So your > behavior sounds absolutely normal. Reading a registry key isn't like reading a stream. There's no file position pointer and no EOF mark. You read all (or as much as you want) of the data in one operation.

Check this: [EMAIL PROTECTED] ~> cd /proc/registry/ [EMAIL PROTECTED] /proc/registry> ls HKEY_CLASSES_ROOT HKEY_CURRENT_USER HKEY_LOCAL_MACHINE HKEY_USERS HKEY_CURRENT_CONFIG HKEY_DYN_DATA HKEY_PERFOMANCE_DATA [EMAIL PROTECTED] /proc/registry> ls -la Segmentation fault (core dumped) [EMAIL PROTECTED] /proc/registry> next I type 'ls' <space> <tab> to get [EMAIL PROTECTED] /proc/registry> ls HKEY_ then I press P <tab> and the bash window vanishes !! And check this too: [EMAIL PROTECTED] /proc/registry> getfacl HKEY_PERFOMANCE_DATA Segmentation fault (core dumped) [EMAIL PROTECTED] /proc/registry> getfacl * # file: HKEY_CLASSES_ROOT # owner: Administrators # group: SYSTEM user::r-x group::r-x other:--- mask:rwx # file: HKEY_CURRENT_CONFIG # owner: Administrators # group: SYSTEM user::r-x group::r-x other:--- mask:rwx # file: HKEY_CURRENT_USER # owner: Administrators # group: SYSTEM user::r-x group::r-x other:--- mask:rwx # file: HKEY_DYN_DATA # owner: dk # group: Domain Users user::r-x group::r-x other:r-x mask:rwx # file: HKEY_LOCAL_MACHINE # owner: Administrators # group: SYSTEM user::r-x group::r-x other:r-- mask:rwx Segmentation fault (core dumped) [EMAIL PROTECTED] /proc/registry> There's something badly wrong: it seems that any attempt to stat or otherwise access it causes a segfault. Tell me, do you suppose the spelling mistake between HKEY_PERFOMANCE_DATA and HKEY_PERFO*R*MANCE_DATA could be resulting in some internal routine in cygwin's registry->filesystem mapping code getting called with a NULL pointer? cheers, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
