Can somebody tell me what type of patterns are supported in l, in the
$x:s/l/r syntax?
I'd like to do something like:
$x:gs/[^A-Za-z0-9]/_
to replace all characters except for the ones listed with underscore.

Hi Björn :)

Read the info manual, section 'History Expansion', node
'Modifiers'. Scroll down a bit and you'll find the answer. The 'l'
part is not a regex :(

¿How about using ${x//PATTERN/REPLACEMENT}? Then you can use the
patterns valid for filename generation (sort of a regex, more or less
powerful depending on the option 'EXTENDED_GLOB'. For your example, I
would do:
print ${x//[^[:alnum:]]/_}
Whether to use 'print' or not is up to your particular use. The
double '//' is to say 'make substitutions global, not only the
first', and the 'regex' is to say 'al non alphanumeric characters'.
Hope this helps.
