich is not an alias."
22 alias_of=$mimetype
23 fi
24
25 while : ; do
26 subclass_of=`grep "^$alias_of " /usr/share/mime/subclasses |
cut -d' ' -f2`
27 if [ -n "$subclass_of" ]; then
28 default=`get_default $subclass_of`
29 output="$output\nWhich is a subclass of:\t$subclass_of\t->
${default:-"none"}"
30
31 alias_of=$subclass_of
32 else
33 output="$output\nWhich is not a subclass"
34 break
35 fi
36 done
37
38 echo -e $output | column -t -s $'\t'
=================================
Output without bold (line 8) is as expected but with bold, the column
is widened/broken.
I have removed the rest of the formatting in my example, but with
colors added it gets much worse.
I think I have narrowed it down to the `column` somehow including the
escape sequences in its spacing calculation? The same thing happens in
xterm, gnome-terminal and urxvt.
Is this expected behaviour? I'm learning a lot but sometimes I get a
headscratcher like this one.
Thank you for your time.
Sincerely,
Michael Heyns
