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!

Slight improvement -- but still not a direct bash pattern:

!($(printf "%s|" *+(-IGN-)*))

for $var in *; do
  case $var in
*-IGN-*) ;;
*) # whatever you wanted on the remaining files
  ;;
  esac
done

What's wrong with:

!(*-IGN-*)

ls !(*-IGN-*)

Seems perfect...

Had a slightly more complex usage (filtering MS packages) but
it seems to work:
ls !(*_@(en-us|none)*)

Thanks!

A couple of minor syntax errors in the above.  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

[PATCH] bash: fix error path of getc_with_restart()

[Yong Zhang]

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.
