How to create bash-pattern to exclude a matching param in param expansionmatching?
I am missing how to create a bash-pattern that excludes a specific pattern. I.e. to ignore any file with '-IGN-' somewhere in the filename. The best I've come up with so far has been to use shell to build a pattern, but I know it is limited in functionality. I.e.: ls !($(echo *+(-IGN-)*|tr |)) I tried the above in a dir that has 2 files w/the pattern, and 532 w/o, and it worked, but how much of that was 'luck'? Is there a better bash-pattern that doesn't use tr and such? Thanks!

But we know it is simply that perl influence that dragged you that way. :-) This is a typical pattern for me. But I optimize it a little bit when possible by doing it this way. for var in *; do case $var in *-IGN-*) continue ;; esac whatever you wanted on the remaining files done Bob
[PATCH] bash: fix error path of getc_with_restart()
When read() returns with ERROR, local_bufused will be set
to -1; and if we return with local_bufused == -1 left,
the next time we call getc_with_restart(), the condition
(local_index == local_bufused || local_bufused == 0)
will not match, thus we get random data from localbuf[]
with local_index increased each time, eventually we may
access data beyond array localbuf[]. Fix it by resetting
local_index and local_bufused in case of read failure.
