Hi,
The nature of my query makes it difficult to figure out if the
question has been asked already. If so, I'd be grateful if you could
direct me to that thread.

I have a shell script (yaourt on Arch Linux) that launches a text
editor for some files (the names could be PKGBUILD, *.install, or
something else). The opened file is either a Bash script or has a bash-
like syntax. If I want syntax highlighting, I have to click on
Language->Shell. What command-line arguments could I use to launch
scite such that the subsequent "-open:xxx" would pre-select the Shell
lexer for xxx?

Going through http://www.scintilla.org/SciTEDoc.html and
http://www.scintilla.org/SciTEFAQ.html did not help.
