sed command is replacing the replaced text?
I am writing a bash script to rename icons. Specifically I am trying to change "icon-close-m" to "icon-close icon-size-medium" in HTML files. (though it could contain any substring besides "close", as noted by the [a-z] in the line below)
It works when I run this command from the command line:
sed -i -e "s/(icon-[a-z]*)-m[^e]/1 icon-size-medium/g" ./app/index.html
result:
icon-close icon-size-medium
but when I run it from the script it changes it to this:
icon-close icon-sizeedium
Here is an example of text that should change:
<span class="icon-close-m"></span>
should become:
<span class="icon-close icon-size-medium"></span>
It appears to be going through and replacing the -m in the new replacement, after the initial replacement. It is only doing this when the command is implemented in a bash script. I have not seen this happen before and I haven't seen any similar issues on SE/SO. Note that this command is not inside of any sort of loop.

Sure thing @steeldriver. Just edited. As far as I can tell, it goes through and addsicon-size-mediumto the string. because that string has the letter e followed by -m, I believe it is replacing it because it matches the regex requirement.

I wonder if you have some stray control characters in thesedexpression in the script? You would get that result if the replacement text was/1 icon-size-m^H^Hedium/where^His a literal backspace character.

@Kusalananda That's a good call. How can I check for/remove stray control characters?

The simplest would be to just retype the command in the script. Otherwise, it would depend on your editor. You could also useod -aon the script to see if you can spot any odd characters.
