Pattern substitution insensitive to case?

2013-09-11 Thread Davide Baldini 

Hi,

Bash doesn't seem to provide a handy way to perform search-and-replace 
on strings in a case-insensitive manner.


The parameter expansion "${parameter/pattern/string}" is not influenced 
by the shell options "nocaseglob" and "nocasematch", at least in Bash 
version 4.2.37. Is this intended?


My temporary workaround is to run the search-replace function on GNU 
'sed' with the unportable 'I' flag to ignore case.

Yes, neither option applies to pattern replacement word expansion.  I will
consider that extension for a future version of bash.

Thanks for the report.  This has been fixed for the next bash release,
and the fix is already in the bash devel git tree.
