I am using GnuWin32 sed and am having trouble with the regexp - i.e., they don't behave the same way as in UNIX (POSIX and and all that). I have a stream of data, e.g.:
11111'222?'22'33?'333'44444'55555'
I want to insert a \n after those apostrophes that are *not* preceded by a ?.

DELETE FROM /*<workDB>*/epd_test./*<multi>*//*<version>*/epd_tbl1 ALL; into

ncdestroy
NCDESTROY(1) BSD General Commands Manual NCDESTROY(1)NAME
ncdestroy -- Destroy kernel NFS credentials
SYNOPSIS
ncdestroy [-v] [-P] [path [path...]]
DESCRIPTION
ncdestroy invalidates the caller's kernel GSS credentials for any of the specified path's associated NFS mounts. If no paths are specified
then all the caller's associated credentials for all NFS file systems are destroyed.
When a nfs file system is mounted using a GSS mechanism (currently only Kerberos is supported) through the ``sec='' option or by the export
specified on the server, the resulting session context is stored in a table for each mount. If the user decides to finish his or her session
or chooses to use a different credential, then ncdestroy can be called to invalidate those credentials in the kernel. New credentials can be
obtain (typically by calling kinit) and those credentials can be used when accessing the mount.
The options are as follows:
-v Be verbose and show what file system is being operated on and any resulting errors.
-P If the trailing component resolves to a symbolic link do not resolve the link but use the current path to determine any associate NFS
file system.
EXAMPLES
If leaving for the day:
$ kdestroy -A
$ ncdestroy
Lets say a user does
$ kinit user@FOO.COM
And through the automounter access a path /Network/Serves/someserver/Sources/foo/bar where the mount of /Network/Servers/some-
server/Sources/foo was done with user@FOO.COM.
$ cat /Network/Servers/someserver/Sources/foo/bar
cat: /Network/Servers/someserver/Sources/foo/bar: Permission denied
The user realizes that in order to have access on the server his identity should be user2@BAR.COM. So:
$ kdestroy -A
$ kinit user2@BAR.COM
$ ncdestroy /Network/Servers/someserver/Sources/foo
Now the local user can access bar
NOTES
In the above example the user destroyed all credentials so the only credential to choose was new credential user2@BAR.COM. However, if
accessing the server with user@FOO.COM was done by getting a cross realm TGT to obtain the service ticket nfs/some.server.fqdn@BAR.COM, then
it won't be necessary to use kdestroy. The GSS infrastructure will prefer to use credentials in the same realm as the service.
DIAGNOSTICS
The ncdestroy command will exit with 1 if any of the supplied paths don't exist. If all paths exist or no paths are given the exit status
will be 0.
SEE ALSO kinit(1), kdestroy(1), mount_nfs(8)BUGS
There should be an option to kdestroy to destroy cached nfs contexts.
